Aeschines, though I tend towards the occam’s razor end of the argument, I have no ‘script’ myself; I am genuinely interested in the subject, but I’ve never seen any “beyond doubt” laboratory proof of psi. Have you got something you could show me that indicates this?

Here is good place to start, which indicates where the debate lies today.
In short, these experiments involve people guessing an image in highly controlled conditions. Chance would be a 25% hit rate, whereas results are very consistently 35% or higher.
The skeptics who argue against such results with adequate information and sincerity (i.e., have gone quite far beyond the level of shouting, “There’s no evidence whatsoever!”) tend to do one of three things:
-
Criticize the experimental conditions. At first, decades ago, they had plenty to criticize, but their input has been encouraged and put into practice. Now even skeptics admit that the experimental conditions are rock solid. Insincere critics sometimes take the approach of finding a tiny flaw or two and using that to invalidate the entire result, but essentially this approach is a no go.
-
Hand wave the results. Recognize that something is going on but act as though it doesn’t matter or will be explained satisfactorily later, etc.
-
Argue the statistics. If Experiment A is successful, for example, they argue that it was merely chance that made it so and, given enough similar experiments, there will be a reversion to the mean and no effect discovered. This leads to, as I said above, very recondite and contentious arguments about statistics.
My view, based upon a fairly decent understanding of science and statistics, is that the effect has been proven and it’s one that jibes with our everyday experience. In my view, people deny psi when they feel that its existence doesn’t fit their worldview.
