I'm sorry, I didn't do a good job of explaining what I meant.

And I do very much appreciate that this is a fraught subject and it is hard to talk about with respect, and I appreciate your very civilized tone throughout.

Here's my main point, in I hope a clearer way.

Since 1900, medical science has increased our life expectancy by thirty years — I am enjoying those thirty years right now.

Aeronautics allow us to fly everywhere on the planet in hours, and rocketry have taken humans to the Moon, and our probes out of the solar system. The total amount of computational power available to all humans has increased by a factor of quadrillions - we can realistically synthesize not just sounds but human beings in motion.

And against that background, we have a small number of experiments in parapsychology where some accumulated probabilistic result is a bit different from what is expected.

These results, even if true, are not anywhere near the magnitude to completely revolutionize everyone's worldview, which is what the existence of ESP would require.

I've been reading the ESP literature for well over forty years and it's been one disappointment after another.

There is no other field in science which after 130 years still has no operating theory, mechanism, or ability to demonstrate it to a room full of school children.

The only result with any predictive ability in the field still seems to be Susan Blackmore's original monumental meta-analysis which showed an inverse correlation between magnitude of results and tightness of controls — and if that is true, then there is no there, there. Yes, I know this is old news, but there is still no great discovery.

The reason there aren't aeronautics deniers is that you can get on a plane and fly to Timbuktu. Few people doubted the atomic theory of matter after the atom bomb was detonated.

Where's the ESP device, or system to make ESP even a tiny bit more accessible, or any sort of directly visible result that you can in some way reliably show in a classroom setting to regular people?

Where's the Theory of ESP? What corresponds to Newton's Laws, or Maxwell's Equations, or even a principle like Natural Selection?

After significant time and money put in by the US and Russian and Chinese military, and separately by academia like these studies you cite, and by private investors and researchers, and after more than a century, why isn’t there anything except these tiny statistical anomalies?
