It set up a false dichotomy between being abusive to students in order to achieve excellence and softballing them with praise so they'll never work hard. Most people I've talked to bought into this dichotomy after watching this movie, thinking that there is some kind of tradeoff between greatness and abusiveness. The movie legitimizes this false dichotomy, not by condoning the abuse, but by implying that it is the unfortunate price of greatness. Whether or not this was the intended message, it seems to have been the message that most people I've talked to have internalized from it.
Interesting. My thoughts were this was the weak half-rationalisations of a teacher taking out his anger at himself for his own career having plateaued on his students. I think that's a shame that just because the film doesn't explicitly criticise this viewpoint (apart from through the whole narrative of course -- he ends up dropping out of school when he could've been happy being a good gigging musician with a girlfriend -- and someone commits suicide) people internalize it. See Fight Club I guess.

It seems especially egregious in creative fields. It might be good for muscle memory, I suppose, so perhaps it applies to drumming. But horrible for the hard creative problems which would include many aspects of music.
I do think the movie is ambiguous though. Watching it again, I started to wonder if the ending isn't just a fantasy of Andrew as he stares up at Carnegie Hall.
While you are right it is a false dichotomy. It isn't completely made up either. Greatness can (often) be achieved through abusively pushing someone to their limits... Like most elite sports athletes...
Daniel Kahneman (from his autobiography, but he tells the same story in Thinking, Fast And Slow):
> I had the most satisfying Eureka experience of my career while attempting to teach flight instructors that praise is more effective than punishment for promoting skill-learning. When I had finished my enthusiastic speech, one of the most seasoned instructors in the audience raised his hand and made his own short speech, which began by conceding that positive reinforcement might be good for the birds, but went on to deny that it was optimal for flight cadets. He said, “On many occasions I have praised flight cadets for clean execution of some aerobatic maneuver, and in general when they try it again, they do worse. On the other hand, I have often screamed at cadets for bad execution, and in general they do better the next time. So please don’t tell us that reinforcement works and punishment does not, because the opposite is the case.” This was a joyous moment, in which I understood an important truth about the world: because we tend to reward others when they do well and punish them when they do badly, and because there is regression to the mean, it is part of the human condition that we are statistically punished for rewarding others and rewarded for punishing them. I immediately arranged a demonstration in which each participant tossed two coins at a target behind his back, without any feedback. We measured the distances from the target and could see that those who had done best the first time had mostly deteriorated on their second try, and vice versa. But I knew that this demonstration would not undo the effects of lifelong exposure to a perverse contingency.
First, the demonstration Kahneman arranged is simply a demonstration of regression to the mean and is not evidence of the validity of his hypothesis.
Is the hypothesis itself wrong? We can test the validity of the hypothesis on all people by testing it on a subset: teachers with expertise in the subject they are teaching. Kahneman hypothesis implies that such teachers reward students only when their level of achievement is higher than it has ever been in the past and punish them whenever their achievement is below their highest level of achievement.
This does not hold true in my experience of my own teachers. I was occasionally praised for doing well or punished (in some sense) for doing badly but much more often when I spoke with my teachers they remembered trends: I started bad and got better slowly, I started off well but seemed to get lazy, etc.
In my experience teaching first year math courses I would only automatically remember individual achievements if they were very surprising. For example, a student who was failing suddenly moving into the top of the class on a test.
I think people have a natural tendency to focus on these kind of outlying events and assign them special significance that they may not actually have. Although Kahneman does not mention this tendency his hypothesis suggests he also believes this.
But compared to the interesting outlying events the vast majority of student's achievements are not memorable. This means a teacher will not automatically remember them. If the teacher does not choose to remember them then they will be forgotten.
Since a teacher's capacity to remember is limited, trying to remember all student's achievements or failures was low on my priority list. Knowing a student's general trajectory lets you tailor your approach when working with them on a problem whereas individual achievements or failures are usually just noise. Other teachers I knew seemed to feel the same way.
Of course my own experience is only a data point against Kaneman's hypothesis about people in general. I am sure there could be types of teaching environments where something like what he is suggesting could be true. If the performance of the students on a particular test were tied to the teacher's compensation or the opinion of people they respect or who have power over them then I can see how a student's performance on that test would get highest priority in a teacher's mind and this could lead to reactions of the kind Kaneman describes.
> Kahneman hypothesis implies that such teachers reward students only when their level of achievement is higher than it has ever been in the past and punish them whenever their achievement is below their highest level of achievement.
Not really, Kahneman is talking about doing better or worse than expected, not about your best or worst performance.
Regression to the mean arises when following up on any deviation from the mean – though of course the more extreme the deviation, the more pronounced the effect.
Similarly, the effect of regression to the mean is smaller when measuring longer periods of time (less measurement error means fewer fluke outcomes) but it doesn't disappear.
Of course, it's perfectly possible that strict teachers are truly beneficial even when accounting for regression to the mean, it doesn't have to be one or the other, and Kahneman certainly doesn't prove anything of the sort, but it does shift back the burden of proof to those who would claim that strict or even borderline abusive teaching is helpful.
