Still looking for a clear reason why Randi changed tack.
If the reason was clear, you would have been able to mention it in one short phrase, not avoid it.
This one point, about Randi "changing tack" on his offer, is very clearly disingenuous, and demonstrates that rather than doing any looking, you are believing what you are being told by others who want to hold on to similar beliefs. That's a terrible way to accumulate "knowledge."
First, On January 4, 2008, it was announced that the prize would be discontinued on March 6, 2010 in order to free the money for other uses. In the meantime, claimants were welcome to vie for it. Do you notice anything here? TWO YEARS and more notice, giving anybody who really thought they had something ample opportunity. If Randi was trying to escape for fear of losing money, that's the absolute worst way to do it.
Even then, in 2009, the foundation changed its mind and said the offer would NOT expire in 2010, but continue. This, I think, shows not very much fear at all, wouldn't you agree?
On March 8, 2011, the JREF announced that qualifications were being altered to open the challenge to
more applicants. Whereas applicants were previously required to submit press clippings and a letter from an academic institution to qualify, the new rules now require applicants to present either press clippings, a letter from an academic institution, or a public video demonstrating their ability. The JREF explained that these new rules would give people without media or academic documentation a way to be considered for testing, and would allow the JREF to use online video and social media to reach a wider audience. Does Randi look scared witless to you yet, in opening the prize up even further.
Now remember, the challenge was first created by Randi in 1964, so by 2011 it's been going for 45 years! During that time, about a thousand people have applied, but no one has been successful.
In January 2015, James Randi announced that he was officially retiring and stepping down from his position with the JREF. In September 2015, JREF announced that their board had decided that it would convert the foundation into a grant-making foundation, and they will no longer accept applications directly from people claiming to have a paranormal power. In 2015 the James Randi paranormal challenge was officially terminated.
Once again, can you see anything interesting? That termination happened FIFTY-ONE (51) YEARS after it was offered. Does it still look sudden and surprising to you?
Sorry, but your ESP friends are not being honest, and you're not looking further than what you hear and want to hear.
