From what I can tell, most people are stuck in a developmental stage prior to critical thinking, where
social and psychological factors are the ultimate reason for their ideas. Gaining popularity and social acceptance are usually higher goals than figuring out the truth, especially if the truth is unpopular. Therefore, the real causes for error are often socio-psychological, not intellectual—an absence of reasoning rather than a mistake of reasoning. Before reaching the stage of true critical thinking, most people’s thought processes are stunted by issues like insecurity, jealousy, fear, arrogance, groupthink, and cowardice. It takes a large, never-ending commitment to self-development to combat these flaws.
