An earlier post said there were

I don’t distrust responsible scholars but those aren’t the ones who usually get boosted on the History Channel, and anyway, most of the people who promote novelties are journalists, not scholars. A journalist who wants to sell his articles will skip over 9 examples of cautious, genuine scholarly evidence, none of which will get him published, and focus on one scholar, often taking him out of context, to “prove” that A)Jesus was married to Mary Magdalen, who was a bishop; B)the Air Force is hiding alien corpses and crashed space ships; C) doctor’s new diet plan means you can eat like a pig and get skinny. D)etc.
Chesterton was a journalist, and he knew how wildly the media and
some scholars could build a mountain of conjecture on an ounce of evidence. My academic experience suggests to me that
any kind of name exposure, getting quoted assists an academic career.
Chesterton was heavily endorsed by skeptics such as Martin Gardner, who disagreed with his religious views, but honored his common sense and insights. Chesterton’s skepticism is sorely lacking in today’s media driven society.
