Randi's work was a major influence in me becoming a skeptic. Back when I was in my late teens, I was interested in the supernatural, UFOs and things like telekinesis and related woo. I encountered a website affiliated with Randi (don't remember exact details), when I was looking to find what would convince those skeptical of the things I believed in.
To my surprise, I found that the evidence they wanted, with the clear standards, wasn't an unreasonable ask at all. And so I started to look for evidence that would qualify. I suffered (still suffer, but rarely) of the phenomena of awareness during sleep paralysis (ASP), and my researches revealed that the ASP state could be, with practice, used as a launching off point for OBE (Out of body experience).
AHA! There was the proof - so I first looked for OBE research, that would offer clear proof that a "soul" had left a body. Things like placing an item high up in a place where someone would have to climb up to see what it was to know what it was... or float up there while "out of body" to see what it was.
I found one account but "mysteriously" the subject who was able to pass that test had disappeared, and it could not be repeated. Furthermore I found the test woefully badly supervised.
Disappointed that I could not find any good evidence of anything leaving the body in an OBE, I engaged in a period of practicing to induce the experience in myself, which started with increasing my chances of experiencing awareness during sleep paralysis.
After weeks of trying, I succeeded, and managed to induce an OBE from the ASP state. Immediately after I was kicking myself because I hadn't prepared a test. I did prepare a test after that, having a friend place some item without me knowing what it was, in the back of a high shelf in my room.
After more trying, I managed to repeat my OBE, and floated up to look what was on the high shelf - I saw a low vase.
After the experience, I climbed up to see what was there; it was a pair of scissors. I was quite disappointed, but didn't try to make excuses, but concluded that even if it felt very real, the OBE was probably a hallucinatory experience, or a lucid dream.
A few experiments further confirmed that for me. That was a beginning of me questioning my previous beliefs critically, and soon becoming a philosophical naturalist, and a skeptic.
So Randi was one of the major sparks for me in making me who I am today.
I am grateful for his contribution, and his passion in spreading rationality. I'm just one of many people he influenced, around the world. His was truly a life well lived!
