How did you arrive at the conclusion that I was fixating on IQ? What did I write that gave you that Idea? IQ is an important factor in decision-making. I didn't say it was the ONLY factor.
Certainly, we are talking about my perception of your comments, so in the value and importance I perceive you place on a high IQ based on your comments, and the extremely high IQ you used in your thought experiment all contribute to my perception. In addition, I have tried to emphasize that having a high IQ does not mean that one would necessarily act in anything other than their own self-interest. As an example, one can be highly intelligent and be a sociopath or psychopath. In fact, I seem to recall that they tend, in general, to have above average intelligence. As a response, you seemed only to emphasize those with higher IQ make better decisions, in your opinion.
In decision-making for a group or a whole society, I would put more emphasis on emotional intelligence paired with a quality college or graduate school level of intelligence which would be a broader swath than those in the top 0.01% range. Having one who can empathize and value others and inherent differences would seem a higher priority metric concerning decisions for society as a whole.
The electorate is half the problem. The other half is that the political parties are often offering voters a choice between Dumb and Dumberer.
Our system is better than the authoritarian regimes of other nations. That's about all we can say for it.
Perhaps it is a certain personality type that is attracted to, and seeks political office, and, for whatever reason, that personality type has some inherent flaws. Really, it requires a great talent in selling one's self, but you can't choose what it is you want to be or what you are selling, you must conform to some idealized conception held by a sufficient number of the electorate that you can be successfully elected. In the American system, the potential candidate is essentially left with two idealized conceptions on the opposite ends of a spectrum from which to choose.
I think maintaining a system with strong checks and balances is our first defense against things getting too out of control. As for potential improvements, I would like to try universal term limits for all offices. I would also like to have a system of run-off elections if no candidate breaks 50% of the vote, or maybe some form of ranked elections. My objective in these changes would be to give a stronger voice to the moderate middle of the electorate and disenfranchise the entrenched two-party system we have now.
Somebody with expertise in Political Science may have reasons why my changes might not achieve my desired result, or my desired result is not desirable, etc., for I am not an expert.
It would be my presumption that electing representatives that better reflect the desires of a broad middle of the electorate would result in greater fairness in public policy, coming back to your issue of fairness.
