If there is anything I have taken away from homebrewers in general when presented with any type of scientific evidence they scream for blind tasting to prove anything/everything. Even when presented with said things, if it goes against their bias, they discount it.
The moral of the story is accept there is an issue or don't, try new methods or don't. But the science is the science and that doesn't change regardless of bias, stubbornness, comprehension, etc. It is what it is.
