Wisdom Of The Week

It’s impossible to overstate the influence of Kahneman and Tversky. Like Darwin, they helped to dismantle a longstanding myth of human exceptionalism. Although we’d always seen ourselves as rational creatures—this was our Promethean gift—it turns out that human reason is rather feeble, easily overwhelmed by ancient instincts and lazy biases. The mind is a deeply flawed machine.

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.

This same theme applies to practically all of our thinking errors: self-knowledge is surprisingly useless. Teaching people about the hazards of multitasking doesn’t lead to less texting in the car; learning about the weakness of the will doesn’t increase the success of diets; knowing that most people are overconfident about the future doesn’t make us more realistic. The problem isn’t that we’re stupid—it’s that we’re so damn stubborn.

Kahneman, of course, knows all this. One of the most refreshing things about “Thinking, Fast and Slow” is his deep sense of modesty: he is that rare guru who doesn’t promise to change your life. In fact, Kahneman admits that his decades of groundbreaking research have failed to significantly improve his own mental performance. “My intuitive thinking is just as prone to overconfidence, extreme predictions, and the planning fallacy”—a tendency to underestimate how long it will take to complete a task—“as it was before I made a study of these issues,” he writes. As a result, his goals for his work are charmingly narrow: he merely hopes to “enrich the vocabulary that people use” when they talk about the mind.

Over the past few years, Kahneman and work of others has deep influenced how I look at myself and fellow human animals. I am not sure  if it has made me a better person but I think, I have become more conscientious on how I judge myself and others. It's a simple trick Max taught me - stop judging.
