Of course, you are not qualified to say how those with paranormal powers would feel either. What I can say for certain is that the fact that nobody has claimed the prize says very little about the existence of paranormal powers. Aside from those with paranormal powers who value their anonymity, there are also those with dangerous powers, those who can make more than one million dollars through their powers, those who fear experimentation, etc. Even if I did have paranormal powers, I would deny it on a public message board.
Regardless, my opinion of the changes has nothing to do with psychoanalyzing paranormal people. The reason I don’t think the changes make the test too selective is because the lures of the test are still prize money and fame. Anyone who has paranormal powers and wants to use them to get prize money and fame will find a way to gain the required notoriety to take the test. If they do not want to give up their anonymity for prize money and fame, then they would never have taken the test in the first place. Thus the changes exclude nobody with actual paranormal powers.
