"In a particularly uncomfortable section, Hancock quotes Marc Defant’s Skeptic magazine review of Hancock’s Magicians of the Gods and lists each and every error he found in the piece, which is scheduled to run next month in Skeptic, two years after the book was published."
The first thing to know about Defant in this discussion, is that he posted a 'draft' article that was left on Shermer's website for nearly six months, from January 2017 until the time of the interview in May of 2017. According to what Graham had do say, starting around 2:08 in the interview, Defant claims that he only posted it there for the benefit of his students.
On that point, here's what Colavito had to say:
" Defant said he did not realize that the public would read his draft article, which he intended to share with his students. (Seriously?)."
Colavito almost certainly says "seriously" because he, like myself,presumes this to be a bald-faced lie, as Shermer's website is well-visited, and Defant had to know that his 'draft' piece - which Shermber never bothered to read - would be seen by many beyond his classroom. This is text book pseudo skepticism again: throw whatever is available out there. Use adhesive, the longer the inaccuracies stay out there the better, because part of the agenda is to smear the other.
It only got worse. when he wasn't talking over everybody - which Rogan called him out on - Defant was saying stupid irrelevant things like, Graham didn't know anythng about gravity. Hancock explained that this red herring was about his (Hancock's) referencing a writer who had exotic things to say about gravity AND that this was NOT the reason why he had referenced the writer in the first place. Hancock quoted his own words, which clearly demonstrated that he (Hancock) was not interested in the remarks on gravity, and from that it became abundantly clear that Defant had either not read what Hancock had to say carefully, or that he was making things up in... order to slander Hancock.
Around the same time Defant said that Hancock said that a possible future capacity had something to do with precission, which is utter bullshit. I understand Graham's argument well on this point, and basically he was suggesting goes as follows. A possible future comet strike may have been anticipated by the ancients, and they may have used a future position of the Sun as a means of saying when this was supposed to occur - in John Major Jenkins' Galactic Alignment Zone, as per his thesis on the Long Count calender possibly being designed to target the location of the Sun, relative to the Milky way, in circa 2012.
To state that Graham was saying that precession somehow might cause the comet strike, or whatever exactly the pending possible catastrophe might be, is pure ignorance. Then Defant, an academic, told that world that precession cycles last 21000 years. Any quick internet search will show that the period is around 2600 years. Why comment on something that he plainly doesn't know anything about? Because this is another pseudo skeptic. Marc Defant might as well have said that in the sport of American football, five points are awarded when a team scores a touchdown. What he said, was that astonishingly stupid.
Defant also called Hancock a con artist at the end of the article, which is totally in keeping with everything else I have mentioned. "By the end of the book, the only ‘message’ I am left with is that Hancock has a real knack for conning a hellacious number people into buying his books.” Clearly, his writing was an attempt to smear.
Since it had been posted on Michael Shermer's website, I firmly believe that Defant's 'draft' article would still be there today, in its form at the time of the Rogan interview. But since it was exposed as being inaccurate, live on the Internet, Shermer had no choice but to tell the world he was going to have it pulled and revised.
And so we come full circle: the pseudo skeptic will always rant on about 'alternative' subjects never being peer reviewed. What do we have, Shermer never bothered to look at the article once in the nearly six months that Defant had posted it on his site, or if Shermer did, he was content to let the garbage stay as it was, at the expense of Hancock.
