>>As one of my professors used to say, there are two basic types of psychologists - lumpers and splitters. The lumpers try to find the universal principles that apply to all people. The splitters like to focus on differences between people. My guess is that a balance of both approaches is the best way to go. <<
So would this professor's categorization fall into the "lumping" or "splitting" category?
Labels. What would we do without them?
