- “Although you should be careful not to commit the ecological fallacy, don’t let these warnings lead you into committing what we might call the individualistic fallacy. Some people who approach social research for the first time have trouble reconciling general patterns of attitudes and actions with individual exceptions. But generalizations and probabilistic statements are not invalidated by such exceptions. Your knowing a rich Democrat, for example, doesn’t deny the fact that most rich people vote Republican—as a general pattern. Similarly, if you know someone who has gotten rich without any formal education, that doesn’t deny the general pattern of higher education relating to higher income” (Babbie 2011:108).
