Cognitive limitations

Cbristina Sommers on the limits of reason:

I only recently came to appreciate the limited power of logic, reason and evidence to change minds. Most of us, whether we know it or not, are driven by emotion and group loyalty. Cognitive scientists have long known about a phenomenon called “motivated reasoning”—we tend to use logic and reason, not to discover what we believe, but to confirm what we already think we know. Instead of changing our minds in the face of contradictory evidence, we are more likely to seize on rationalizations for what we already believe. I see this tendency in myself once in a while and try mightily to resist it.
