Don't take my comment to mean the question is off topic. It's at the very least a borderline question. What I meant was that the research you remember seeing was probably something a biologist or a psychologist would have a better shot of identifying than a philosopher. Earlier today, I spent considerable time searching for a concept that turned out to be the product of psychology and not philosophy. It has applications in philosophy, but the only reason I knew about it was from my reading on economics of all things. I might have asked the question here, but there's not much chance for getting the answer I was looking for if only because the people who read this site may never have read about the research I was groping for.
Is it a bad question or off-topic? Well, if there's a place to ask psychological/biological questions on StackExchange it would be better to ask there. Once you've found the research in question, you could ask a philosophical question about the research here.
It doesn't earn an upvote from me, because it isn't well researched. That might not seem fair, but that's one of my criteria for an upvote. It doesn't hurt (the rest of us) for the question to sit with no votes until the end of time or until someone who knows the answer sees it. Disappointing to you, I suppose, but we all must live with disappointment from time to time. ;-)
