Often people make decisions that are not “rational” from a purely economical point of view - meaning that they don’t necessarily lead to the best result. Why is that? Are we just bad at dealing with numbers and odds? Or is there a psychological mechanism behind it? Sara Garofalo explains heuristics, problem-solving approaches based on previous experience and intuition rather than analysis.

Irrational decisions go well beyond just the phenomena discussed in this video. Humans are not so much a rational animal as a rationalizing animal. We are very good at coming up with reasons for things that we already want to do.
+LagiNaLangAko23 actually I'm aware of this, I first want to do something an then I come up with the reasons behind it.

Loss Aversion is a powerful motivator for a great many people. Whenever you are in the position of having to persuade someone, you will often be more effective when you focus your argument on what the other person has to LOSE, rather than something they have to gain.

@@deansamv Happy to help. By the way, I checked out your channel. You are a very creative person.
@@pritamboy9889 I clicked to see your channel. You have a lot of subscribers despite not having that many videos posted. Impressive.
@@BeSmarterFaster haha thank you :D
I enjoyed the examples in this video. I like to think about irrational decisions like optical illusions in that we perceive the situation incorrectly. Just as we can recognize optical illusions by recognizing the patterns, we can also overcome irrational decisions.
Check out MindYourDecisions' channel. He makes videos on maths and game theory.
Irrational decisions involve trusting our earlier impressions without evaluating them. Contrary to popular misconception, the impressions arent bad things in themselves and are are the root of creative associations. Having those impressions (as intutions) can be invaluable in generating solutions which rationalization itself has no access to. It's best to use all of our mental resources.

Same, except most of us didn't open Fifa packs to figure that out!
You don't have personal levels of "chances". It turns out you're irrational after all, based on that explanation.
TheReddaredevil223 No, the original poster is not irrational. He just might make irrational decisions. He still is a rational human.
I wouldn't flip the coin in ether situation, because I will take a sure loss over a possible greater loss any time
and I will take a sure gain over a possible greater gain if there is an equal chance of no gain at all.
this also explains why I don't understand most pricing today, it's focused on squeezing out more money, rather than having anything to do with the actual product.
I am a mouse, safe cheese is good cheese.
same
+Tristra Gyopsie If the sure gain is 1000 and for flipping a coin there is a 50% chance to get 10000 and 50% chance to get 500, will you still choose the sure gain?
taking a sure gain in this scenario would be a irrational decision, wouldn't it?
I think we should make a decision base on risk-reward and chance, not the surest way but the most logical way.
PS sorry for my English.
Cheese is bad for mice, they just eat it to survive.
LOL, True.
+BlazingSun46 I agree with you :) There'll never be such choice though :P

What about the irrational decision of watching this instead of studying for my exam?
You just do that because your brain knows its more rewarding
Because it is an irattion choise
Procrastinating, my friend. We're in the same position.

@@iquestioneverything3426 False, you do it because your brain has adapted to do things that you find more enjoyable, not necessarily rewarding.
Reasons of irrational decisions:
-Aversion fallacy
-Conjunction fallacy
-Anchoring effect

There’s a whole lot more than that
I like that you've used a lot of example tests in this video

