Critical Thinking is a Path of Honesty. It requires a commitment to integrity in how we acquire, evaluate, and make use of knowledge and exploration. Engaging in critical thinking allows us to reduce the probability that our egos will distort our interpretations and create a fantasy world for us to live in - mentally.
In contrast, avoidance of critical thinking assures that our interpretations about "reality" can never be effectively countered or dismissed, since it refuses to allow contrary positions to be seriously considered or to allow evidence to be carefully analyzed and evaluated.
So if critical thinking is a path of honesty, then denial of critical thinking must surely represent a path of dishonesty.
