Well, you know the deal about "extraordinary claims require extraordinary evidence".

People have tried to test vaguely related things with varying degrees of effort for a long time, and whenever it's been done carefully, it's either nothing, or not-obviously-nothing-but-really-really-tiny, with a possible exception of the Stanford Psi experiments, and even that didn't manage to meet the bar for James Randi's challenge. (Yes, I know remote viewing isn't past lives. But they're both hypotheses about the existence of and access to some sort of mental realm that isn't obvious.)

Particularly with hypnosis, the space of possible answers is not well understood, and can plausibly vary based on things like time of year of birth and birth year (both of which have somewhat predictable effects, presumably mediated by the different cadence of formative experiences--you can find all kinds of funny things like that in big databases...and check for reversal of the effect w.r.t. the calendar in the Southern Hemisphere!), not to mention the primary impact of hypnosis being to induce a state of high suggestibility which makes implantation of "memory" an exceedingly large risk.

So you've taken on a fiendishly difficult research project, with from your descriptions not nearly a concomitant degree of care.

I think the main problem is that you have to up your game, not that people aren't willing to lower their standards. Finding funding for research in such an implausible area may indeed be difficult, but given the never-ending supply of, say, celebrities who are highly credulous of dubious claims (e.g. Paltrow), while it is indeed a lot harder than getting an R01 funded, it's well in the "possibly achievable" realm, not "the orthodoxy is inexorably suppressing my revolution" realm.
