Higher IQ people probably tend to be more trusting — high IQ environments tend to be more honest and cooperative.Stepping away from the presidential election for a moment, allow me to do what the tagline advertises and validate Steve's stereotype.
The GSS routinely asks respondents whether they feel as though most people are trustworthy or not. The following table shows the percentages of people, grouped by intelligence*, who say that "generally speaking, most people can be trusted". For contemporary relevance, to avoid linguistic problems, and to avoid racial confounding, responses are from 2000 onward and restricted to non-Hispanic whites who were born in the US (n = 2,458):
People of modest intelligence are correspondingly more likely to assume that someone or something is intentionally taking advantage of them when the evidence is unclear or ambiguous.
Stepping back to the election, this presumably goes some way in explaining Trump's working-class appeal and the allergic reaction many upper-middle class cuckservatives have to him. Foolishly trusting people and institutions unworthy of trust is one of cuckservatism's defining characteristics.
It's also why the FBI investigation redux, in concert with Project Veritas' videos and the steady stream of WikiLeaks' revelations is potentially lethal to the harridan from hell. It's pushing the most inherently trusting, Midwestern-nice Flanderesses to the breaking point. Each of these Clinton scandals that keep piling one on top of another are, individually, much worse than the Watergate scandal that brought down the Nixon administration was. It's getting more and more difficult, even in the lard-filled crevices of Erick Erickson's corpulent mind, to imagine how Trump could be worse than Hillary.
As the West becomes less European, it becomes less trusting. The instinctively high levels of trust intelligent people have is a feature in a society where people and institutions tend to be trustworthy. Such societies are becoming increasingly rare, however, and it will in large part be up to the Joe-bag-of-donuts to save clever sillies from themselves before current demographic trends become irreversible and the Occident gets swallowed up by the tides of darkness forever.
GSS variables used: TRUST(1-2), YEAR(2000-2014), RACECEN1(1), BORN(1), WORDSUM(0-3)(4-5)(6)(7-8)(9-10)
* Respondents are broken up into five categories that roughly forms a normal distribution; Really Smarts (wordsum score of 9-10, comprising 13% of the population), Pretty Smarts (7-8, 26%), Normals (6, 22%), Pretty Dumbs (4-5, 27%), and Real Dumbs (0-3, 12%).
