"such as the fact that their paper is published in a philosophy journal, and the guy having a history degree instead of a physics degree."

"-- argument from authority, very unscientific. If an unemployed poodle shaver publishes a replicable experiment, it is science."

Not only is it an unscientific argument, it's just wrong. The guy did his undergraduate and masters in physics, then switched to history of science for his doctorate because he realized that nobody was going to fund what he wanted to work on and he needed a job. He also works with other physicists who do have doctorates in physics.
