Consensus does not imply evidence. It does imply the existence of heuristics- people can at least agree on what types of methods may be used to arrive at an answer to the question. Having bad heuristics may mean you get wrong answers, but no question can be answered without heuristics.Feil wrote:Be careful when assuming that consensus implies evidence, however.
Being able to find consensus answers that are broadly shared among a significant chunk of a large group is a necessary, but not a sufficient, condition. If you can find such an answer it might still be wrong. But if you can't find such an answer, then the odds are any answer you try to come up with will be just as wrong.
The significant chunk of the group doesn't have to be a majority, or even a plurality, either. It just has to exist, in quantity and quality that suggests that you haven't just roped together a crowd of maniacs or fools.
