Question

What is an example of thinking in an exclusive way, which may inhibit the process of intellectual growth and moral development?

Answer 1

Lack of intellectual growth, and moral development? A narcissist examining the world around him. We had that during the last presidential campaign, and it still abounds on Twitter.
That is a perfect example of thinking in an exclusive way.

Answer 2

Just one example: a deeply held belief that only people of white European ancestry are intelligent, as "white supremacists" say they believe. That precludes the idea that people of other ancestry can be of equal value to society and precludes learning anything that contradicts that belief. Any such belief, with no empirical evidence to support it, may preclude learning and moral development. If one believes that thunder is caused by God playing ten-pins, one may not be open to scientific explanations of how thunder occurs.

Answer 3

In criminal justice, a juror who believes all young black men are thugs at heart may prompt the juror to vote to convict even if the defendant probably didn't steal that particular candy bar. He's probably guilty of SOMETHING bad, so lock him up!