Me too!
I have been researching and exploring on the basis of decision making process, the effects like cognitive biases, intuition, probability effects and actual data and facts. I'm shocked by how much wrong and blind we can be in many scenarios.
I'm so used to calculate the expected value that I didn't care what I chose for the two examples. and for the cubes, I immediately excluded b as it contains a, and c as it is longer than a and is with a more wrong frequency of colours.
math is good. quick and correct math is better. replace heuristics with it is even better.
very well.... may I ask how were you able to develop these practise of calculating expected value so much that you became better+quicker at it?
don't gamble...working for every cent is frustrating...but the painful experience will also stop you for buying something you don't need.
For the gameshow, i chose to risk the flip on the first round and stick with 500 guaranteed loss on the second.
For the dice, i chose B because it had more green dice lol
I don't like the idea of not trusting your gut though, i feel like it will lead to indecisiveness and paranoia. I think being able to trust your gut, grow from incorrect choices and learn from your mistakes which then informs your gut decisions later in life is an important skill to hone. Not worrying about what's the most optimal decision for everything.
hmm Im super into optimisation and I think it's good on it's own but not in most enviroments
have chosen same in the first example
Irrational is acknowledging reality as it is.
This video is about logic.
People get mistaken between logic and rationality.
My parents can be idiots.
Thank u for uploading this video, I love when we have more material available on utube that talks abt cognitive bias... Thinking fast and slow - Daniel Khaneman is a good read
so many time in psychology they say "intuition is always wrong". I am glad to finally have a proper answear.
Thanks for summarizing "Thinking Fast and Slow" '
+Uncerten I was looking for this. Seen so many videos on TH-cam that just basically picked 1 or a couple of chapters and made a video.
This might be one of my favorite videossss
Great video. We need to teach these to kids. I'm glad TED-ed is stepping up when our education systems fail.
I took the ones with no risk, lol.
Me too and then the narater said if your like most people you chose 500 $ and the the coin flip and I was like no I didnt
+Connor Waud That doesn't mean the narrator is wrong, that just means that you are not one of the "most people"
I did too!
we have a hard time accepting these, together with other WHY questions that psychology tends to answer, ie to the right of ur youtube page with other suggestions of youtube videos on psychology by TED
I flipped the coins z times x'))
This whole video can be explained simply by people not wanting to take a loss.
The outcomes are the same but what you started with is different!
more and more the quality of these Ted-Ed videos are becoming more like TedX. It's been a while since I saw any videos of quality now.
that was the first point
TED-ed never fails to impress me!!!!
Very short recap of Thinking: Fast and Slow
Can we take a moment and give credit to the editor because the person did an amazing job!
Our teacher did an experiment once.
We were split into groups with people whose phone numbers ended with 30 and below and those over 30. Seperated from each other we had to guess the value of a book (pretty big one with pictures etc). The first group said it was about 30-35$ worth, the others went over 60$.
Beautiful, beautiful animation! Loved it!
0:50 You are EXACTLY wrong.
+infrabread true had the same
+sjohban de vos same
And i didnt even think it through i just said it but it is logical
+infrabread Lol, Same for me.
+infrabread I dont think she is wrong. Psychology is not an exact science, but it describes well known patterns. I'm pretty sure out of the 4possible choices the one described was the most chosen, possibly over 50%. Its just that people who had other choices are more likely to comment it.
This is basically taken from "Thinking fast and slow" a very good book, give it some credit!

