Thank you for refuting these out dated and dangerous theories of ADHD. As the youngest of 5 boys, I grew up in a home where intense physical play and wrestling was a common daily event. I've lived 48 years with moderate to severe ADHD and in spite of a life of intense physical play (I do Jiu Jitsu), I still have ADHD. ADHD is not due to the social environment or lack of physical play. JPs dangerous theory is similar to when we blamed refrigerator mom's for causing autism. Science and research matter! I'll share this with our ADHD parent support group!!! Thank you, Dr. Barkley!!!

Dr. Barkley, I'm sending you a virtual hug. My ADHD isn't an excuse to lose, but it is an exhausting daily battle, and soldiers like you who fight for us daily gives us strength and courage to keep going.

Thank you! You've put so much more effort into this rebuttal than it deserves. Sadly, it's so much easier to speak with confidence about things one doesn't understand and become a celebrity than to actually research the body of evidence. The wise man knows when to say, "I don't know." When someone confidently answers every question posed to them as if they were an expert in everything, it's sure to be pure sophistry.

I find it crazy that those are saying an expert such as yourself didn't provide evidence. Doc, you've been instrumental in the modern understanding of ADHD with your studies, and have personally opened my eyes through what I went through my whole life. My brother who has ADHD alongside PTSD (due to his time in the military) urged me to do research on it when I asked, and I'm so grateful for his advice and your expertise. You encourage hundreds, if not thousands of people to do better, and be better. Love your videos, though, I have to take them in chunks, lol. :)

Please rebut Gabor Mates views on ADHD🙏🙏🙏 Thanks for this! Terrible to see celebrity voices promoting the false ideas I’ve been fighting against for decades!

JBP fanboys are so annoying and none of them have read his magnum opus "maps of meaning". But the academic community has really been dropping the ball lately with respect to scrutiny imho, and that's very very dangerous. Having lived with ADHD for almost 40 yrs, I'm grateful for your dispelling of misinformation and hype. It's just counterproductive to progress without these kinds of thorough critiques. If nothing else but for posterity, this is an extremely important record.

I was diagnosed young, and was medicated up until I was 18. I listened to garbage opinions that dismissed ADHD as a legitimate condition. Yet, I struggled deeply with executive function and motivation my entire young adult life. 10 years after getting off medication, I am back on, and it has been a complete game changer. Thank you for these videos. For being a voice for all of us who struggle!

Dr Barkley, this is an incredibly concise summary of exactly why Jordan Peterson's assertions regarding the prevalence and origins of ADHD are factually incorrect. The last few minutes are so impassioned, it is clear what an amazing advocate you are. As there is already one comment here attempting to refute the evidence you present, may I humbly suggest that providing citations to the main articles (ie. that focussing on showing the underdeveloped prefrontal cortex through medical imaging) be added to the video description or perhaps in a comment somewhere? They would also probably be very interesting reading for many, if they are now publicly available. Thank you so much for your incredibly knowledgeable video and heartfelt advocacy :)

I really appreciate you tackling this issue. Thank you for keeping us all informed!

Someone needs to tell Peterson boys with adhd...all we did was rough and tumble play...that was HARDLY our problem lol.

Thank you for both your thorough refutation and your vehement defense of parents. It's tough enough to navigate parenthood of an ADHD child without an extra layer of judgement. Also, thanks for choosing to spend so much of your retirement communicating science! These videos are so impactful for those of us learning to navigate the disorder, as well as our loved ones.

I haven't read A Different Key (now on my to-read list), but I did read Steve Silberman's book, Neurotribes, last year. I wept to read about the treatment of children with Autism and their families, particularly the influence of eugenics, and the chapter that addresses "The Invention of the Toxic Parent". Unconscionable, indeed.

Unreal. Thank you so much for your work, Dr Barkley. You have been a guiding light for me and my family.

