Finished the chapters in my learning course regarding Motivation for Learning and Intelligence and Learning. I'm happy about what I learned about the first lectures, it a very handy set of tips for GM and Parents; particularly about letting go and when rewards actually reduce value of a game.
Regarding the second part, I'm glad to know that many, although not enough in my opinion, are of the same opinion of what IQ measures. In fact the lecture gave some really handy tips in measuring IQ from historical sampling, allowing me to make a generic set of assumption of how Learning contributes to the Point Total to number Of Intelligence stats. As how oversimplification ruins and mis-communicates a whole lot, I'll just do that wrong and say: IQ = Intellectual Achievement.
Intelligence is a stat in the open system I'm working on. But I've been careful to define it in a way that it can accommodate the current view and normalization of what counts intellectual achievement in a given era. I cannot go about bringing down IQ scores in older eras; but I can make its definition change relative to our current era and our scientific understanding and standards of knowledge and education of the context era.
More importantly is what I've figured to be the role of Wisdom, the counterpart of Intelligence and its role in an RPG. Wisdom is basically an unconventional kind of intelligence, it is defined as what ever intelligence may be but we are not able to define and measure as easily. What happens is that high wisdom allow us to achieve things high Intelligence can but with different methods and often through indirect means; what happens is that Wisdom is the catch all term for Smarts we have trouble defining.
Basically you check for Int or Wis, which ever is higher. In puzzles we can use Int or Wis as the "controling" attribute. In fact in modern settings, Wis and Int is very interchangable in going about a puzzle or situation in Real world situation; but in tests where a certain attribute is being looked into most of the time you can only look at Int.
Intelligence and wisdom, given how little we currently know in the science (despite how it appears to be a lot) as to be defined. Which is all Ok, because part of the open system tool set is to to package and quickly communicate assumptions. Of course the default will be my own justification and definition; but as an open system has other people put their assumptions then it becomes possible that we can find more and more assumptions that cater best to us.
