A new research paper by Thomas Kelly at Princeton University entitled "Disagreement, Dogmatism, and Belief Polarization" published inThe Journal of Philosophy focuses on belief polarization and adds even more insight into how fickle our brains are. Among other things, Kelly points out that the timing of when we learn something matters:
“What I believe depends on the temporal order in which I encounter two opposing pieces of evidence. Thus, I can end up with diametrically opposed views, despite having been exposed to the same evidence. The only difference is the order in which I received it.”
We are much more fallible than we like to believe. As such, we are more likely to come up with viable solutions to persistent societal problems when we have more humility about our own views and more curiosity about opposing ones.
