A lot of what I do here on this blog is write posts intended for my intellectual opponents to try to sway them to my side. Of course, the human mind is very good at convincing itself to ignore information that challenges deeply-rooted beliefs
With that in mind, Darmouth College assistant professor of government Brendan Nyhan writes:
I recently conducted a study with several colleagues in which we found that parents with mixed or negative feelings toward vaccines actually became less likely to say they would vaccinate a future child after receiving information debunking the myth that vaccines cause autism.
Keep in mind that this is not all parents - only those who already had been tainted with anti-vax nonsense, but it's still a troubling revelation.
