" The lesson we learn from Nightingale's experience is that, as painful as it may sound, we humans are barely able to reason on our own or when surrounded by like-minded people. When we try to reason this way, we end up rationalizing because we use arguments as self-reinforcing virtue signals. And the worst news is that the more intelligent we are and the more information we have access to, the more successful our rationalizations are. This is in part because we're more aware of what the members of the groups -- political parties, churches, and others -- that we belong to think, and we try to align with them. On the other hand, if you are exposed to an opinion and don't know where the opinion comes from, you're more likely to think about it on its merits. "
