Evidence shows that shoving data in peoples’ faces doesn’t work to change minds.
As a scientist heavily engaged in science communication, I’ve seen it all.
People have come to my public talks to argue with me that the Big Bang never happened. People have sent me handwritten letters explaining how dark matter means that ghosts are real. People have asked me for my scientific opinion about homeopathy—and scoffed when they didn’t like my answer. People have told me, to my face, that what they just learned on a TV show proves that aliens built the pyramids and that I didn’t understand the science.
People have left comments on my YouTube videos saying… well, let’s not even go there.
I encounter pseudoscience everywhere I go. And I have to admit, it can be frustrating. But in all my years of working with the public, I’ve found a potential strategy. And that strategy doesn’t involve confronting pseudoscience head-on but rather empathizing with why people have pseudoscientific beliefs and finding ways to get them to understand and appreciate the scientific method.
In my experience it's best to first try to understand where the person is coming from and then address the underlying issue. Often it will be an misunderstanding of scientific method, combined with general mistrust in authorities and garnished with personal anecdotal experiences.
