Interrogating association claims means asking three core questions: Were the variables measured well (construct validity)? Can the results be generalized to other populations (external validity)? And is the association statistically strong, significant, and precise (statistical validity)?

The four big validities offer a comprehensive toolkit for evaluating psychological research. Construct validity ensures that variables are accurately measured or manipulated. External validity tells us whether the results generalize. Statistical validity ensures the numbers are trustworthy. Internal validity confirms that cause-and-effect relationships are legitimate.