> Not really, Kahneman is talking about doing better or worse than expected, not about your best or worst performance.
At a given point in time there are two quantities we need to worry about: how the teacher expects the student to perform at that point in time and the student's ability to perform at that point in time.
If the teacher is rational and has seen the student perform many times these quantities will be the same. I think the outcome is probably optimized if these quantities are the same at all times but in the real world there may large disparities in the values which can fluctuate over time.
Nevertheless, suppose it were the case that the values are always equal. Then Kahneman's hypothesis is obviously wrong. The student will perform better than expected roughly the same number of times they perform worse than expected (in the long run, obviously).
Regression to the mean exists, yes, but has no impact on the distribution of the events of being above the mean or below the mean.
I supposed that Kahneman would recognize this fact and he his reference to regression to the mean was based on a more complicated but much more realistic model where the expectation is not always aligned with reality. In such a model there must be a mechanism for relating the two quantities after each new performance/test/review.
I tried to think of how this model would work and suggested Kahneman meant that expectations were adjusted based on previous best values. I should have been clearer that other mechanisms were possible and that I was only guessing which Kahneman meant. Then I argued that based on my experience this is a poor model of how teachers punish/reward their students in general because it is unnatural and unhelpful to the task at hand. As this model is not valid his conclusion that people are incentivized to punish each other is specious.
You would like Frank Herbert's books: Dune, Dosadi... It's weird how most of his books have as a common element exactly that: suffering leads to greatness (the Fremen, Sardaukar in Dune, as well as the introductory Gom Jabar, the Dosadi people in Dosadi, etc...)
And for what it's worth, I personally think you are way off. Most of the time, abuse/suffering leads to stunted growth and/or trauma. Very few transcend that. I think you've got confirmation bias (as I once had).
Many examples would prove you right, but I can't help thinking it would be better to fuel someone's desire for excellence instead of abusively pushing him.
Counter example would be Marion Bartoli who won wimbledon against all odds and her own limits, pushed by her father, then immediately stopped being a professional tennis player. Too many sacrifices. Pretty common in women pro tennis.
And there was also the case of Argentinian footballer Gabriel Omar Batistuta, one of the greatest strikers of all times, who had this to say about the time which followed the end of his career:
> "I left football and overnight I could not walk anymore. In two days I could not walk...I peed in the bed, the bathroom was 3 meters away, because I did not want to get up. It was 4 am and I knew as soon as I stood my ankle would kill me. (... ) "I went to see the doctor (specialist in Orthopaedics and trauma) Avanzi and told him to cut off my legs. He looked at me and he said I was crazy. I insisted. I couldn't bare it any longer. I can't explain to people how bad the pain was," he said
I really liked the player when I was a a teen, I would always pick the Fiorentina in FIFA games to play with him. Overmedication (if not worse) so that he can always be on the field has put him in this condition. Very sad. But I read he feels better with his legs now.
There's no point to doing that. He can't step down or be removed as the inventor of javascript, but he could step down or be removed as CEO of Mozilla.
This is really cool. I could see another application for it - Teachers delivering music lessons to students. As a drum teacher this would be a perfect platform for me to deliver my lessons, assuming you could support drum music (but there's probably a market for this among guitar tutors). I'm imagining a billing system where students pay to subscribe to my lessons and you guys take a slice of the pie.
Thanks. We're definitely interested in making something for music teachers. I teach gypsy-jazz guitar at the Old Town School of Folk Music in Chicago, and I've used Soundslice with my students a teeny bit but so much more is possible.
Could you and I connect via email so that I can get more thoughts? Contact info in my profile.
As the director a development agency, we cannot use Shopify for our clients until they create the ability for products to have custom fields. Some products need to present more information than is standard, such as a wine store that needs to display vintage, alcohol. volume etc. Til then this excellent new technology is useless to us.
Unless I've missed it, there isn't a way to cleanly add meta fields to the admin backend for products. It has to be done via an app, which means data entry needs to be split between built-in Shopify fields and meta fields via a Shopify app interface on a different screen.
Midi is hardly appropriate or useful for music engraving. It's for controlling a device to output music in the way you want, not for recording how it looks on paper.
I'm on the first chapter, but I can tell this is the perfect book for me. Very well written. Easy to follow for a non-mathematician and overall, a perfect introduction to a field I'm very interested in learning. I've worked through books such Programming Collective Intelligence but this closes the gap between blindly following along and actually understanding the fundamentals which that book lacks.
There are some blatant ripoffs amongst the list of links in the post, but I think you should remove the last two. Pearl web studio and the germ one are far from ripoffs of your site.
If Elon Musk achieves everything he has set out to do, his name will surely be etched into the history books. And, it seems, those history books will be read by humans further into the future than perhaps otherwise, BECAUSE his name is in them.
This simplifies the process even further than typical midi editors do - lowering the barrier to entry for creating music.
But as a professional drummer and tutor, a tool like this could seriously help me, if you decide to expand the feature set beyond a novelty. For example, this could be a way for me to take notes of drum beats that come to me when I'm not at the kit, if it supported tuplets.
