Dionysians and Apollonians.
There are two sorts of scientists: Dionysians, who rely on intuition, and Apollonians, who are more systematic. Self-experimentation is a Dionysian approach that is likely to open new lines of research. Unfortunately, the Dionysian approach does not allow one to predict the results of experiments. That is one reason why self-experimentation is not popular among granting agencies.
