Thinking or feeling can often be a source of conflict in communication. Both of these behavior preferences describe rational decision-making processes. It is not that thinkers don't have feelings, or that feelers are incapable of logic. It is just that they use very different criteria to make their decisions.

People are different. We think, act, and process information differently from each other. We all know this, but why and how we're different is less obvious. This often results in personality clashes. Our personality type is encoded in our DNA, just like our preference for being either right-handed or left-handed.
