Using here as an example, rod bearing failures etc.. people hear of 1 report of it happening and spread the word. 1 instance of failure quickly becomes 20,30,40 people talking about it on here, or Facebook or the real world in garages etc. All of a sudden a fairly minuscule percentage of failures is being discussed as a common fault. Likewise, genuine false information being reported - someone asks for a Torque setting for something and a reply is given that isn’t correct by the book - it’s what they’ve torqued theirs to or what they think will be ok. No one else either knows enough to correct it or bothers. Other users then search for that torque setting, find said thread and as it hasn’t been corrected the take it as gospel and even reproduce the information when someone else asks and once again the misinformation spreads like a virus. The same can be said for opinions and subjective topics.. a user asks what the effects of introducing part X into their setup and gets another users opinion which may not be the same on their setup or to their tastes / opinion. But the original reply is taken as this is what will happen if doing this mod. Internet forums and user groups etc on Facebook are a fantastic resource available for free in most instances but I think we just need to be aware that it’s almost like quoting Wikipedia and it can be dangerous to take the information available as fact. This has always been the case and predates the term fake news so is this where it’s spread from?