Ted-Ed "If you're like most people"
Me: Definitely not.
The irony is that if you assume you're not like most people, you are like most people. Most people assume that they are unique.
@@Morneisia the statement has already been declared thus other who don't choose the same are not most people.
Really appreciate your knowledge Sara
Thank you for such a great deep insight👏✨
Next time you are going to make a decision, understand that the intuitive answer might not be the right one especially in situations involving multiple details, numbers or probability. The irrational decisions that you make are a result of ‘heuristics’ (problem-solving approaches based on previous experiences and intuition rather than careful analysis) which is your response to ‘loss aversion’, or people's tendency to prefer avoiding losses to acquiring equivalent gains. However, don’t try to completely block out your brain heuristics because they can be quite effective when there is no time to logically analyze all the possibilities.
Another very informative video by Ted Ex
Love how they used the flat earth theory as an example for theories easilly able to be proven wrong
Gaining something has much less weight cuz earning something or when things come at us we believe we deserve such thing, but when we loss something, we expirience an intense feeling of lack that we think we don't deserve, which is why losing has much more impact than gaining something
I am colorblind and I could not see for myself the examples you listed :(
Tempting........... very tempting.........
I died at 3:45. That scream!
😂😂😂😂😂😂😂
I was exactly hoping badly to read this comment about the scream!! I loved it too, honestly brought smile in the video haha
This is SO Me! Thanks for the explanation.
When it comes to automatic life-saving decisions, intuition outwits logic every time.
I like this. This was fun to see. What a treat. Subscribed.
Honestly I would take the bonus and the loss, because +/-500$ risk for 50% chance only worths it if you have a lot more money than that. It's not just about mathematics and psychology, your financial situation matters too.
They specifically chose amounts that aren't life-changing to their average viewer, which would of course change what's rational. (i.e. they wouldn't suffer dire consequences it they only won $1000,- over $1500,-.)
It's a different story if for example $500,- decided over whether you can securely feed your children and send them to school or not.
I gain new knowledge in this educational video. Thanks Ted Ed.
Can anyone recommend books or textbooks on the topic? I'm rather familiar with the topic, but I'm interested in how writers go about teaching it.
That would be interesting
+d3st88 Thinking Fast and Slow by Daniel Kahneman goes into detail about a lot of this stuff (among other things) and is excellently written.
Thanks, but already read that. Twice.
Adam Smith wrote about this in his Theory of Moral Sentiments. Other behavioral economic ideas are also found, like "fairness".
Over the years, I've come to realize that most people behave irationally.
In so far as every person has at least one irrational belief, I agree with you. Beyond that, people are more or less irrational when compared across a variety of different subjects and beliefs.
***** Your statement is more accurate. ^_^
Loss aversion really does make sense from an evolutionary standpoint. Loosing things usually causes more grief than the success from getting them.
If you have a car, the ways your life could go wrong are much greater if you lost it than the ways your life could get better with two cars. Sure, having a second car is great- if one of them has something wrong with it, you still have the other one. But if you loose your only car, you can’t get work without public transport.
I chose the coin flip in the first round and the bonus in the second round. WTF?
OH MY GOD SAME! Btw it's called penalty for the second round sinc ur losing money
I love behavioral economics!!
Anyone in Dungeons and Dragons would immediately tell you to play it safe and never roll or flip anything
I got the sequence one right!!!
I would not have taken either chance in the game show scenario.
Informative video! Thanks for giving us dome realizations.
i actually choose the opposite
Same, I chose the opposite; risk the win and guarantee the lesser loss.

