How Certain Are You That PSI Effects Are Real?

I think there are more people in the middle part (25-75%) than I'd have expected. Currently 40% of respondents.

I think that's a positive state of affairs. If the question had been posed with regard to a list of specific types of psi phenomena, my own votes would vary wildly across that list. It implies, among all of us, a healthy dose of scepticism, not in the sense of being dismissive or close-minded, but in the sense of asking questions, gathering evidence and being open-minded, rather than committed to a belief for or against.
