Here's a closer look: to accept psi, you would have to reject evolutionary biology.

It would be such a humungous advantage to communicate telepathically, see the future or remote locations, or manipulate the physical world by thinking, that there's no way evolution wouldn't have optimised the f* out of it by now.

We don't wonder whether birds have wings, or whether dogs have a sense of smell. That we can wonder whether we might have psychic powers means we DON'T, to a very high probability indeed.
