99.999999%
A completely unscientific, pulled-out-of-the ass statistic that people use that is not based on ANY actual statistical research, when they want to assure you that their very bullheaded, highly-opinionated conclusion is true ALMOST all of the time, but oh-so-humbly admit that there is an infinitesimal, but non-zero, chance of a case happening where they might be wrong. Sometimes people keep it simple and just say 99%, but feel free to add more nines after the decimal the more smug and self-assured you want to sound. A way of having it both ways, and saying "I believe that I am right all the time!" without TECHNICALLY saying that you think you're right ALL the time.
