@Ben Jones:

I don't disagree about the utility of the term, I'm just trying to figure out what should be considered a dimension in "thingspace" and what shouldn't. Obviously our brain's hormonal environment is a rather important and immediate aspect of the environment, so we tend to lend undue importance to those things which change it.

To continue to play Devil's Advocate, where does the line get drawn?

If you extend the hypothetical experiment out to a sufficiently sized random sampling of other people, and find that Wigginettes are more likely than default to induce biochemical "attractive" responses in people (despite not occurring with any greater frequency), I assume that that would then then justify the term. Even though it's still not a word about Wigginettes themselves, but about other people's reactions to them? Describing things in the real world doesn't seem as simple as entity.property.

I understand the point here, that using words to create meaningless divisions is either mistaken or malicious. I was just trying to see how an example played out.