"Thinking, fast and slow, " By Daniel Kahneman. You're welcome :)
I never chose to flip the coin
So really most this video was made up of noticing our behaviors with probability, and then matching these up with scientific terms to make us feel smarter. How fun.
I would take the guaranteed bonus/loss at both times.
That still proves the narrator's point. Because the relative outcomes in both situations are the same, it's more rational to make the same choice in both situations.
You can read more about cognitive biases, logical fallacies, and heuristics in Daniel Kahneman's spectacular book "Thinking, Fast and Slow".
I'm not like most people. I went with the simple guarantee both times because I know my luck is terrible.
same, i also know my luck is terrible, so i played safe both times
Nice advice...
i flipped a coin for both. i guess I don't care because getting $1000 is good enough.
yea i need a telescope!
The Book 'Thinking, Fast and Slow' by Daniel Kahnemann says the same thing. Awesome read.
I'm the opposite of most people, I chose to flip the coin in the first round and take the guaranteed loss in the second.
idiot
+Nicholas “LB” Braden doesn t matter is a wrong answer , does not make u special
IMMEDte dissassociating fallacy
+Nicholas “LB” Braden I think it's because she said we had won 1000 from the first round, so at the start of the second you're like 'if I spend 500 I'm still 500 up'. Or that's how I thought of it anyway.
Challen Bellamey I'd rather take a loss I know about than risk taking a bigger loss.
I feel like sometimes the very essence of intuitive thinking makes us feel satisfied about the choice we make and for that if the decision is not really affecting anyone negatively i think there's nothing wrong in going ahead with it
“Give me a name beginning with an H”
*José*
I went with the coin toss on the first round and the automatic loss on the second. I think of game show money as imaginary until the end of the round, so I'll gamble on a chance of gaining nothing, but I'd rather be more secure once I've already 'earned' it.
Basically, it's just a different flavor of loss-aversion: I'd rather gain nothing than lose double.
There you go!!
i wouldn't flip the coin in either of them xD
id flip the coin in both.
One of the only TED ED vdos which i understood😅
How about if I got the exact opposite in the first experiment? *=/*
Me too
+abdullah alshudukhi yeah me to XD.
+abdullah alshudukhi It probably means you lot are people who focus on the gains rather than the losses (unlike most people).
Detective Shaft Maybe
While I understand the overall concept of the video, there are a couple of issues:
The projected outcome of the game in whole is correct, but once you make it to the second round, the Ev of your decision has changed drastically where you should ALWAYS be taking the coin flip as it’s the only outcome leading to a positive Ev.
As a poker player, we thrive off of a game that is designed just like this one (losing outcome due to rake) but can overcome this disadvantage by making +Ev decisions along the way because while the gaming environment is static (all players lose to the rake) the independent variables found within the game and the variance of them makes this profitable for a percentage of the players, with the “rounds” being equivalent to preflop/flop/turn/river decisions. The expectation changes at each street, but in the end, can be positive for one of the players involved. These types of independent variables means that making the wrong decisions will have different outcomes of Ev, regardless of the game itself, which is how players in both poker and the example game walk away with money.
Hope you all are having a great day!
For me most of the time, my initial decision (intuitive) is often the best so I always end up regretting for picking the other options.... Fml
Very informative, thank you very much!

*Did you thought you make your decisions*? I mean decisions are manifestations of your mind right! *What if i tell you that people think they are their mind, but in reality they are not. First of all you did not choose your mind it is molded by your environment ( parents, friends enzz) and you did not choose that either*. Furthermore your mind is made up out of your genetics, ( you did not choose them) So you are actually responding to a mind that is made by your environment and you never had any free will in that. The question that remains is then who and what are you??? Find out who you really are and how life really works. Google *TruthContest read the Present*, it explains the big picture of life in every facet, it will set you free.

First time I read something from TheTruthContest spamming assholes and it's actually true.
I agree decision by environment, but I think we can change to do what we want.
Muhammad Iqbal it's really REALLY hard
Ben B its only hard if your spirit is weak, which you can strengthen anyway
One problem with the game show example is that it does not account for variance in probability, meaning the choices have the same mean but still quite different. You would take the guaranteed bonus in both examples because they have equal means but less variance in outcome, meaning they are less risky.

''Consider that the intuitive answer might not be the right one after all''
I experienced just the opposite in every single test I took
Does this count as a rash, irrational decision? I quit my job because I was disgusted by my ex-colleague's opinion about a worker who almost passed. To give a fairly quantitative backstory, we took him to her office for a few mistakes he made, involving filter and touching people. He was always a very outgoing, tactile person, so of course, he never _meant_ harm or discomfort, but I was firm with him and told him handshakes and work/school conversations only. I even insensitively said to my ex-colleague "Is there anything you want to add." That night, our worker got into an accident and almost lost his life. It knocked some sense into me and made me realize that I mishandled the situation. When I expressed this to my ex-colleague, she insisted we didn't do anything wrong. As sorry and distraught as she is for his accident, and happy and relieved that he survived, she says it doesn't change her opinion for his "wrongdoing". That we would always be right and he would always be wrong. I decided then that she doesn't care *enough* for our worker--not as much as I did--and I decided I couldn't work with someone like her. What do you guys think? Was that an absurd decision to make? When someone flawed almost goes, you're supposed to appreciate them and maybe even see where _you_ went wrong too. I do now; my ex-colleague doesn't. We never should've taken him to the office. I _alone_ should've spoken to him respectfully in the hall or something. He is not a bad guy or a handsy creep.