Just a note to you Dr. Barkley: When I was first diagnosed 6 months ago I found one of your lectures to CADDAC somewhere here on KZfaq. Your lectures have become a mainstay for my learning and work on treating of my ADHD. A household stimulated by science and intellectual thought your lectures have even pulled in my husband, who otherwise I've had trouble getting to sit down to understand how to work with me and my brain. I have suspected I may also have CDS but viewing your videos on the topic this week I'm convinced I need to bring the possibility up with my doctor. I watch a lot of lectures on various topics, video essays, etc. I can say with confidence no other lecturer keeps my attention more than yourself. Fitting given my brain and your area of expertise. I just wanted to thank you on two fronts. First, thank you for your decades of solid work in this field and your consistent efforts in making your vast knowledge available and intellectually accessible to the broader public. Next I want to thank you for openly refuting JF'nP. This ridiculous person has attacked every aspect of my existence as a human being and his toxic view on men and masculinity even more abhorrent to my husband than myself (and with adhd you can imagine how raw my emotions I feel). I woke up exhausted from adhd insomnia, in a low mood from adhd burnout and finally clicked on the JF'nP refutation videos just to stimulate my brain into movement. It worked and my mood has improved with hearing someone with real expertise ripping bad science apart. This was the second longer than intended post today but I just felt moved to say: THANK YOU, THANK YOU, THANK YOU.

I can't thank you enough of your passion, dedication and years of research/literature/presentations for ADHD. I was happy to see you taking a stand and correcting mainstream misinformation but was put off at the personal tone. My whole life I've had doctor's, employers, teachers, adults and peers tell me that ADHD is not real. The answer has never been to respond with anger, condescension and personal attacks. NT's have zero perception and little education of this condition but in a world of soo many diagnosed & undiagnosed conditions it is not reasonable to expect it. Society/culture has come a far way in accommodating ND people with ADA/special education/early intervention/treatments. I had hoped that you would have touched on some of Peterson other points like how some personality traits such as low conscientiousness attribute to ADHD. Also acknowledging where Peterson provided helpful advice like his future authoring & accountability talks. Taking a more measured response could have lead to open dialogue and even a collaboration. Regardless, it's not about changing his views but using the wider net of influence generated by responding to a popular figure to reach and educate a larger audience. Please continue to produce your amazing content and efficacy for ADHD. Please consider hosting a public talk, I would love the opportunity to meet one of my heros.

ADHD can be the _cause_ of fewer play opportunities, not the other way round. That goes for both children and untreated / undiagnosed adults.

There is a lot I want to praise about this video and your work in general, Dr. Barkley. One thing stands out though and I cannot stress it enough: it is your firm stance against blaming parents and especially mothers for conditions like ADHD and autism. We are indeed not going back fifty years and shame on ANY scholar who still holds such beliefs in light of the evidence of the last decades.

Dr. Barkley, thank you for creating and sharing this excellent discussion.

This is not only an invaluable presentation on ADHD research, but a profound lesson on professionalism. Thanks Dr. Barkley!

One of the things that kept me from looking into ADHD seriously years ago was precisely his comments on it. It just reinforced my own misinformed beliefs about it being bs. Now I wish I had been diagnosed earlier, my life would have been so much easier. That being said, I still do have a lot of respect for Jordan Peterson but take what he says with a lot more caution. I guess it’s also our responsibility to filter and balance what we take in. Videos like this are very important to clarify misunderstandings and reduce the negative impact of the misinformation. Unfortunately it doesn’t have the same reach as the original claims. Thank you Dr. Barkley!

Thanks for this refutation. It's helpful, even for someone like me who has seen her son make vast improvements to his life with ADHD meds, and who then went on to have personal experience with how much easier life is when ADHD is treated. It's real, I KNOW it's real. And yet, when I heard him say that "nonsense on stilts" about ADHD coming from upbringing, my shame kicked in immediately. I need to try harder, I failed my son, I'm just looking for an excuse to be careless, etc. And then I was able to settle myself by remembering that just because he knows a lot about one thing doesn't make him knowledgeable about everything, and I was able to forgive him his ignorance the same way I don't require everyone around me to be knowledgeable about ADHD. There's no need to run around correcting people all the time. But I'm glad you did this time.😊 Personal experience shows me that what Jordan Peterson says about it is false. My son had plenty of play, both intellectual and rough and tumble. He still has ADHD. I grew up in the country in the 80s and 90s, and there was LOTS of outdoor play for me as well. I didn't know I had ADHD until after my son was diagnosed and I still didn't notice anything strange about him.😅 My whole life made sense, and it was a much more palatable way of seeing things, as opposed to my previous self judgment of being lazy, weirdly unfeminine, possibly a bit stupid, etc. However, in our case, it is true that it's the mother's fault. I have it and I passed it on to him for sure, and my daughters probably. I feel sad about that because I don't want them to have trouble. However, I also passed on good things too. (And other bad things, like short-sightedness) Overall, I feel like they're lucky to have a parent who understands the struggle and will push them to do better but without making it a character issue. I think they're wonderful, and even if I knew I had ADHD before having babies, I would still have wanted to have them. We'll be okay.

