The Book Bench: Is Self-Knowledge Overrated? : The New Yorker:
"Nevertheless, there is a subtle optimism lurking in all of Kahneman’s work: it is the hope that self-awareness is a form of salvation, that if we know about our mental mistakes, we can avoid them. One day, we will learn to equally weigh losses and gains; science can help us escape from the cycle of human error. As Kahneman and Tversky noted in the final sentence of their classic 1974 paper, “A better understanding of these heuristics and of the biases to which they lead could improve judgments and decisions in situations of uncertainty.” Unfortunately, such hopes appear to be unfounded. Self-knowledge isn’t a cure for irrationality; even when we know why we stumble, we still find a way to fall."
