Another good optical illusion is sitting on a train parked at the train station. You look out your window at another train parked at the station. It moves off in the opposite direction to where you are going. You know that you are stopped but you brain is telling you that you are the one that is moving & not train that actually is

@julianunwin6577 2 ай бұрын

I think a large part of the attraction to the A + B option is that the Bank Teller (only) option makes it sound like that she's not involved in any activism at all. Based on what we know about Linda, perhaps it's unlikely that she would go into banking without such an outlet, but we're only offered feminism. Option A, of course, doesn't exclude all kinds of other activism that she might be involved with, but that's not necessarily clear from the way the question is posed.

@Nikonik66 21 күн бұрын

In the 'Linda Problem' we weren't given the choice that she was a feminists only. In this day and age, the probability that a single, 31 year old, university philosophy student is a feminist is nearly 90%. So, that was my reason I chose option 2. There is no bias that would make someone think she was a bank teller. Had we been given that choice alone, I believe more people would have chosen option 1.

I had an argument with my wife about the odds in our national lottery. This involves choosing 6 numbers between 1 to 49. First it started with her disliking my selection because it had three pairs of sequential numbers. So "What are the odds of that happening?" I then pointed out that every selection has the same odds as any other. Even the sequence 1,2,3,4,5,6 is just as likely to win as any other sequence. Naturally she insisted "That's never going to happen". So I then pointed out, if you really believe that, since EVERY sequence of 6 numbers has an equal chance of winning, we should stop doing the lottery altogether. On a side note, the selection 1,2,3,4,5,6 is a bad choice because, in the event that you win, you'll be sharing that prize with a LOT of people. Better to choose something a bit more random because, although the machines used to pick the winning numbers make random selections, people entering the competition DON'T make very random decisions.

Here's why I think the Linda problem is often answered incorrectly. When viewed together we seem to want to recast the first option as (1) Linda is a bank teller and NOT active in the feminist movement. With that assumption (logically wrong, but arguably a natural assumption) , picking option (2) makes more sense. The reason is that we discard the "bank teller" part because that's the same in both options, and judge whether or not she's active in the feminist movement, given her age and background. With that (unstated) assumption, option 2 is reasonable.

Also, people have a disposition to try and answer more precisely than required, even when this makes zero sense. For example, if you asked people to give a range when WWII was fought, and you'd win $100 for being right, people will still given limited ranges. The proper answer would be between yesterday and 4 billion years ago. You would always be right, but it lacks precision, and our brains want the precise answer.

@WideCuriosity 4 ай бұрын

The erroneous inference was precisely the point I intended to make. Having made it the rest is reasonable. (I hastily point out I'd answered correctly.) I'm unsure what occurred in the Borg question though. I think having too many options just stymied certain minds.

I find it fascinating that some people will say "That illusion doesn't work on me" or even "I don't see the point of optical illusions". I find some of the illusions absolutely incredible and will study them for ages, but other people aren't moved by them at all. It's strange how we are all the same species, but our brains can be wired quite differently.

@ParalyticAngel 3 ай бұрын

@@AutPen38 Yeah it's fascinating. As always, nature is going the most efficient way, so our brain does. As we live since our birth in rectangular shaped buildings our brain did a lot 3D calculations for its orientation in a 3D world. And with that experience it has also found a way for fast detecting the orientation without calculating it every time. And this fast detecting setting lets these optical illusions work for us.^^ I guess it is made subconsciously. It is the stronger part of our brains and our brain believes what it says, even if we see complete the opposite.^^

The anchoring bias is VERY real in the commercial world. I'm convinced shops show the marked up price crossed out and the "lower" price underneath as a ploy because if you'd just showed the same price on its own, people don't think they're getting a deal. Another phenomena similar to anchoring, though slightly different - and I see this on TV adverts - is the cleaning products that claim "cleans X100 more effectively!" I don't understand how impressed I'm meant to be. I mean X100 cleaner than what? Using my finger? A cloth? Spit? And what do they mean "cleaner?" What metric are we using for that definition? There just trying to dazzle you with big numbers.

Anchoring can also be used to coerce people into answering opinion polls with answers that are different than they would be if various options weren't listed. e.g. You can fake the answer to things like "What tax rate is best out of X, Y, and Z?" when it could be that all those options are higher or lower than you would pick if given a free choice. It's partly why Twitter polls are completely useless. The results depend on how you frame the question and which options you offer as responses.

No it says nothing about the likelihood of being a bank teller. Maybe it's 1 in 10,000 doesn't matter. That probability is the same and also being a feminist is restrictive so option 2 is less likely by definition. Both may be very unlikely but 2 is less likely than 1

The lesson is: be wary of people adding strange conjunctions into all of your choices, they're tricking you into accepting and confirming something as fact, while distracting you with the rest. Just reframe the question and leave the weird bits out and answer THAT confidently. Watch them crumble. Bonus points if you chide them for the infantile word games.

Something that helped me through the conjunction effect is realizing that all the situations where A occurs include situations where A and B occurs, as well as situations where A occurs but not B. With the USSR example, the possibility of the US cutting diplomatic ties with the USSR includes situations where the US cuts diplomatic ties with the USSR due to the USSR invading Poland, as well as other situations which would cause the US to cut diplomatic ties with the USSR.

I don't accept the USSR / Poland / US question to be a "Linda" problem. There are facts that can reasonably be considered in terms of wether Poland will be attacked, and real world events that might realistically inform a likely possibility of events known to the person being asked. Consider asking that question in 1939, 2019 or 2023.

