I think this kind of 
start-with-the-desired-conclusion-and-work-backwards thinking 
seems to be alarmingly prevalent in the computing world (and on 
the Supreme Court). It is certainly a requirement for being a 
Rust fan-boy.

But I can tell you that I saw this kind of thing 50+ years ago 
(human nature just doesn't change), when performance measurement 
was my specialty. I constantly ran into people who "just knew" 
why certain code, even their code, performed as it did. 
Measurements (evidence) were/was unnecessary. I could tell you 
many war stories where these people were dead wrong (almost 
always), even about the behavior of their own code.
