A new study released in Applied Psychology found that people with a highly rational thinking style actually became more biased as the stakes went up.  The authors suggest that in an escalating situation, the highly analytical thinkers were less able to tune into the dissonance that would cause them to challenge their own assumptions.

In other words:  They ignored the feeling that they were on the wrong track.

The common view is that we need to be rational to make optimal decisions, but it’s just not true.  The last century has been driven by this paradigm and the results are clear – while we have incredible technical excellence, we are failing as a species.  My contention: “Analytical = Better” is one of the most pervasive and destructive myths of our era.

If wisdom is to be found, it is not within the paralyzing prison of logic alone.
