At the begining of the "When Radical Ideas...
" panel around 5:00 min in the video, Mr. David Talbot states the idea is to perform the 'acid test' of convincing "a good person who has no advanced prejudices in one direction or another" of EU ideas. And these selected good persons are people, he states at ~5:22: ""I have real respect for Michael Shermer and Gary Schwartz".
Obviously, from Mr. Shermer's words on the panel and his article in Scientific American he wasn't at all convinced.
The test — "Who have you convinced?" — blatantly failed.
But apparently it wasn't EU ideas being tested — for the consequence of the failed test was not any change in such ideas, not even a dispassionate rebuttal of the "dismissive review", but an acid, generalized attack, a total lack of respect for Michael Shermer, transmuted into a very BAD person.
