Explanation:

In psychology, the theory is a principle that explains and solves a problem. Theories always represent a bunch of issues. For example, a theory of evolution explains where humans came and how they survive. But now these days theory has been used for an unsupported claim for example parents claim that for children that you hide last night from home. So it is a little bit confusion in scientific terms. But the scientific theory has a backup with much empirical research. But many people confused with scientific research because scientific theories called theories instead of facts and law. It is because scientific law categorizes and explains a phenomenon. For example, Kapler's law that how the earth revolves around the sun. Many theories accepted about human behavior which are widely accepted such as Sigmund Freud personality theories.