Let’s get Jordan on your show!

Whilst I've been struggling on and off titration again for my ADHD, I found you for the first time and I will be forever grateful. I just wish we had more professionals like you available to us all for treatment.

Thanks for your videos man, and for keeping it up still. I used to watch lectures/talks you gave years ago and it helped a lot, and it was a happy surprise seeing you uploading videos on your own channel. I tried omega3, mediation, you name it, all the "holistic" treatments imaginable, proper medication without using it as an excuse or crutch has made all the difference for me, since 2012, thank you.

Scholars who turn themselves over to pop-psychology and do the international talk tours like stand up comedians will always run aground against scholarly rigorous science. The very nature of their intent in doing this is to reuse and propagate any assumption that will be accepted by more people. Their purpose is bums on seats, whereas scholars like Dr. Barkley, and myself (now retired) have one core purpose why we dedicate and value scholasticism and rigorous research; and that is to relieve suffering. JP like those before him have a conflict between that purpose, and the business model of more people equals more income for themselves. He can not avoid this, and if he cares only to break even, the. There’s quite the narcissistic ego driving the desire to be loved by the masses, and conduct pop psychology lectures like they were building a mega religion!? And to have the capacity to review and consume the corpus of research on the subject and do not do so. Is ethically abhorrent for a scholar. I believe that one must disclose that they are an agent of pop psychology, and leave their PhD at the stage door, or disclose that what they say on stage will be mostly personal opinion! He causes harm (maleficence ) which as a scholar he would have at once made a commitment not to do, but as a true clinician in any situation always seek beneficence;to do within one’s power all that is good for working to relieve human suffering in his or her professional and personal life. Dr. jMD, PhD (Ohio). Thank you Dr. Barkley.

I grew up with 2 brothers and a neigjborhood full of kids pre internet. All we did was play. I have done competetive athletics since 3rd grade. For 30 years i have trained 2 to 4 hours a day. It seems to take the edge of my symptoms but I still have adhd. What about play as a necessity for appropriate social behavior? I remember two books i read years ago. One was john Gottmans meta emtion and families. In it he stated rough and tumble play, particularly with father socialized against too much agression. The other book which i think was called play had resewrch about interviews with incarcerated men which showed many had impovershed play histories. Thanks Dr Barkley peterson is hugely popular right now so thjs is ne3ded

Thanks for putting the extra effort into a more informational version of your previous popular video, even though I'm sure it will get you fewer views for your effort; that's the nature of the algorithm, I suppose.

Thank you for your expert response to an opinion that is in great danger of misguiding millions of people

The conclusive comments you made at the end were quite moving, thank you for finishing off this dissectment of poor science with a blunt telling off for even poorer social science from Peterson.

Thank you for your generosity with your knowledge. I so appreciate accomplished professionals freely sharing complex information. It is so needed to add to the discourse. A much needed balance 🙏🙏🙏🙏🙏🫶🫶🫶🫶🫶🫶🫶🫶

I. APPRECIATE. YOU.

Dr Barkley you are a true champion. For all you do for so many. Thankyou

Thank you so much for highlighting how these "celebrities" (there are a few of them) may have abandoned science to instead share what is a more popular view in the public. It is so helpful to have an expert go head to head here in an accessible way to deconstruct their arguments. I worry that some of these "celebrity experts" put their popularity before the wellbeing of those their falsehoods may harm (popularity over accuracy). Thank you also for raising awareness about this mother blaming. I also noticed Gabor Mate do this in his most recent book and promotional talks around it..a lot of woman blaming for their ill health and bad luck. The strains of sexism run so deep that these men/speakers may not be aware of how it is influencing their thinking. As a clinical counsellor I have also sat through trauma training workshops where they tell us that ADHD is caused by trauma. There is no accountability for these falsehoods--and the natural extension is that treating the person with ample love etc will heal. This is so incredibly false. Thank you for you great work!

You are truly making the internet a better place, Professor!

Thanks for having our back Doc!

