Nietzsche

I’m not sure how to write this so as not to be unpleasant, but Nietzsche was right. Yeah, he had a weird mustachehe was loaded with opium and loved to take long walks in the Alps; but he was right. At least when it comes to one of his most apparently innocuous, but most radical ideas: that it often doesn’t matter if someone is right or wrong, that we make the decision to agree with them beforehand, that what matters most to us is the tone, the forms. The rest, although it doesn’t hurt to admit it, doesn’t matter. 150 years after Nietzsche, cognitive science has proven him right. What did Nietzsche mean…? In 1878, in the midst of a break with Wagner and Schopenhauer, Friedrich Nietzsche published ‘Human, too human‘. It was his first book of aphorisms and in it he abandons romantic aesthetics and sets out to find a new way of observing the world. In that book, the Austrian philosopher makes a complete x-ray of the psychological junk of human beings. “Opinions are born from passions,” he says in aphorism 637. “Convictions are more dangerous enemies of the truth than lies,” he writes in 483. But the one that interests us is 303. Where Nietzsche discovered confirmation bias. “Often, we contradict an opinion when in reality what we find unpleasant is only the tone in which it was expressed,” says that aphorism. And that sounds a lot like what modern cognitive science calls ‘confirmation bias‘: the tendency to search for, interpret and remember information in such a way that pre-existing beliefs, expectations or hypotheses are reinforced. First we form an idea from the tone of the person speaking to us and then we justify it. Simple, clean and perfectly confirmed by the evidence. Ultimately, what Nietzsche did is anticipate many of the ideas that Kahneman and Tversky They earned him the Nobel Prize. But that matters little, what matters is what we can learn. And, under that sullen and savage reputation, Nietzsche has a lot of useful ideas. This intuition, without going any further, has a direct and everyday application: when someone addresses us with a tone that we perceive as aggressive, condescending or arrogant, our brain activates defense mechanisms that prevent us from rationally processing the content. We do not evaluate what they tell us, we evaluate how they tell us. Reactanceconfirmation bias and post-hoc rationalization: the perfect combo to act automatically without paying attention to reasons or consequences. In the same way, Nietzschenian reflection helps us think about how we address others. And that is worth it.
