A Canadian law & ethic professor and Canada Research Chair in Health Law and Policy describes OT and the other Cove Trumpettes:
"Of course, personal identities will also influence the kind of information we seek out. Often, people will find someone who appears to be “like them” (that is, aligns with their personal identity) to be more credible than an expert. This is one reason why a blogger or YouTube pontificator can hold more sway than an academic researcher who has spent an entire career studying the relevant issue. If the YouTuber speaks to and confirms a pre-existing worldview that is core to who you are, that message has a good chance of winning out over science-informed information from an expert.
When a belief becomes linked to personal identity, it can become very resistant to change. Indeed, once a person feels part of a community or a movement, the adherence to a science-free position may begin to feel not fringe-y, but “brave and righteous” — as a recent study of the Australian anti-vaccine movement found."
