I think they are saying that people have a tendency to react to their impressions about what is going on, which may not resemble what is actually going on. Being reactive, they are prone to over-reacting. This seems trivially true in the way people of every political stripe work themselves up into a froth over misconceptions about how government works, how the monetary system works, etc.

It's a fair observation, but I personally don't think we should take a wait-and-see approach to the breathtaking corruption and everything else going on.

"Trump's plan is not project 2025, but is Agenda 47 which is on his website" is an objectively true statement.

If a reporter were to write a report saying "I think that Trump is likely to implement Project 2025, because half of his staff worked on the project, and he regularly goes to meetings with the people who work on it" This would be an inference.

But the inference is probably more true than the objectively true statement.
