It is true that this is pretty much meant to be a populized presentation but I would say it's still quite interesting (at least, for a non-psychologist). It does pack quite alot in a short and entertaining video :)

Also, I don't think Maslow's Heararchy of Needs really explains why people perform worse when they are paid more. According to it, shouldn't paying more just stop making much of a difference after a certain point?