Hello Dr Barkley, I’ve been enjoying this stellar rebuttal to JPs comments and, more broadly, the analytical and evidence based content you provide on popular topics in the space of ADHD. I particularly appreciate how you side with the evidence even when it is not so nice to hear, as is the case often (hyperfocus, intelligence, and creativity come to mind) I am curious if there’s anything for us to know about the age of diagnosis in ADHD. Is there any support for the “fallen angel” theory, where smart kids bumble through early education relying heavily on IQ/G and only later get diagnosed as adults when a larger challenge comes about (e.g university)? How predictive is intelligence of a late diagnosis and how mitigating is IQ/G of ADHD impact? And does this have a bearing on treating or diagnosing ADHD in adults and children? I had a look with my university’s resources but could not find much academic research on this, perhaps it needs a more seasoned eye than mine (and Jack Sparrow hat). Thank you so much for all the excellent work you do.

recently found you through a clip of your presentation on ADHD like 8-9 years ago, CADDAC i think it was? it really showed me alot so now im kinda just going through various videos to get what info i can. though i've yet to get properly diagnosed, im sure you'd agree ADHD might work towards preventing its own diagnosis, haha... i hope to get it done sooner rather than later....regardless that presentation from years ago put into words what i've been struggling to properly express to anyone for ages...i hope to use it and help explain it better to people from now on...good stuff, thanks for all the effort!

I think I said it in response to your previous video on Peterson, but he seems to produce many of his opinions using conservative political ideology rather than genuine scientific research. There are lots of parallels between conservative ideology regarding the degradation of parenting/society/schooling and the idea that ADHD is caused by parenting/society/schooling. At the very least it's not the other popular and damaging route, in which conservatives deny the existence of ADHD (and other disorders of the brain), perhaps going as far as to suggest the existence of academic conspiracies with the aim of promoting pharmacological treatments. Although I fear that would be the evolution of Peterson's ideas if he encounters these solid refutations.

I would love to hear a presentation from you on a summary of some of the other most common pop pschologogical misconceptions about ADHD. You mention many of them here and there across other videos, but i would be curious, what do you think are the most prevalent and perniscious misconceptions out there? Thanks for everything you do!

Thank you for addressing these old fashion ideas about ADHD because I have it and I can tell you that none of this out dated research applies to me or to my family. I think it is very dangerous to compare us to rats because our brains are far more complicated. I am a female who was diagnosed 12 years ago and I can tell you it has been an eye opener for me. I am now 70 and I knew I was different than the rest of the kids around me. I didn't know exactly what was different about me, but I knew it wasn't because I play with kids or my rough housing brothers.

Yes Doc! Overturn the stigma!

Thank you for these videos on JP.

Thank you for the clear presentation of the claims made by Dr. Peterson (based on the ideas by Dr. Panksepp), the argumentative holes in them, the missing evidence for them, and the various evidence against them. Making these claims in the wider public, as Dr. Peterson did, and implying they are true and supported by science, is scientifically irresponsible. The situation is difficult enough for people with ADHD. People with ADHD and the public in general need a clear view of the actual scientific results.

You are an angel sent from heaven. Thank you for exposing the lies spread by celebrities.

Reposting from part 1. THANK YOU! I too was infuriated by Jordan Peterson's remarks with regard to ADHD (and several other topics he has covered, including depression). While I was initially impressed by some of his ideas and arguments, I quickly began to recognize his rigid thinking and broad generalizations with regard to the experiences of others and his right wing close-mindedness. With regard to ADHD, he believes that individuals only have difficulty with things they are not interested in, which may be the case for someone with or without ADHD, however what he clearly does not comprehend is that those with ADHD frequently have difficulty attending to those things they are interested in. And when they are very interested in a particular topic, it can make it far more difficult for them to organize all their thoughts and knowledge pertaining to that topic. And yes, the heritability of ADHD is well documented and obvious when you consider the frequency with regard to parents and children with ADHD within a family. Clearly Jordan Peterson has no comprehension of the current DSM criteria for ADHD and the fact that for the past 30 years (at least) we have been well aware that inattentive ADHD exists as well. While medication may not improve performance or make someone smarter, it can help to reduce the exhaustion that would otherwise occur and the time necessary to complete work for those who have ADHD. It can also help to reduce the frustration, anxiety, and depression that often develops when ADHD is left untreated. I just wish "Dr." Peterson would do his homework and remove his ridiculous videos related to ADHD from this platform and all others. For reference...Jordan Peterson ~ The Reason We Have So Many People With ADHD/ADD - kzfaq.info/get/bejne/odhibKWVr5y8nHU.html

Jordan Peterson suggests that IQ can influence job suitability, with some roles benefiting from higher cognitive abilities. However, job success is multifaceted, involving various factors beyond IQ, such as education, experience, and personality traits. What is your opinion?

