Here's the deal: unless required by your job or by parole, never volunteer for a police polygraph. Many law enforcement polygraphers are dishonest, and intimidate targets with the test, emotionally manipulating them into confessions. Sometimes even false confessions. If a defense attorney offers one, take it. Your results should only be revealed if the result is "no deception detected." Otherwise, the results are not revealed. If you are not being honest, you can try countermeasures, but don't count on them to work. Cops WANT you to believe you can fool the test. Then they tell you you failed, and pressure you for a confession!

Polygraph is inadmissible in court cases thanks to a Supreme Court ruling in the early 1900s by people who fully understood it was bullshit.
That hasn't stopped certain government agencies and businesses who firmly believe their workers need to be subjugated to abuse through it (read: it can cost your job if you fail). AKA the double down on stupidity move.

TL;DR: control your heart rate and breathing. Create a nervous response to calibration questions and calm yourself for as much as you can when you need to lie.
Source: have fooled a polygraph. It was a shirty one but still made it look like truths were lies and vice versa at will.

Did the examiner change their shirts often during the test?

No but they also weren't properly trained to use it (just a crash course). Is this a reference to the article because I didn't actually read it, just assumed what it would say.
