"People differ in how well they tolerate contradictions and ambiguity, and this personality style likely affects their success at gaining insights. People also differ in how ready they are to entertain ideas that they don’t think are true and in how much they enjoy imagining alternative universes.
Some people become impatient with speculation. They see the playful exploration of ideas as a sign of immaturity. They want closure, and they roll their eyes when a member of the group starts going off on tangents. They are concrete thinkers who just want to work with the facts, not with flights of fancy. This concrete reasoning style wouldn’t leave people very open to insights."
