A lie detector test cannot prove you guilty, but it can sure help
prove you innocent.
All a lie detector tells is how nervous you are. Most of the time,
under the circumstances, that is same thing. But there are a high number
of false positives.

Refusing to take one just ups the ante.

Has absolutely no impact on the trial since, at least in the US, you
can't introduce refusal to take a lie detector at trial. Makes the cops
marginally more interested, but most of the more seasoned detectives
know that refusal means nothing in real life. They still like to raise
their eyebrows and pretend otherwise, but that is mostly to elicit other
guilt responses in the person.
BTW: At least when I was more active in the area in the 80s, most of
the polygraph operators said they would only take voice stress analysis
tests if it was them or their families. They thought it measured
truthfulness better.
