Once upon a time people had a fairly simple test for the power of a God. They simply wanted to know, did he help you to win battles? Constantine supposedly adopted Christianity before a major battle and then won it, cementing his conversion and prompting him to make Christianity the official religion of the Roman Empire. When Romans proved themselves stronger with their god, other communities took this as proof that this was the god to worship. A few centuries later, a similar wave of "proof" in the form of power and conquest swept down the silk routes from northern Africa to China with Islam.
It is easy to mock this test but it's not the worst test of efficacy; does adopting your god make us more powerful, more able to get what we want? For whatever limits we have in making arguments or accepting data that contradicts deeply held beliefs, we might still benefit from this simple test: does that worldview make people prosperous or poor? Does it give you the power to live a life of your choosing?
Right now facts seem to have gone out of style. Republicans and their president have largely dismissed the importance of facts, particularly the ones that challenge their worldview. People worry that the party - the country even - will never recover and will be hijacked by irrational worldviews that weaken the country. It might.
I think, though, that this worldview is too ineffectual to last long.
In San Francisco, average household income in 2015 was $119,406. In West Virginia average income was less than half that, $56,425. Less than half of San Francisco's population is white; 94% of West Virginians are white.
Making the assumption that every baby has the same potential at conception - regardless of race or gender - San Francisco is obviously doing a better job of creating prosperity for its residents. It might be that their residents are genetically superior to West Virginians who suffer from a lack of racial diversity; or it might be that the worldview of San Franciscans is more effective than that of West Virginians.
There are a variety of ways to define the difference in worldview but one simple one is to look at how these two communities voted. Fewer than 10% of San Franciscans voted for Trump; more than two-thirds of West Virginians did.
One of two things will happen in our country. Either the Trumpian worldview will spread like a virus and the country will become like West Virginia, a place where Trump holds rallies when he wants comfort. Or people in places like West Virginia will see the worldview of the people in San Francisco - a worldview that embraces diversity and disruption, a place that funds startups rather than tries to protect a coal industry that first emerged in 1740 - as more powerful and adopt it. If the first happens, the country will look back at the 20th century as a golden time; if the second happens, West Virginians will look back fondly at the time that their grandparents adopted a new worldview that made them prosperous and powerful rather than poor and angry, roaring approval of a man who manages to connect with facts only about 25% of the time.
