Even so, prohibitions sometimes contain truths: the Jewish one against pork could prevent parasites. What if forbidding psi is similarly well intended? Opening awareness can be gnarly (the yoga and seeker paths in India know this), and it might happen that "when you see them, they see you" adding to difficulties. Even so, many things are difficult at first. But worthwhile things take effort.
That said tho: it's not as if religions are the paragons of virtuous behavior they may wish to be seen as, so it may not do to simply accept prohibitions on faith alone. And remember prohibitions evolve with time, even religious ones. Also, you cannot discount the possibility that not wanting to democratize access to the divine, or even spiritual, is simply about centralizing power and control.
Your point on advances in other collection is well taken tho! But some factual errors require correction: you don't need to be 'receptive to psi' to have it work, just try (unless faith precludes you to, and I don't suggest violating what you believe); also it's not 'subjective' in the sense you want - it's people looking at data, and they're interpreting it. That's the subjectivity, and that's like every analysis ever.
It helps to consider it just another sensor, or sense organ, or skill. It's not supposed to be sole source. It's not pretending to be infallible. Can you sink 100 3 pointers in a row? Not even the best NBA can all the time, every human skill is dynamic and on a bell curve. Regarding philosophical prohibitions, consider like access to data to help you make better choices.
How about an analogy? You are a person looking at a wall. Along the wall walks a caterpillar. It goes from left to right. Standing where you are, you can see its objective. Some tasty leaf sprouting from a gap a few feet away. The caterpillar senses it, but does not see as clearly as you - if for no other reason than your 3D perspective - from on the wall, it can really only grasp a small way in front. What the caterpillar doesn't see is a large vertical crack, impossibly to pass, that breaks its path just ahead. You tho, do see that crack. Because of your perspective. You see the little guy heading towards it, whereas if he just took 30 degrees to the right he'd be able to go around it. From where he is tho, he can't see it. So without the knowledge of another perspective, without other data, the little guy is gonna waste more time. And might even run into trouble in the big crack!
That's like psi. Dive in! Unless your beliefs about risk preclude that - in which case I'd say, be more careful, because those prior beliefs could cause you to have ideas which would get in the way and might be challenging for mental health.
Anywho, thanks for your fun reply! :)
To clarify, for a Christian the issue wouldn't be that doing A is forbid or that the belief of it being wrong would be challenging for mental health. The issue would be simple that doing A is wrong.
For real world everyday problems normally it is an application of already solved theory or it isn't worth working on at all. We still need researchers to look at and expand our theory which in turn allows us to solve more problems in the real world. And there are real world problems that we pour enormous amounts of effort into solving despite lacking theory, but these areas move much slower than the much more common application of already solved theory and so are vastly vastly more expensive. (this is how we get smaller chip architectures, but it is a planet scale problem to solve)
