I think Jim Carrey has a point. He was vaccinated, and he is obviously suffering some kind of brain damage.
Nope. Normal human working brain. It isn't that Carrey is stupid, or damaged. It is that his brain is stuck in a rut. We are, *all* of us, subject to the kinds of cognitive biases that lead to positions like his. If we rifled through all the things each of us thinks is correct, we'd find something that isn't really justified, but we won't budge on. It just so happens that Carrey's is something that matters, and intersects with public health and current events. And he happens to be famous, so we hear about it.
If you are famous, or powerful, you need ought to have solid backing of your arguments before you open your mouth. "I believe," "it is known," and, "Conspiracy!" are not good enough.
