What is the difference between scientists and the rest of us? Scientists have perennial skepticism about reality, and only give their credence to what can be proven with verifiable tests. The ultimate goal is the discovery of what is true — and true beyond any doubt. They are reality seekers.
Compare that to the rest of us relative to “reality”. The rest of us tend to believe what we want to believe — whatever supports our inclinations, biases, predispositions. We tend to believe facts that support our preferences even if those facts are in all probability flat out wrong. Conversely, we tend to deny facts that in any way contradict our preferences even if those facts are in all probability correct.
So how do these two orientations differ? Scientists seek truth; the rest of us seek self-justification.
