Most of the polarization of our time is due to people's failure to direct their skepticism inward. Skepticism is associated with strength of mind--an ability to resist and scrutinize what others accept as true. But people who claim, for instance, to be climate skeptics are merely pretending to be tough minded, because they practice one-way skepticism, aiming it all outward. True skepticism, the kind that demonstrates strength of mind, is directed inward as well. The current president is an extreme example of directing criticism outwards but none inward. He's tough on others, soft on self. Scientists have an incentive to practice two-way skepticism, because the rigor of their profession requires that they look for flaws in their own data and conclusions, lest they later be discredited by their peers. They have to be tough on themselves, as well as others.
