I think these people are just as prone to behavioral biases as the rest of us. This is not a problem per se, it's just that it is difficult to interpret what is happening right now and what will happen, which creates an overreliance on the opinions of the few people closely involved. I'm sure given the pace of change and the perception that this is history-changing is impacting peoples' judgment. The unusual focus on their opinions can't be helping either. Ideally people are factoring this into their claims and predictions, but it doesn't seem like that's the case all the time.
