You're presuming by vested I was referring only to money... I wasn't at all.
No, I got that.
Being accused of biased is like being accused of breathing air-- it's ubiquitous and inescapable.
Which is why is said, "No one from GBF, Brulosophy, me or anyone is free from bias.
That is the limitation of experiments with people."
Rather than providing actual relevant evidence, they've deferred to 70+ year old papers (appeal to antiquity)
I'm aware of that logical fallacy. If you call research published in peer-reviewed journals in the 1990's and 2000's an appeal to antiquity or authority then I don't understand logic (which I admit is a possibility).
I'm a skeptical person and questioned the LODO guys often. One of my main concerns was the lack of available research. After some Googling it's apparent this is a legit concern- it's just harder to find the information because we aren't members of the BA, MBAA or brewing science students. The only question left for me is whether it is worth the effort as a homebrewer who rarely has a keg last longer than 2-3 weeks.
