Beliefs can have different effects on our mind and body. Some beliefs might be called "constructive" because they help us better adapt to our world, make us feel positive about ourselves, and result in overall better physical and mental health. Some beliefs are "destructive" because they induce stress within us, worsen our health, or create antagonism and violent feelings toward others. One of the most important aspects of why beliefs can be constructive or destructive depends on whether they are exclusionary of other perspectives and how strongly they are held. The data indicate that all beliefs have their limitations because the brain has limitations. Thus, constructive beliefs help provide a sense of compassion for everyone else, who are also relying on their own beliefs—beliefs that also have limitations.
