I'm not at all sure "science" has better mechanisms than hobbyists.
Not sure "science" has much of a referent at all really.  "Established
academic experts" have mechanisms, ok, but not clear they are better.
Rather, I'd just emphasize the "established" descriptor.  If most people who
are widely acknowledged to be very expert on closely related topics reject a
position, well then all else equal that position is probably wrong.

But then comes the hard part: how can you ever justify disagreeing with
most established experts on a topic?  Like cryonics for example.  Of course
established experts make mistakes, but how can you ever know you've found one?
