I loved your reference to "consensus delusion". People using "there is a consensus" when arguing about anything angers me. So what? If a smart guy in a room full of fools and the smart guy knows something the fools do not, their consensus is not going to invalidate truth.

Yet consensus is used often. It is used in many areas and I've noticed that people often give in and agree with the term consensus as long as it is a consensus on something they agree with.

I am NOT illustrating these points to pick a side, I am using them to point out where the term "consensus" is often used to justify or shut up the opposition.

• Anthropogenic Global Warming (aka Climate Change)
• Vaccines

There are other reasons that can be used to argue for your position with either of those areas. The term "Consensus" is irrelevant though.
