The premise of this book is that it is easier to recognize other people's mistakes than your own.

Psychologists really aim to be scientists, white-coat stuff, with elaborate statistics, running experiments.

Some achieve a reputation for great successes when in fact all they have done is take chances that reasonable people wouldn't take.

It doesn't take many observations to think you've spotted a trend, and it's probably not a trend at all.

If people do not know what is going to make them better off or give them pleasure, then the idea that you can trust people to do what will give them pleasure becomes questionable.

Hindsight bias makes surprises vanish.

Friends are sometimes a big help when they share your feelings. In the context of decisions, the friends who will serve you best are those who understand your feelings but are not overly impressed by them.
