Study cаse. Scientist оr philоsоpher? Alysson is а reseаrcher who studies people's exercise habits. She has read numerous studies on human motivation, including philosophical ones, and has tentatively concluded that individuals are more likely to exercise when they engage in meaningful physical activities. To test her tentative conclusion, Alysson spends fifty hours a week observing and interviewing students at the Intramural Building. After collecting data for three weeks, Alysson establishes the following causal explanation: "People who find physical exercise meaningful always enjoy the experience of exercising at the gym and are more likely to return." This is the best explanation that matches Alysson's research.
