I am uncomfortable with the blindfold record. I believe it can be done, and I am willing to believe that he did it, but I need proof that he could not "nose peek". I remember years ago Martin Gardner, debunker and amateur magician, observing in his book, Science, Good Bad and Bogus, that with most blindfolds one can see down the length of the nose.
Search on YouTube for his name to see the record competitions. Someone report back please. Seminumerical 02:39, 23 August 2006 (UTC)[reply]
I, and many other people at Canada/USA Mathcamp (a few of whom have Wikipedia accounts with enough contribution to be considered "trustworthy", many of whom don't), have seen him solve the cube blindfolded. Except he's not actually blindfolded: he puts the cube behind his back (and closes his eyes). Now yes, I suppose it's theoretically possible he could have someone give him information through blinks or something, but he's done it in open areas with few people and with many people and while I can be skeptical of magic and sleight of hand, it seems just as reasonable, if not more reasonable, that he can do this without cheating as someone who can play chess "blindfolded" (which I've seen people do by sitting in another room without being able to see the board). If you want more testimonials (i.e. "consensus" or "proof"), leave me a message on my talk page. Telso 08:12, 14 October 2006 (UTC)[reply]
Please read WP:RS, which explains what a reliable source is for purpose of verification. Note that it does not include getting testimonials from people (which cannot be considered in any way as "proof" or "consensus" on Wikipedia). All information such as his records (whether blindfolded or not) needs to be supported by reliable sourcing. Unfortunately, much of the MathCamp related info on Wikipedia does not appear to be so. --C S (Talk) 08:32, 14 October 2006 (UTC)[reply]
Use the source that's in the article. The World Cube Association has verified him solving a cube blindfolded three times. Or are you saying that you don't believe the WCA's verification methods, and that all their blindfolded competitors are "looking down the nose"? As telso points out (however anecdotally), you don't need an actual blindfold to solve a cube blind. rspeer / ɹəədsɹ 18:42, 14 October 2006 (UTC)[reply]
That looks good to me. I didn't follow the link far enough apparently. There is no need to be extra skeptical as Seminumerical is, as the WCA records are more than sufficent as a reliable source. --C S (Talk) 21:21, 14 October 2006 (UTC)[reply]
Interestingly, a few years later there was a competitor who did indeed peek down his nose. He got caught when someone stuck a piece of paper between his nose and his cube. Ever since such a piece of paper is mandatory. Judith Sunrise (talk) 11:35, 24 February 2018 (UTC)[reply]