Oh no, there’s more to this.they’re always blaming the mother we used to play outside from morning till night had to come in when the street lights came on It’s unfortunate that a lot of ADHD adults feel they didn’t either apply themselves or that they somehow were to blame because they were taught that it’s them instead of inherited .

I had plenty of rough and tumble play in my youth and it I have some serious level ADHD in my 40s. Let's also be honest, love Peterson but he loves to speak about things he knows little about with great conviction.

Yep. Psych 101...basic twin studies is introduced and the methodology is deep and very sound. It's well established science that forms the basis of a very large amount of studies for decades and decades which has already undergone rigorous scientific vetto g and critique. It's always important to ask questions, but one KZfaq commenter making a statement off the top of their head is not going to suddenly come up with a criticism of twin studies that calls into question the entire field of research involving twins.

"Nonsense on stilts" 😂 such a perfect description.

I like pissed off Russ 😊

I have experienced the symptoms of ADHD since childhood. My daughter and I were both diagnosed with ADHD. In addition to being diagnosed with ADHD, I recently found that I was pre-diabetic and my whole life I have had low HDL. I was advised by my daughter's neurologist to have Mandy start taking folate and continue taking magnesium. We are taking Solgar folate. I just received a call from my primary care doctor at 6:00 p.m. saying that my blood sugar levels had improved and my hdl was up. He said I must have been taking my metformin and concentrating on my diet and exercise but that is not the case. I stopped taking the metformin when I started the folate and magnesium because I had read the might not go well together. I had tested positive for having a low level of anxiety when I had been tested for ADHD. My anxiety has resolved. My concentration is better. My mood is improved. My energy is improved. I have less food cravings and I feel the ones I do have are manageable. I feel like my circadian rhythm is improper synch with the sun where before I would not become tired until about 1-3am and would have huge crashes in energy depending on when I ate.

absolutely amazing how genetic ADHD is. i would love to get my profile of this. fascinating.

WARNING: LONG WINDED COMMENT FORTH COMING! I grew up with 2 older brothers and 5 cousins. All of us were born within 5 years of one another. We were thick as thieves, 3 girls and 5 boys. Our moms were twin sisters, both I suspect have ADHD. Now, we played “war”, “wrestling”, recreated t.v. Game shows such as The Dating Game, Beat the Clock, Jokers Wild, pretended to be cooks and had to create recipes, went swimming, and explored in the woods.On a perfect day we might find a mud hole, put on rubber boots and then, with our feet cemented in the mud, would try to take down the others. Pulled couch cushions off and use them as armour to crash into one another. On a sunny day we’d sprinkle Tide on the drive way and pretend the suds were an alien life form needing to be washed away. We weren’t trying to establish dominance. We were having fun and were always empathetic and caring if someone was hurt, helped if someone was struggling, and kind when we went too far. Well, most often, most times LOL. In any event, we always made amends at the end of the day. I have ADHD, and suspect 1 brother and 2 of my cousins of having it. Again, both our mothers, twins, seem to have strong signs of ADHD as well., 2 of us kids are girls. Out of us 8 kids, the four suspected/diagnosed with ADHD have had police issues, drug issues, learning issues, anger issues, etc. The other four went to post secondary education, have had fantastic jobs, stable relationships, and interact with others quite well. Hmm? What’s the connection? When young, we had nothing but opportunity to roughhouse, play, have social connection etc. In fact, our parents were often exasperated by our rambunctiousness BUT they also didn’t or couldn’t reign it in because they were also struggling with the same issues but in adult form. Point is, even if poorly made, our family is the perfect counter argument against J.P.’s thoughts on ADHD. He seems to need to appear as an expert on everything. Thank you a million times Dr. Barkley for standing up for those of us with ADHD, the research and, the EVIDENCE!

Rats definitely do engage in reciprocity in play and social interactions, I have seen my pet rats bring pieces of food to all their companions before themselves eating, I have seen them go and fetch a friend to show them a new way they have found to get inside our couch. They explore togeter and share, and in lab studies they've been shown to turn down treats in favour of saving another rat from drowning. In low stress environments, these prosocial cooperative behaviours tend to emerge more obviously. Rats play fighting is still a poor model of hyperactivity in ADHD, but rats are a lot more complex and prosocial than a lot of people give them credit for.

