Are you a good thinker - or a poor one? Take a look at the general traits associated with each category and assess yourself. (Remember, a good thinker is willing to be critical about herself!)
The Good Thinker
Welcomes problematic situations and is tolerant of ambiguity.
Is sufficiently self-critical; looks for alternate possibilities and goals; seeks evidence on both sides.
Is reflective and deliberate; searches extensively when appropriate.
Believes in the value of rationality and that thinking can be effective.
The Poor Thinker
Searches for certainty and is intolerant of ambiguity.
Is not self-critical and is satisfied with first attempts.
Is impulsive, gives up prematurely, and is overconfident of the correctness of initial ideas.
Overvalues intuition, denigrates rationality; believes that thinking won't help.
