" Remember the three-brain model I talked about earlier—mammal brain on top of reptile brain and human brain on top of mammal brain, with each one building on the one that came earlier in evolution? The instant judgments we make about people are similar, because they too build on the past. That doesn’t mean they’re entirely wrong. (In fact, an initial “gut instinct” is often spot-on.) But it means they’re not entirely right, either. "
