Describe how you can know if a theory is valid. What is evidence or data? Where does evidence/data come from? What role does evidence/data play in understanding a theory? Using one of the theories presented in the textbook, describe what sort of data might be useful in testing this theory. How might you collect this data? Note: Do not describe the same sources of data as one of your classmates has done in a previous post. Contrast a theory from a personal belief. What are the practical uses for a theory, and what are the practical uses for beliefs? Which is more likely to represent a bias, a theory or a belief? Using one of the theories presented in the textbook, explain how the theory differs from personal beliefs. Offer examples of personal beliefs that contrast with the components of the theory. Note: Do not use the same beliefs as one of your classmates has used in a previous post.
