Ge*****:

That distribution at 2:18 was drawn brilliantly

Sh***********:

2:20 That's a nicely drawn curve, Derek. Well done.

Bo****:

2:54 I feel like that "Yes!" wasn't acting, I bet he screwed up a few times and was getting frustrated lol

Mi****:

0:53 THE SIDEWAYS X OMG I'M DONE (i'm dying laughing)

Vl***********:

wow, that horizontal bar graph at 1:18 looked fancy as f

Al*******:

2:13 Question #1 was really, really, really, really unfair.

Al***********:

2:52 In that "YES!!1" I can hear the essence of frustration of many attempts to shoot that scene. :D

Bh****************:

2:22

The investment in speed cameras HAS paid off. The Aus govt at least, makes millions from them.

Ar*********:

I think Derek has the ability to clearly explain concepts better than either Neil Degrasse Tyson or Brian Cox.  That is SUCH a valuable ability.

I don't wanna request something too significant but... Hey Derek... can you post lectures of you explaining every bachelor/master concept in every STEM field of study?  It'll take you like at MOST 40 years.  O_o  We could do away with colleges and universities then and just direct everyone to your lectures.  XD

ch******:

I have to say constructional feedback is the best I hate when teachers give me an a- without explaining why it's not an a+ just because they say there is room of improvement or it's a way so I would keep try harder. It's better to actually know what I did wrong and how it can improve.

se*******:

One of your better videos
It is unfortunate that your next likely will not be as good.

Lo**********:

For me, negative feedback can really demoralize me over time. For the first or second times, it can make me feel like I'm proving them wrong and I do better, but after too long I just shut down and say "I don't need to please this person" and end up not wanting to do anything they say.

On the other hand, sometimes with positive feedback I know I'll have to up my game to impress again, so I'll try to do so. Of course eventually that becomes difficult and I level off again to reestablish myself before trying again.

Both forms of feedback are beneficial for me in small amounts. Too much negative and I'm less likely to complete the task in the first place, too much positive and I know I can't always do better.

Ci****:

as a highschool student i can tell you now that we tend to do better if promised a reward

G*:

I think you have to consider the circumstances. For instance, the Israeli pilots got reprimanded by authority. The military is no joke. When you get into trouble in the military, it gets scary, and there are potentially big consequences. But if they performed very well and were praised, that doesn't mean the praise made them do worse. It means that they actually did very well that time. I'd say an excellent performance doesn't happen very often in something as complicated as piloting in the military, so it was unlikely the pilot was going to do as well or better the next time regardless of reinforcement method. And when you apply this to a bunch of kids in school, it makes sense too. Getting scalded for doing poorly reflects bad on self-esteem and stirs emotions likely in a negative way. The consequences for not doing superb are far less than if they were a pilot in the military. Positive reinforcement obviously stirs positive emotion and confidence, thus the student performed better overall with that kind of reinforcement. And like you said, culture could in fact have a role. But I doubt it's a heavy role. Human nature is the biggest player in this game. That's my two cents...

Ch******************:

IMHO there are two kinds of feedbacks. Negative: 1) you failed this time. 2) you are a failure. Positive: 2) you did well this time. 2) You are  a winner. It is very important if the feedback is about a particular performance or about the person in general. If it is about the person in general, negative will eventually lead to trauma and positive eventually to arrogance. If it is about a particular performance it still depends on the "undertone": negative can mean "you can/should do better next time" and positive can mean "keep it up" or "you just were lucky". I'm afraid that whole feedback thing is way, way more complex. Just my humble opinion.

el********:

I actually would give 2-3 things that were bad and 2-3 things that were good. This makes the person feel like I am not BS-ing them by only telling the good parts while also keeping high expectations by showing areas that need improvement... anyway, that is my 2 cents.

th***************:

However, excessive praise may cause overconfidence, which can cause a subject to perform using less effort. Might play a role, but regression to the mean is probably the more logical and consistent answer.

je***********:

I hope the correct answer for the question "There are 6 continents on earth" was TRUE.
The question doesn't ask if there are only or exactly 6 continents.

Da*********:

This was such a serious lecture. Congrats for the work done

Ma*******:

And this is why you don't let army training officers of all people think about stuff like psychology.

co******:

this just blew my mind! Damn, applied mathematics are always awesome!

Al*********:

Explained perfectly

However, when i get a bad grade usually i lose motivation whereas if i get an A or 100% i will be more motivated to study harder.

Da**********:

This idea was expressed as “the law of averages catching up with you” when I was growing up.

Sa********:

When I have a bad day at work, I stop being nice and I reg r e s s t o M E A N

Sh***********:

An important video for people currently in university or otherwise writing scientific papers. You'll understand why when you watch it.

Also when it comes to positive vs negative feedback to students and players, keeping someone's attitude and outlook on life feels more important than rubbing in their performance on previous tasks(both positively and negatively).

fa****:

The difference between Regression to the Mean and the Gambler's Fallacy is sample size. In GF, it's only one random event, so the probability isn't changed between the past and present. But in RM, it's a collection of random events. So while one event isn't dependent on it's past, it IS dependent on the average performance of the present, because the probability will be that it is in the middle, regardless of where it was before.

