A relative (yes, for real) is accused of a sexually related indiscretion with a family member many tens of years ago. It basically boils down to a bit of ass grabbing and naughty words. Not that that was right. 

However, the alleged incident has been blow WAAAAY out of proportion by the accusing party as a way to manipulate the family. 

My relative, uniformed about poly other than a basic belief that polygraphy "works" voluntarily paid for and took an exam, answered all questions (he composed them!) honestly and got "inconclusives" and a  "weak" deceptive indication.  He was totally freaked out about it before going, but wanted to do something the defend himself - yet even MORE freaked out that in an attempt to defend himself, ended up incriminated. And, unfortunately, members of the family are waiting for results...

He took the test a second time after reading the TTBTL and failed in a worse fashion. His polygrapher deduces his anxiety over his life being destroyed weighs heavily on the physical responses...i.e., any direct reference to a vindictive accusor trips him up.
His polygrapher now recommends writing things down on paper and referring to the accusor in third party terms as a way to mollify triggering responses by mention of the accusors name.

Please, anyone, advise in general or advise as to whether or not he should go through this a THIRD time. 

Thank you,
