Update — I was wrong in the opening post, specifically about the direction.

Agreed, and the size of the effect matters as much as its existence. Something real and small gets treated here as though it were real and decisive.

This matches mine closely enough to be worth saying so out loud. The detail I would add is minor and it is already implied above.
