"The unstated premise is that rule by elites may be preferable to rule by the people if science should someday discover that average people will be irredeemably swayed by their prejudices and will not make their political decisions based on their intellects."
I disagreed. In my opinion, the argument of the paper suggests nothing of the kind. While your idea is interesting, I believe it delves too far between the lines and looks for some deeper meaning. The Boston Globe is not challenging our form of government. They're merely commenting on the research that suggests people are hard headed, generally speaking.
While your paragraphs about the US Constitution and system of Checks and Balances are spot on, they have nothing to do with the article in question.
This is simply my humble opinion.
