Answer:
Three barriers to critical thinking are group thinking, biased thinking, and arrogance.
Explanation:
Critical thinking can be defined as an intellectual process of judging a piece of information or reaching a conclusion after conceptualizing, applying, analyzing, and evaluating data obtained via observation, communication, reasoning etc. The purpose of critical thinking is to reach a sound conclusion that can be effectively proved true. There can be several barriers to critical thinking. Three of them are group thinking, biased thinking, and arrogance.
Group thinking takes away our individuality, our freedom to think for ourselves. It is the sort of thinking related to stereotypes, for example. One of the biggest issues with group thinking is that we don't even realize we have been conditioned by this societal way of seeing things. Without self-awareness, it becomes harder for us to open our minds to what is new or different.
The same goes for biased thinking. Be it because we were influenced by others, be it because of past experiences, or even because we are prejudiced, biased thinking makes us judgmental and, consequently, less able to think in a new way. Critical thinking does require us to judge, but only after considerable reasoning and evaluation of evidence.
Finally, arrogance makes it practically impossible for us to listen to suggestions. By refusing to listen, we miss out on great chances to learn. Arrogance ends up narrowing the channel through which we allow new information to reach us. The consequence can be the fossilization of our thinking process.
