In the case of Kitty Genovese, the cons must have outweighed the pros and the witnesses probably thought that if they went out to save her, they might be harmed too, and they feared this. In discussing the advantages and disadvantages of face validity, we distinguish between those scenarios where (a) face validity is the main form of validity that you have used in your research, and where (b) face validity is used as a supplemental form of validity, supporting other types of validity (e.g., construct validity and/or content validity).