Thank you for taking the time to elaborate on the topic, Mr Barkley. It is interesting that Jaak Pankseep later argued that increasing opportunities for childrens to play could play a role in overcoming ADHD . Perhaps this could be linked to the know widely accepted stance that exercise helps to lower ADHD symptoms

Ohhh do Andrew Huberman next!

Bravo! Thankyou for making this second video. Its surprising to me how many people read/listen to Peterson and believe his toxic filth. However, these people usually love talking about him and as such “out” themselves very quickly and I know to quickly distance myself from them. Comparing humans to rats is as ridiculous as him comparing humans to lobsters. We are not rats, we are not lobsters. There is no worthwhile comparison to make there.

I have ADHD which I believe was caused by a nuchal chord I think it’s called. I was born blue and was never diagnosed as a child but showed clear signs it just wasn’t well known where I’m from. Can’t say for sure it’s the nuchal chord but I’m sure that amount of asphyxiation could cause neurological disorders.

And anyway, I thought the nature versus nurture was sorted out decades ago. We know that genetic abnormalities happen. They are there from conception and there when xhid is born. How the child then develops, once born, will of course vary according to environment. But the genetic studies are good data. No one disputes that later environmental conditions will then act on the development of behaviour patterns. But the adhd is there at the start. I want to study this. And have begun a college course to prepare for entry to university as a mature student. But I admit I'm having terrible difficulty. The adhd is difficult, but the trauma I've accrued over my life is making it exponentially more difficult. I'd really appreciate a bit of advice if anyone has the time.

Excellent video. For anyone listening and short of time, the meat of the video starts around 20 minutes in

I used to make youtube videos, you have so much quality that I think your videos do very well if you do shorts ontop of the full length videos you normally do. It really helps with how youtube ranks your videos

Sadly, Jordan subscribes to the Gabor Mate ideology. And a lot of ADHD coaches rather believe this type of stuff and think there is a cure, then accept that brains get a li'l funky

Absolutely love the ending ❤

*stands up and claps* thank you so much!

Good video, as the last one was. The YoutTube algorithm loves spicy takes and mentions of controversial figures. Peterson is one of those talking heads that gets lots of clicks by being provocative. I think he bases his arguments more on what he thinks will get a reaction than what he actually believes. I like these debunking videos because they are educational but it is possible to get pulled down into the social media muck if you take some of the comments too seriously. Also, "Case closed, Jordan" sounded so amusingly incisive at 1.75 speed, lol. That dude hasn't read a research paper on this topic in years, I bet. He just says things off the cuff based on decades-old recollection.

Peterson also said couple of years ago in an interview, he wondered if being trans is related to having a lack of play opportunities as a child...

While I found some of the information by Jordan Peterson and Gabor Mate' useful, there is always the risk by any expert of getting things wrong. Hence this video series by Russell Barkley is very welcome, to correct the information about ADHD and add new information to it. The principle "K_'ll the Buddha when you meet him" means you cannot trust on one expert only, that any expert is likely to be wrong at some points, or many points at times. That one also needs to keep on thinking about one's own context and if or how the information applies and also add in new information when available.

Dr. Barkley, you got me at 15:00….if one believes that people evolved from primates, then it’s easy to extrapolate anything! But, consider if people are not a species at all but were created by a powerful and intelligent Being….the argument for intelligent design far outweighs the argument for evolution….

This is like Mike Tyson in his hayday vs some KZfaq boxer.

35:28 *Drops the mic* All jokes aside, it's absurd that JP makes such black and white statements. With millions of followers, that look up to him. Mistakes can be made, but I saw the video and he was so sure of himself saying those claims. So many people believe him, that clip is being shared on reels and tiktok like a parasite. He's really responsible for dangerous misinformation. I really appreciate what you do Dr. Russell, you are the reason my family finally understands my struggles and with your advise trying to improve my self everyday!

I would absolutely love to see a discussion around this topic between yourself and Dr Peterson. I think it's important to highlight that nobody is infallible. I am a huge fan of his work, but I won't blindly defend someone just because I like them. I'd rather see a constructive debate between the two of you - that's where we learn the very most. Great stuff, Dr Barkley

Thanks Dr Barkley

Hey doc, can you do a lecture on adhd impairing object permanence?

More views why? Because your prior video was "argumentative," and people 1. love that arguing, and 2. the algorithm gives more weight to negative stuff, and that generates more clicks. Your video echoed my own opinion of Peterson's ridiculous claim. Still, glad you are putting this video out. The dog study was small and was not replicated, anyway. He knew it was meaningless. Something has always been wrong with Peterson, from his early days.

