QUESTION TEXT: Researcher: The role of chemicals called pheromones…
QUESTION TYPE: Necessary Assumption
CONCLUSION: Pheromones no longer affect humans’ sexual behavior.
REASONING: Pheromones clearly control animal sexual behavior at an automatic, chemical level. But free will allows humans to take sexual decisions at a psychological level.
ANALYSIS: This is quite a bad argument. There’s no proof that pheromones can’t influence psychological decisions.
___________
- This is far too broad to be necessary. Planetary motion doesn’t have a chemical explanation, so therefore it must have a psychological explanation, according to this assumption.
- CORRECT. If voluntary action is influenced by chemicals, then pheromones could influence the actions we take according to our free will.
- The researcher never said that only humans are unaffected by pheromones. There may be other animals with free will.
- The researcher never said why our actions are voluntary. Our free will is only important because it may make us immune to pheromones.
- The researcher said psychology controls our sexuality. They never connected psychology with pheromones, and they never tried to explain why we still have pheromones.