The obvious flaw in the Linda Question is this. All the information would make it far more likely that Linda is active in the feminist movement than working as a bank teller. Therefore when given a choice between a far less likely outcome alone or a less likely outcome plus a highly probable outcome, we are far more willing to accept the bank teller, which would seem unlikely given her bio, together with a stance which would fit Linda well as described. It's not simply mathematical probability and what you call bias is actually the brain working with all the evidence presented, referenced to all previous experience, making what seems to be a reasonable conclusion.

@Whitehorseandryder 5 ай бұрын

It's a trick question to begin with the way it's worded and answer choices presented, makes it seem like her being a bank teller is part of the information presented, not part of the choice to be considered. I thought it was asking if shes a feminist or not, not a bank teller or not

I can see where you’re going with this but it still doesn’t alter the fact that the conjoint statement is less probable. Bank teller is available in both options so bank teller alone is most probable. Tez

it is worded this way to showcase our brains bias. if the choices were "she's a feminist" or she's a feminist and a bank teller" nearly 100% would choose "she's a feminist" because it is more probable. the fact that she's a feminist has nothing to do with which answer is more likely, same for her being a bank teller, but because of the backstory given our brains only lock on to what we perceive to be the "righter" answer. it's a brilliantly worded, well thought out question.

Ok, a little dizzy after this video Lol.. I'd just like to say, I got the original Linda post correct. Here's my crazy reasoning.. She's deeply concerned about issues of discrimination, so if she's a femminist activist, then that's kind of discriminating towards men.. a little hypocritical if she's concerned about all issues of discrimination.. 🤔 Does that make sense?

The Linda problem: The question seems poorly defined. It is presented in such a way that it can be and probably is interpreted as there being only two choices for Linda, and so it is a given that she is a bank teller. The chance of her being a bank teller is then precisely 1:1. The question then becomes: what are the chances that Linda is active in the feminist movement vs not being active in the feminist movement? Colllege, a degree in philosophy, deeply concerned with issues of discrimination and social justice, participated in antinuclear demonstrations. Considering the events of my life over many decades, that makes the chance of her being active in the feminist movement very high. Also, define "active". Many are what are called "coffee shop feminists" who might call themselves "active" but who do not engage in demonstrations or protests. By your conclusions, I would say that what you mean is, in the totality of all things that Linda could be, what are the chances that she is a bank teller? What are the chances that she is a bank teller and active in the feminist movement? How do those chances compare?

@verynearlyinteresting 4 ай бұрын

I agree with what you're saying, and this is speculation on my part but I imagine if there was a third option: "Linda is neither a bank teller, nor a feminist activist," a lot of people would still go for an option including bank teller in the answer. This third option seems even more likely following conjunction logic, right? One conjunction is always more likely than two, so no conjunctions must be more likely than one. After all it's more likely you are not a random thing than you are one. But....my thinking is that because 'bank teller' is included in 2 of the 3 options, it tricks us into thinking it must be more likely because its included in more of the potential answers. After all, why would it be repeated in the possible answers if it is not so. But in reality I don't think it has any influence. I believe this may be yet another form of bias based on the answer appearing multiple times.

Seriously, the" Linda Problem" responses are created by the question itself. The human brain is being asked to make a binary choice between a neutral option (bank teller) and a spiced up option (bank teller who is active in a feminist movement). The preface to the question describes Linda as being outspoken and single, a philosophy student and concerned with issues of discrimination and social justice (an active feminist would need these qualities). When given two options in this context, the human brain will pick the "best" choice based on the information available, not a choice based on an abstract mathematical probability of "two or more options conjoined being less than one." If the question being asked was a mathematical one, the response would be different, but this is a logic/probability problem based on limited information demanding a response. The real question here is: Why does the human brain feel the need to respond to the command to answer a question with such limited information? Why not respond: "not enough information" and simply not answer it?

@johnbird7357 Ай бұрын

I play when I'm bored, either red or black, odd or even, but not for real money. More than likely I've got ten minutes until a film starts so I tune to Channel 5 and play with imaginary stakes. I know that the longer I play the more likely I am to lose as the house always wins, and I never use the MartIngale system of doubling your stake as it's pointless. By spin number 8 you'll be skint if you lose, staking £256 for example, but you're already £255 down, you only stand to win £1. As you know there are no winning systems in roulette, but if I 'play' £1 on red on spin one, if I'm right the next bet is £1 on black, but if I'm wrong I treble the stake on spin 2 to £3 on black. If I'm right the next bet is £1 on red, if I'm wrong the next bet is £9 on red, if I'm right it's back to £1 on black and wrong is £27 on black. And so on, of course If I was in a casino I'd probably end up losing my cash, but on the telly, I win every session, and have only got to a £243 stake once, and it won. In the video he says 21 losers is 2097151-1. It's not, that's the 22nd toss, the 21st coin toss, or anything that's an even money shot, is 1048575-1. As for scratchcards I have never indulged. My younger sister, who couldn't get the square root of 16 without a calculator, insisted she won £200 on one about 10 years ago. Being pedantic I told her card cost £2 so she won £198. I said to her 'You want to stop now because as long as eggs are eggs the chances of you winning again in the same shop buying one ticket every Sunday are slim to say the least. The response was 'Well somebody has to win.' Yes, you guessed it, a week before her 60th birthday she purchased another ticket along with the Sunday papers and some chocolates. from the same shop. She won £250,000. I've been backing horses, boxing, dogs, football and tennis all my life and my biggest win was £7,000 some years ago. There's no justice....lol

Good video. If I’m not mistaken, kind of related to the coin flip, (each flip is basically always 50-50, because each flip is a new flip with only two options, though it’s been shown that whatever side is facing up before the flip, over the long run, has a very slight advantage). Anyway, in a lottery, the odds of winning numbers being consecutive numbers is just as likely as any other combination. That feels like gambler’s fallacy. Liked, subscribed and notifications.
