Analysis of information sources in references of the Wikipedia article "Marc Gafni" in English language version.
In my opinion Mr. Gafni answered the relevant questions truthfully. This opinion is tempered by the fact that I had no access to the original complaints.
...this was a poor issue for the polygraph. The polygraph is believed to be most accurate when a person denies committing a specific physical act...It would be more appropriate to examine Sarah as to whether she had written a letter, than him as to whether he had read it. More importantly, testing on the contents of a letter received nearly 30 years ago is inappropriate because memory is easily modified over time – often significantly – based on additional knowledge and experience....Mr. Gafni was adamant that he had a very clear memory of that letter. We agreed that if he wished to be tested on this issue, I would have to include a caveat to the effect that because of the complexity of the issue, one could not have as much confidence in the results as one would have if the issue was unambiguous. That notwithstanding, Mr. Gafni asked to be examined on this additional issue....We discussed his recollection of the letter from Sarah Kabakow. He said his memory of that letter is very vivid to this day. He received it after he had broken off his relationship with her. It was a sweet, tender letter in which she said she loved him, she knew he loved her, they were meant to go through life together, and only thus could they be happy....Conclusion It is my professional opinion that Mr. Gafni answered the relevant questions truthfully. Because of the nearly three decades that have elapsed since Ms. Kabakow's letter would have been received, confidence in this conclusion is necessarily somewhat less than would otherwise be the case.
