Ever since the pioneering work of Mary Douglas on risk back in 1992, anthropologists have understood that there is a difference between what is actually dangerous and what people think is dangerous. Scientists can measure the probability of you being struck by a bolt of lightning or getting hit by a car. But our fears are not based on extensive scientific study, nor are they the results of our own idiosyncratic psychology. They are shaped by the culture we live in and the history we’ve collectively experienced. The sad thing, anthropologically, about Donald Trump’s executive order on immigration is that it does not make Americans safer, just makes some Americans feel safer. The tragic thing about the order is that forces others to suffer for the sake of our own false sense of security.