Okay. I think I have the possible explanation why he got stuck with the rats. The thing is. It looks like he was following a lot of those play studies and what was recently found - those rough plays in rats are not about just domination. In those experiments if the strongest rat would win more than 3/4 of those plays - the weakest one would stop inviting to the play. Which leads to strongest one intentionly giving up from time to time. Which is way closer to the way humans treat fair play(no-one would consider losing every time interesting) and its way more advanced that "strongest rat wins and establishes hierarchy". That being said. It has little to do with adhd so it's just the case when he applies the knowledge from the area he is up to time(play/dominance in rats and mammals) to the area he is not(adhd). Boooo for that.

28:25 - as a mother. Thank you!

Thanks!

You know who I think seriously has lacked outside playtime in the past decade? Jordan Peterson. That dude touches NO grass, and it shows.

Be great to see you two do a podcast! (His or yours)

Hello, I agree he is wrong to assert something as fact based on such scant research that may have no correlation. I’m wondering this though: I’ve seen brain studies that show brain differences in children who’ve been spanked/abused… so that shows that brain imaging also capture effects of environment not biological destiny. Have you compared the brain differences of adhd patients and survivors of childhood abuse? Any associations? Are there any associations with adhd and ACE scores available by any chance? Could it also be a mixture of nature and nurture (or lack of it)? Biology doesn’t equal destiny but there are still biological predispositions that can arise only within the right (or wrong) environment? This also has me thinking of a recent episode on Hidden Brain where a female scientist breaks down the biological assumptions psychology had taken in as a result of the marshmallow study on children. She discovered that it was the environment of safety/reliability of rewards that allowed children to not eat the marshmallow but instead wait for two. She found children who had been in an abusive environment were the ones to gobble up the marshmallow instead of wait for the second because they could not trust the reward to come. They had learned that they better grab the good in front of them. And of course this leads to problems with future planning/finance/self-control in later life. I think there’s also a possibility that this kind of response may not come only with an abusive environment but also one where the parents break promises or they’ve somehow internalized lack of trust/reliability of environment in some other way (like divorce/moving etc. Also, there may be a lot of kids who had even a minor head injury that led to a different development of the brain? I had a brain injury in the military and looking back, I think I’d already had adhd as a kid… the head injury definitely made things 100 fold worse but I’ve learned lots of adaptations. Also, benfotianmine has shown success in helping the brain grow after brain injury ( I’m now on it after discovering) so it would be very interesting to see if benfotianmine treatment (fat soluble B1~very inexpensive) has been studied as a potential treatment for ADHD as well! Super enjoying you channel and your passion!!! ☀️

I've been a female for 51 years. I have had ADHD for 51 years. I have always been physically very (dancer/dance teacher/professional aerialist etc) active. No matter how active, I still have ADHD. It gets worse with low activity (deeper internalisation) But either way it is still always there. Diagnosed 3 weeks ago after a lifetime of misinformation, misdiagnosis, and hopeless psychologists. If you meet me and get to know me, it is so bleeding obvious. Jordan can go jump.

We need to understand that JP is not really talking about ADHD in these statements nor is he interested in it. His overall message is that there is a natural dominance hierarchy built into humans and any cultural attempt to suppress or change this hierarchy is leading straight into hell. To him, ADHD is just another little piece that he can abuse to promote his hierarchy fetish. It’s sad to see a generally intelligent and knowledgeable person act in such a way but it’s also helpful to keep this in mind when evaluating some of the others things he says.

Deliciously schooled. 💙

I did not hear Jordan Peterson mention rats....rats! I have been a teacher and coach since graduating college, for over 14 years I coached youth sports and I could not have agreed with Jordan more than on this topic, my first hand observation of student athlete success stories would point to no other hypothesis, Children do not play organized "coached" "team" sports enough, the more play time children get more social they become the fruits are too numerous to mention or refute, so I refute your refute completely. No public school student should not go thru the system without having experience playing on a "team" at any level. Its all good.

So glad you are doing this, I am not a fan of JP nor anyone who uses him as a reference material

Thank you Professor!

