I have always been suspicious of the "herd mentality" - especially when that herd self-proclaims themselves to be the smartest ones in the room. My healthy distrust is in good company:
"Beware committees, conferences and leagues of intellectuals. Distrust public statements from their serried ranks. Discount their verdicts on political leaders and important events."
~ Historian Paul Johnson
I believe this to be especially true with the study of history.
