A postscript to "what happened to me"

[Bucky Ball]

How exactly can you tell the difference between individual opinions that happen to agree and "group-think" ?
Oh you can't
Never mind.

One clue is to find out how well an individual can justify his claims with evidence, arguments, etc. 

If a person says he doesn't need reasons to hold something to be true, it may well be a sign that he's opted for group-think. Or if he expects his assertions to be accepted with no challenge.

And how would one find that out ? 
Do you think people who accuse an entire forum of group-think have actually asked every member of the (supposed) group how they arrived at their opinions ? 
The reply might work for one person, but the general accusation that group-think exists at all, remains unanswered, and un-supported, unless every member of the (supposed) group is asked. Those who accuse others of "group-think" really have no way of supporting their accusations, and in fact it's quite insulting to tell a group they did not individually arrive at their positions on various subjects, but took their opinions from a group, (most of whom they don't even know), and the member of the group not even identified.