I'm generally a fan of Jordon ,he does much good but it's been clear for some time that he's not at his twinkling best. I know he struggles sometimes with what I think may be depression and I understand he has had some treatment in the past. Jordan has also had a fairly horrific time dealing with devastating illness that threatened the life of his daughter and indeed, it emerged he also had similar dietary sensitivities that made him quite unwell. This iss no excuse efor irresponsible comments to a public who , being uneducated in the field, and having possibly been saved by some of his perceptions about life in general, may just believe Jordan blindly. I have adhd , diagnosed when i was 57.(im now 60). I also have cptsd and major depressive syndrome, all due to an abusive childhood. I have noticed that jp seems to have been displaying a serious amount of arrogance ,of late, which saddens me enormously. I am one of those who benefitted from JP's straightforward philosophy and advice in the past. I'm aware that psychiatrists and psychologists have their specialities, and generally ,I see that this is clearly stated in most cases. I'm disappointed and while JP is clearly a very intelligent, possibly brilliant man, but there are many brilliant minds at work, trying to help those of us having difficulty with our human condition. It's also interesting that Gabor Matè, in an interview on the Diary of a CEO series,, recently stated that he has changed his earlier opinion and also has said that adhd does not exist. He claims there is no published research showing that there is a genetic aspect to adhd either. His statements were not backed up with any references at all, and again, I'm dismayed by this strange change of opinion without any research to cause said change of opinion. I do note Gabor Matè is not young, and again , this is not his speciality. And also, again, I notice a considerable amount of arrogance creeping into his speeches. Coming from a man who used to be so very humble, it actually hurts. I call on JP and Gabor Matè to quote the research which has informed their assertions. I'd really like to see that research. I'm deeply disappointed in both of them. JP is brilliant IN HIS FIELD, but has no foundation on which to base his pronouncements. Please keep going Professor Barkley. I, for one, am struggling badly, very badly, and I pray for help to come from your research. It seems that JPs re education in social media may well be justified. He's been foolish and I'm really hoping he can own this and put it right to regain the respect I had for him.

Now it’s very clear why JP was stripped of title. I actually felt a little sorry for him until now, only hearing his side of things through the random clips that pop up on social media. I wish scientific discourse was more popular, instead of just hot takes.

Anecdotally, people I know who have a clinical diagnosis of ADHD were free to rough and tumble play, climb trees, roam in acres of grass and forest. Even at school they had massive grounds where they were supervised, but basically just had to respect each other.

@russelbarkleyphd2023 Hi Dr. Barkley, your videos are immensely helpful to me in raising my daughter. As a clinician and parent to an ADHD child, I am very disheartened and angered to learn about leading clinicians providing completely inaccurate information to the public about ADHD, further stigmatizing and delegitimizing the disorder. Can you please make a video refuting the claims on ADHD Dr. Gabor Mate made recently? Thank you and sending regards from Los Angeles!

Thank you for this.

It would be interesting to see you two have a conversation about ADHD. To me, it just seems like he needs more exposure and education in this specialty. You would be amazed at the amount of psychiatric doctors and psychologists that are misinformed about ADHD.

I can't pretend to be surprised JP (who thinks we should conform to patriatchy because of lobster brains) is similarly ridiculous about ADHD and rat brains. It's one thing to have serious academic disagreement over science, particularly where there is good evidence for multiple hypotheses. But this? A celebrity psychologist peddling flawed studies to discredit settled science is just abhorrent, and trult harmful.

Tell em Russ! 💪

I think 🤔 that when we are kids (though there are so many varieties of children) they are "over exaggerating" everything from Play ▶ to disobedience, to simply test borders. And when they grow up they will get less "playful and testing borders". Of course we will always have exception later in life - everything from the academically (medical) focus student to the incarcerated (criminal) person. 😊

thank you Dr russel barkley for This video ; i understand the brain activity of me now better than before👍

Wow! This is a master class in how to refute misinformation, and I applaud Russell Barkley for providing it. I would like to hope that Jordan Peterson, if his opinion was offered in good faith, would be -- okay, I'm going to say it -- man enough to recognize all his errors that have been flatly disproven by sheer data, and to publicly retract them.

I believe the question that sparked his response, which you initially responded to actually came from a young woman, presented in an interview to JP, so the fact he immediately ignored that, and went into a tirade about boys is very telling. And he’s not entirely wrong about boys, but he used that to dominate the conversation, using a strawman fallacy and a false equivalence fallacy.

Thank you for refuting the misinformation pushed by a non-expert celebrity who happened to be of a high status. I'm the mother of an ADHD boy and I know that he never lacked opportunities to play.
