To create new understandings, one has to hold several conflicting theories, and a variety of facts, hints and speculations in ones mind at once, playing with them like lego bricks, looking for ways they might fit together, having fun, unafraid of the silly, the unknown, the crazy.
a good chunk of the good stuff, and 100 times as much garbage, lies outside the respected halls of accepted scienceThat's true. Everything that is currently now in the "respected halls of accepted science" has its origins in some theory that was once on the outside.
But as you said, there's 100 times as much garbage as good stuff on the outside. I would say 100,000 times, not 100 times.
To me, one of the tests if an outsider's piece is "good stuff" or "garbage" is how many links s/he can build between the outsider theory and the accepted stuff. On those grounds, the article posted here fails my own personal smell test. Though I admit, I myself am no scientist.
