To be honest, as I chat with more and more random strangers these days it does begin to dawn on me that we all do roughly spend ~70 years on this planet devoting our attention to one thing or another, and that though people might not have what is seen as "classical intelligence" (i.e. high IQ's, political savvy, high empathy / sociopathy, etc.), we are genuinely absolute genius's in one particular field or another.
For example, I had an old roommate whose politics would make me drink and stare at the horizon whilst he consistently acted against his own self interests to punish people he was told are responsibly for his financial lot in life. But, he was an absolute wizard when it came to predicting the outcome of a sports game. It could be anything - football, hockey, tennis, whatever - he immediately ran their stats straight off the top off his head, summarized their strengths and weaknesses and came out with an outcome that was on the whole close to the truth.
Another example, my ex. We never really had deep philosophical discussions about the state of the world, and her consumerist lifestyle was one I tried to actively ignore. But, she was incredible at turning a house into a home -- her interior design skills would genuinely surprise me at how well-thought out and in-depth they were, not only in terms of style and decor, but also in the way that she would execute and coordinate the tasks with me to beautify our home.
TL;DR -- I do really think most people have high intelligence in one specific field or another, we just value people unequally using classical measures of success (wealth, education)
80% prediction rate isn't anything to bank on :P
