|Achieving consensus - Wikipedia|
If we are to make intellectual progress, this is if we are to move from untrue ideas towards true ideas, then many of our current ideas must be wrong. In a few hundred years at most, we shall presumably have better ideas than many of those we now hold dear. In other words, the wisdom of crowds is only temporary.
I think that’s why consensus is so untrustworthy, especially scientific consensus. When a new idea comes along, the old one is consigned to the dustbin of history and we should not be so naive as to think it won’t happen to us. It will.
If progress continues, then the majority must eventually be proved wrong in a number of important assumptions. There is no wisdom to be found in crowds, only the temporary and illusory security of consensus. A humbling thought one might say - if it wasn't so bloody frustrating.
