Thinking critically about theories in psychology -- "We want theories that help us make sense of the world through helping us make sense of data we can collect about that world. Theories that can do this for us are likely to be complete, concise, clear, coherent, consistent, testable, supported and thought-provoking. In other words they should meet the standards implied by the criteria of comprehensiveness, parsimony, clarity of constructs, internal consistency, testability, empirical support and heuristic value." (Comment: I wish they wrote this in plain English)
