The mother of all misconceptions is the confirmation bias. What is confirmation bias?
Confirmation bias is the tendency to interpret all new information in such a way that it is compatible with our existing beliefs. It is the filtering out of information that contradicts our existing beliefs, assumptions and theories.
Imagine that you contact the Corona virus and become infected with Covid 19. You have to attend an interview, but since you are sick you cannot go for the interview. If you are an atheist, you might interpret this as an example of the randomness of life, a proof that there is not intelligent being or God controlling man’s life. However, if you are a theist, you might say that you were likely to do badly in the interview and God saved you from the embarrassment of doing badly at interview. Such is confirmation bias