Wi***************:

both positive and negative feedback work.  it's not a matter of which is better, they BOTH should be used for maximum effect.  punishing failure in addition to rewarding success provides a better gain than simply rewarding alone

bl*************:

I believe that the only thing learned through reward is how to get a reward.

I suppose it's all about what we are learning as well. When we learn not to do something, it is usually through negative re-enforcement and the opposite through positive re-enforcement. However there are so many variables that it becomes hazy to know when negative or positive re-enforcement should be used for improvement. 

It is also expected that by using both, eventually an equilibrium is created and each persons equilibrium can be different and can change from time to time, that equilibrium being the point where one is content with oneself at the moment where one doesn't feel the need or expect a reward for learning something, and is also aware of possible consequences which is reward in itself, because one then avoids that which may cause harm, be it mental, physical, or psychological.

I realise as well, that those who always seek reward tend to be self-centered, and greedy and often are not aware of or care for consequences resulting in their need for reward. These people I believe to have great difficulty with the negative aspect of learning and have emotional imbalances.

When I became aware of this subject, it was hard not to notice it, see it in action and the results created, in my workplace and with the daily interaction of people. This also allowed me to know each persons state of equilibrium and the amount of balance or imbalance, and how it affects the person which in turn seems to effect  their personality traits and reveals the level of aptitude they may have.

Ar**********:

It would have been so much better if everyone understood this. I've been thinking about this for a while and tried to explain it my acquaintances, but you can't change that in a day. Thank you for making the first steps to bringing that understanding to the majorities.

A lot of people think that a 50% change of getting head or tails means that if you flip a coin 100 times it would result in 50 heads and 50 tails, but in practice that is not exactly true. There is even a small change that all of 100 flips it will result in only one of conditions.

As they say - there is a big lie, a small lie and statistics. And true and at the same tame false this statement is.

Pl******************:

how about instead caring about other peoples feedback in a positive or negative outlook, you look at things in a realistic outlook. I get annoyed at people who say just be positive... I say, just be realistic. If you did poorly on something, admit your faults, take notice of them and try to improve. Also take note of what you did well, use it for inspiration. Who cares if someone says you did poorly or if you did well... just take note of what they say and improve no matter what.  People telling me how i did on something doesn't effect my performance, practice does.  Think for yourself and questions like these are irrelevant.

Da*******:

One thing that could also influence the effectiveness of of positive/negative feedback is the personality of the people involved.

For example, fighter pilots tend to be super alpha males with big chips on their shoulders.  Positive reinforcement may not have much effect on them as they already view themselves in a very positive light.  Getting them to change via smacking them down a peg or two may in fact be what works better.

On the other hand, using boot camp techniques on a bunch of grandmas in a yoga class is probably not going to have a very good result.

Ak*****:

6:57 One of the best books I've read.

Mi****:

"'This statement is a lie." T/F?" AHHHHHHAAA YOU UNDERSTAND MY SENSE OF HUMOR LIKE NO ONE ELSE OKAY OMG

57******:

The main problem is that they did not pick groups that performed equally well.

You pick a quarter of the them (from the middle) and highlight their good and bad parts, and then see what happens.

Since skill is a large part in how well you perform, if you only praise those that perform the best, and berate those that perform poorly, you will exaggerate the differences, teching the lesser good players they are helpless, useless etc, and raising the better players ego to a point where they are still better, but not as good as they could be.

Hi***:

Wonderful video, wonderful.
As a parent of an autistic child, I struggled with this scenario and could have used this knowledge decades ago when she was young.
Being a communications disease with many a spectrum under it's umbrella, autism tests the parent's ability to dole out any lessons in cause and effect to the more severe of it's victims. I went from both ends of the range on positive and negative reinforcement over the years attempting to teach my daughter some sort of social cohesiveness- at no point, or at any time in all those years (she is now grown and struggling as an adult) did I ever feel as if either option offered any progress.
I came to the conclusion that ultimately, negative reinforcement is far more draining, exhaustive, and generally debilitating to all parties involved, and especially to those souls who live and are part of the fringe and outer circles of that relationship. Negativity breeds a dark environment where at the very least, positivity shines a little light on an otherwise cumbersome day.

ma***********:

I was in a set cohort in college, so all students shared the same classes. We had a teacher break down in class and asked us why everyone was doing so poorly and spending so little time on the assignments. We had to explain to her that we had literally too much work between our other 4 classes per day to accomplish all assignments, and she was the least scary of all the teachers. The negative feedback from the other teachers enhanced our prioritization of their assignments and our commitment to their classes. No amount of positive feedback from the first teacher would have change this.

Jy****:

I think I ran to this on my hobby project doing player performance analysis. I was comparing the players’ performance in a vehicle to the average of their similar vehicles. Initially I excluded the vehicle itself as it seemed logical. But the algorithm worked better (more reasonable results) when I added the vehicle back into the comparison point. It only occurred to me after this video that the unexpected behavior of the algorithm was probably due to the regression to the mean. Since the “player’s other vehicles” dataset was not that large, likely those players who did very poorly on average in the other vehicles, did better in the vehicle being compared to.
