In a food-ish vein:
Once, in high school biology, we did an experiment. We were each given a questionnaire and a set of little paper strips coated in a variety of (non-toxic) chemicals. We were asked to taste the strips, one by one, and mark down whether they tasted sweet or salty or bitter or sour, etc.
The answers varied from person to person; the same strip might taste bitter to one person and salty to another. And the results weren't fuzzy. We had decisive and different perceptions of the taste of each one. We learned that the way the taste buds perceive certain substances is genetically determined. We simply don't all taste things exactly the same way.
At the end of the experiment, we tallied up our questionnaire, and the results placed us in one of several "taste groups." (There was probably some technical term, but I don't remember it.) Some taste groups were more common, other less - I was a member of an obscure fringe taste-sect. And the questionnaire explained that members of a given taste group tend to have certain types of preferred foods. As I read the preferred foods for my group - pickles, sauerkraut, pretty much anything with vinegar and salt - I began to salivate, and my stomach rumbled with hunger. They spoke the truth.
So what's today's moral? Science is cool. Stay in school. Never ever question the scientific method, or we will crush you like so many ancient civilizations before you, while chanting "Screw you and the anti-empirical horse you rode in on. Screw you and the anti-empirical horse you rode in on. Screw you and the anti-empirical horse you rode in on..."
Did anyone else do this? Does anyone know what I'm talking about.
