So if you suspect a problem with epistemology, you can't conduct an experiment, because to do so is "bad faith"?
Do you display bad faith in the theory of gravity by conducting an experiment? Is the whole scientific process a bad faith attempt to determine objective truth by underhanded manipulation of the universe?
You can't conduct an experiment to establish why gravity happens. This experiment is like someone dropping a tennis ball and a bowling ball from the tower of pisa and then writing a conclusion that gravity has a liberal bias against bowling balls because it slows them down to the same speed as a tennis ball.
