For some reason, i can never sit through the lecture of my professors, i'd either fall asleep or get bored with their analogy and start tapping on my phone but surprisingly I would sit through your videos and just keep replaying it if i dont understand it. Anybody else going through the same thing i am ? I also would come to your videos before going to any of my professors just because you are much more easier to understand.

I'm sure if your professor would have a smartboard, a nice voice, and an easy example you would go to his lectures. We, like people, have changed over the past 20 years or so. Since multimedia became mainstream we changed our attention span and our expectations for entertainment. There have been numerous studies on our attention span. One showed that, because of cell phones (social media scrolling), our attention span has significantly decreased, which means we 'can' only comprehend something for a short time before getting bored and 'scrolling away'. Another thing is, we get bored by plain text, plain speech, etc. One of many studies showed that the same post (same text, same information) gets less attention (fewer likes and comments) on Facebook if it's only in plain text instead of a text and picture (without taking into account how related the picture is). I see asynchronous learning (videos) as the future of learning because you have a multimedia format (speech + pictures, graphics, videos) with enriches the experience (most of us are visual types, hence it helps us to understand something when it's already visualized) and helps remembering stuff (there's been a psychology experiment I think in the '80s where they tested short-term memorization of words by just reading them and a technique that uses non-related visuals, i.e. for each word you look at an object in your surrounding), and you also have the options to replay the video or pause it as you like, in that way dictating your own learning tempo.

The confession/confession scenario is very very very stable

Both deny is the state of " Pareto Optimality".

Funny thing no prisoner considered a possibility that the offer was a lie...

Now education is truly free thanks to Khan Academy

Are there any universal techniques to detect these in games? I guess they will be quite obvious alot of the times, even moreso when you're good at the game, but it's hard to be good at a game still in developement.. I'm going to say the answer is probably no, and that I just need to get together some minds and do a huge load of testing.. And if they're problematic in the sense that they reduce the amount of viable decisions into a linear period of decision making, fixing them would perhaps be even harder..

being a good DA is being a good hustler.

Darn that spelling mistake. "Equibrium."

3 years in prison with a reputation as a snitch is greater than 10 years in prison as somebody who got snitched on.

Finally it clicked 🙏 khan academy never disappoints

This is off topic but I wonder if queuing (standing in line), where the serving time is proportional to (say) numbers of checkout items, could be treated by economic analysis in some way. While "first come first served" is fair (and upholds trust etc) there is the collective waiting time of for the people behind first place. People can switch in pairs, you see. So how could the line move to towards an 'optimal' arrangement under this type of approach?

❤ thankyou sir

thanks a lot for the wonderful explanation sir. Love from India :)

Does this break down if for example the equilibrium state is 6 years instead of 3?

the fact that sal addresses both the culprits who were caught red handed selling drugs as gentlemen is just hilarious!

What about the added idea that the guy serving 1 year will probably get shanked and die for dropping a dime on his buddy?

Its a shank or get shanked world out there. Shank the shanker to not get shanked. Dont shank the shanker, get shanked. Before yk it there will be piles of shanked bodies.

Good explanation. Only thing I'd say is that the risk of not confessing in this case is so much greater (8 more years in prison) and reward of not confessing (just 1 year less in prison) make it a no brainer to confess. If the reward for both not confessing was greater (say 5 less years of prison) then it would be more tempting to take the risk and not confess. But the point of the video is to explain how the game theory works...which he successfully does

So Henry pretty much used this scenario in snitching and confessing in GoodFellas?

thought this is a bit familiar and realized how watching Running Man for all those years helps me understand this more quickly. lol their loyalty test episodes are somehow like this 🤣

As they say in the streets, snitches get stitches, and homies don't rat out homies. Prisoner's Dilemma doesn't work when there is loyalty amongst the thieves.

I have introduced several thousands students to this theory and through social action prepared them for real life. As you can imagine in short run dishonest win, in long run honest ones. In fact 85% explain moral capital and firms and countries who play fair are winners. So God does control output, money is pure reflection of moral, intellectual, and social economy.

i searched long and hard for this comment

ive either thought about this equilibrium too much... or i was accidentally thrown into a parallel universe where everyone and everything part takes in a weird, oddly saddistic thought experiment with no end 😬 i suppose it is possible that the nash equilibrium itself, as a topic, causes symptoms of the disease suffered by dr nash himself.

Dear Sir Kahn, I worship you, I really do, and I never thought I‘d see you giving a flawed explanation but today is the day. :-( The way you explain it, it‘s mixing up the concept of „dominant strategies“ and „Nash equilibria“, which might be very confusing to students. In this special case of the prisoners dilemma, the state „confess/confess“ is both: an overlapping of the two dominant strategies „confess“ AND a Nash equilibrium (because the overlap of dominant strategies is ALWAYS also a Nash equilibrium), BUT a Nash equilibrium can perfectly exist without dominant strategies being around. They way you explain and derive it in the beginning, it seems that „confess/confess“ is a Nash equilibrium because it’s the overlap of the two dominant strategies „confess“, but the real reason why „confess/confess“ is a Nash equilibrium, the very core concept of the Nash equilibrium, is only what you start to explain at around 7:50. So to every student who reads this: Don’t confuse these two concepts! Greetings from a former RWTH Aachen Tutor.

Both individuals, acting as rational decision-makers, opt for the less risky choice of confessing, given that the risk associated with denial is greater for both of them. In other words, they both select the three-year option due to its lower risk.

Hi Em

This is in reference to oligopoly collusion right?

Why do you frequently repeat your words right after saying them?

It's about risk. Ratting out the other guy limits your risk from 5x to just 1.5x. It's a very good tradeoff given the potential risk.

Well, what about the state classification of “snitch” where it doesn’t matter how many years you’ll be in prison because you’ll be dead. Interesting concept though

Awesome dilemma but confessing to an armed robbery that doesn't exactly look too good once you're out. Well, neither does doing 10 years for drug charges lol

I understand this in the way of explaining Nash equilibrium, but from a law enforcement perspective how does choosing the "optimal" outcome from the prisoners' perspective (both confess) accomplish justice if the prosecutor was, in fact, wrong about his assumption in the first place about the other crime in question? He would have just gotten 2 men to confess to another crime they weren't guilty of and the real criminals get off scot-free. I guess it's proving that the Nash equilibrium actually pans out further than calculated? It certainly isn't good law enforcement, in fact, in many ways they've actually made things worse - justice was perverted in the case of 4 people (2 got away with it completely, 1 got a reduced sentence for lying, and 1 got an increased sentence for telling the truth!). I think it would be good to present a caveat to this illustration in advance!

Al got red handed selling drugs, hahahaha

"A beautiful mind" brought me here

There's no need to repeat things as you write them. There's no need... to repeat things.... as you write them...

love this dilemma, and beautifully explained. but if i was the guy trying to get them to confess i wouldn't give this test, since what if they didn't do the crime? by this logic, maybe they'd still both confess! so if they actually did commit the crime, and they both confess to it, i still wouldn't know if they had done it or not!
