| Mar 28, 2021 at 6:30 | comment | added | Gerry Myerson | There are no false proofs, by well-ordering. Assume there is a false proof of ststement $S$. By well-ordering, there is a shortest false proof $P$ of $S$. Remove one symbol from $P$, thus generating a shorter false proof of $S$. This contradicts the minimality of $P$, and we are done. | |

| Apr 22, 2012 at 22:27 | comment | added | Suvrit | Indeed, a false proof is not the same as a false belief, and at no point did I imply that! But I mentioned Gowers' question, because the top answer's "false proof" (Cayley-Hamilton) also occurred there as one of the answers. (Believing a "false proof" to be true, is a "false belief", and because of that, there is a strong chance of intersection between the two questions) :-) | |

| Apr 22, 2012 at 15:36 | comment | added | Steven Landsburg | A false proof is not the same as a false belief. One can read a false proof, know for certain that the conclusion is false (so there is no false belief), and still have trouble pinpointing the error. | |

| Apr 22, 2012 at 5:46 | comment | added | Suvrit | the answers to this will turn out to replicate many of the responses to Gowers' famous question on "false beliefs", so I am not so sure if this question should remain open. | |
