I'm not talking about fiction, I'm talking about interviews with detectives on a show like 20/20.
The way they talk about both people refusing to take the polygraph and whether they pass or fail belies a belif in their credibility. I also know some police personally who speak in the same way but that's a much smaller sample size.
This is still subjective feels.
I absolutely believe that some police detectives have real genuine faith in polygraphs being accurate. I strongly suspect a good many do not.
That's orthoganal to how detectives that don't have faith in polygraph results being "real" feel about people that refuse to take them.
Many may feel that people that refuse tests that supposedly tell truth telling from lying can be ranked with people that refuse a search or to unlock their phones ... ie. that's a sign that that they very probably have something to hide.

These are professionals being interviewed who are projecting all manner of things, if they don't actually trust that polygraphs work as scientifically accurate tests that reliably detect lies they are still motivated to not say so and to project belief, that's all part of the theatre of manipulating suspects.
