...we’re all less conscious of our severe mental shortcomings and less inclined to be skeptical of our own opinions. ... We have confirmation bias; we pick out evidence that supports our views. We are cognitive misers; we try to think as little as possible. We are herd thinkers and conform our perceptions to fit in with the group....the culture places less emphasis on the need to struggle against one’s own mental feebleness. Today’s culture is better in most ways, but in this way it is worse.
...There’s a seller’s market in ideologies that gives people a chance to feel victimized. There’s a rigidity to political debate. Issues like tax cuts and the size of government, which should be shaped by circumstances (often it’s good to cut taxes; sometimes it’s necessary to raise them), are now treated as inflexible tests of tribal purity.
...To use a fancy word, there’s a metacognition deficit. Very few in public life habitually step back and think about the weakness in their own thinking and what they should do to compensate.... Of the problems that afflict the country, this is the underlying one.
Amen, my brother. You're preaching to the choir here.
