The relationship has to be non-spurious. For example, hot temperatures cause an increase in rape and ice cream sales, so that it is clearly false to say that consumption of ice cream increases rape. Correlation does not prove causation. Drop concepts that are not important, given the empirical evidence. Look at your causal diagram and check to see if there are any logical relationships that have been left out.
Perspectives are general schools of thought, starting out with basic assumptions about human nature.
They are not testable. A perspective is a way of seeing or looking through certain social lenses into the social world. This means that different perspectives provide different visions of social life. So perspectives are intellectual paradigms. They are socially constructed categories of thought through which facts are processed.
