When someone possesses clear thinking, there are opportunities for having more objectivity  (i.e., open-mindedness) to occur.  Suppose this same individual is blessed with intellectual curiosity.  They can think of any number of possibilities in resolving an issue, instead of landing on merely the first thing that comes to mind.  They will exhaust all possibilities until they find the correct one.

Mental health experts with these criteria will become leaders because they have some of the most important qualities imaginable in treating their clientele.
