When we’re in scientist mode, we refuse to let our ideas become ideologies. We don’t start with answers or solutions; we lead with questions and puzzles. We don’t preach from intuition; we teach from evidence. We don’t just have healthy skepticism about other people’s arguments; we dare to disagree with our own arguments.

It requires searching for reasons why we might be wrong — not for reasons why we must be right — and revising our views based on what we learn.

We all have blind spots in our knowledge and opinions. The bad news is that they can leave us blind to our blindness, which gives us false confidence in our judgment and prevents us from rethinking. The good news is that with the right kind of confidence, we can learn to see ourselves more clearly and update our views. In driver’s training we were taught to identify our visual blind spots and eliminate them with the help of mirrors and sensors. In life, since our minds don’t come equipped with those tools, we need to learn to recognize our cognitive blind spots and revise our thinking accordingly.
