After I give lectures-on almost any subject-I am often asked, "Do you believe in UFOs?" I'm always struck by how the question is phrased, the suggestion that this is a matter of belief and not evidence. I'm almost never asked, "How good is the evidence that UFOs are alien spaceships?"
Holland is a fairly small country, and in a weird way, somewhat conservative. That might surprise people because it is a very tolerant place, but it's also a somewhat Calvinist country. There isn't much flexibility in changing people's perspectives.
