Finding a good experimental protocol that would be able to show statistical significance, even if the impact is very low, normally requires large samples. If PSI does exist, then it would be understandable that the subjects would be affected by fatigue which would also reduce significance.
Another factor that comes to mind is self confidence. If it exists, until PSI is proven, most subjects would face self-doubt which would negatively impact their results.
Writing that actually gave me an idea though. That hypothesis could potentially be easier to prove than simply trying to prove PSI itself.
We would need to look for a trend between self-perceived confidence level and results. This way, if there is a real impact, then it would be statistically noticeable more easily with a correlation test.
As you'll all notice, I put a lot of "ifs" in my sentence, to hopefully avoid dismissive answers and possibly get more constructive feedback on the experimental approach.
