I don't see groupthink affecting Bitcoiners as much as people in other spaces.

Everything seems to be an argument; SBR, Saylor & MSTR, Ordinals, mining centralisation v decentralisation, ossification, ect.

Even when it comes to politics outside of the protocol itself, people are arguing on here all the time.

Some haven't even figured out Batman is better than Superman...

Groupthink, to me, is what people do when they all agree on something they do not understand or haven't thought through deeply.

Personally, I don't see that nearly as much with Bitcoiners, as I do with any one else.
