“Science Is Real.” If you’ve driven or walked through an affluent liberal neighborhood in the last couple of years, you’ve likely seen this simple, three-word declaration on one of those “In This House, We Believe:” signs, alongside “Black Lives Matter” and “No Human Is Illegal.” They, it is implied—those mouth-breathing conservatives—don’t believe in science.

For a long time, I was in this camp. It baffled me that conservatives could be so cut off from reality. Why couldn’t they understand that the earth is billions of years old, that there are mountains of evidence supporting the theory of evolution, that climate change is real and human-caused? Why did they cling so tightly to their ignorance?
