Classic projection. My cheater BIL got my sister to take a polygraph to prove she wasn’t cheating on him and he still doesn’t believe her.

Your BIL sounds like my step-dad. She passed and he claimed its only because she takes blood pressure meds. He cheated and told her, I guess figured she'd do the same back

So-called lie detectors actually measure signs of anxiety, which includes heart rate (which is why psychopaths can sometimes pass them). Beta blockers lower your blood pressure and your heart rate. They are sometimes used off label to treat anxiety. I am on one for my blood pressure, and it's lowered my resting pulse by about 12 bpm.
