It is not. It's a contrarian newspaper, gives some interesting folks a platform, but mostly cranks.
(I really don’t know, but it does seem that this info at least is coming from multiple places?)
It's a funny old magazine though, they really do get all sorts in there and print stuff that others wouldn't. It's entirely editorial though with huge biases.
I'm glad it exists and read it often, but I'd go checking everything I read in it if I was after some facts.
