Some concrete exemples might help your case. Science wants to be humble. The people we hold as examples of very careful, meticulous scientists (like Cochrane) have very weak beliefs and a lot of quantified doubt about everything. Science shouldn't be trusted blindly, because it's an incremental process not an Oracle of Truth. But random people with opinions, in my experience, are even more likely to have strong beliefs and overconfidence in them.
