To neurophysiologists who research cognitive functions, the emotionally driven appear to suffer from cognitive deficits that mimic certain types of brain injuries. Not just partisan political junkies, but ardent sports fans (the Windies are always just around the corner from reclaiming cricket glory), the devout, even hobbyists—- anyone with an intense emotional interest in a subject, loses the ability to observe it objectively. You selectively perceive events. You ignore data and facts that disagree with your main philosophy. Even your memory works to fool you, as you selectively retain what you believe in and subtly mask any memories that might conflict.
Studies have shown that we are actually biased in our visual perception —- literally how we see the world—- because of our belief systems. This cognitive bias is not an occasional problem. It is a systematic source of errors. The third rate mind is only happy when it is thinking with the majority. The second rate mind is only happy when it is thinking with the minority. The first rate mind is only happy when it is thinking.
As humans, those in each category suffer biases, but the first rate thinker is aware of his biases and proceeds accordingly. Until we all become aware of our biases, emotive issues will never be thoroughly resolved.
