The people standing in the park trying to tease out which horse is fastest from previous observations have the advantage over anyone just going with their feelings.

No, the metaphor breaks down at that point because there is no peeking over the wall, there is no listening to talk from inside the stables. We're not even at the track.

It is a thing nobody has any good reason to act like they know anything about in a scientific capacity.
