It's not even about "results" in the economic sense so much as it is about the 85 guy mentally being a child compared to the 145 guy. Seriously, how do you as an adult regard a typical 10-year-old? You certainly see him as a human being, and may even love him if he's your child, but you're certainly not gonna ask his advice on anything important or trust his judgement on much of anything... you're gonna sit him in the corner while the adults figure it out.
Agreed. And it is not like you can hope to radically change the person with an 85 IQ, since the IQ is partially genetic in nature and relates to the physical characteristics of the brain.
Unfortunately, the 85IQ thing becomes even more visible when you have a whole society with people with IQ's in the 80s/low 90s. In a modern society with people of all types, the structures of society is solid enough too enable "the 85 guy" to live a good life where he can do work that is suitable for him. Unfortunately, when you have an entire society of people with low intelligence, the drawbacks becomes more visible. Very high crime, poor organization of society, poor average education and a very poor economy (unless they have natural resources floating around or some "trademark" product in high demand). And this is not meant as a pwning, its just reality. The whole culture and functioning of the society = built around the functioning and thinking processes of a person with the IQ's in the 80s, thus, it will resemble a society with the mentality of very young people, and it's not very suprising that most "85IQ" societies functions like the social dynamic of kids
You can compare the last example to a group of 1 million people, all with every genetic marker for "high risk of Altzeimers". The group can live a healthy lifestyle and all, but they will simply have a tremendous amount of Altzeimers compared to a group of 1 million people where nobody has any of the genetic markers for Altzeimers.
