Your definition of Entropic is: a process of degeneration marked variously by increasing degrees of uncertainty, disorder, fragmentation, chaos, etc.; specif., such a process regarded as the inevitable, terminal stage in the life of a social system or structure.
What you’re trying to do is measure how one person’s influence has a negative effect on a dynamic situation or task? If you want to take ONLY IQ’s in to account, then you get two groups of people with equivalent IQ’s but in one group throw in a person who has a mental disability of some sort, where they’re IQ is much lower. But I don’t think you are going to get the result you want.
You’re working with personality types, not just IQ’s. I’ve known PA-LENTY of very highly rated people IQ-wise, but they were more disruptive and would miss the point of exercises completely and waste time and piss people off to the point people left projects before they were done.
Wait…. are you GAMING? Is this for an RPG?
