I considered scale and uniformity of bias as possible differences before posting, but I'm not sure I believe it's qualitatively different. Maybe it's analogous to someone who puts all of their faith in a friend or family member and believes anything they say? Is this more than that - a folie a deux by proxy? We have folks who already do this: they are religious fanatics and listeners of Joe Rogan. Is it really that different?
