Broscience is the predominant brand of reasoning in bodybuilding circles where the anecdotal reports of jacked dudes are considered more credible than scientific research.
A sarcastic term implying that the time tested, muscle building wealth of knowledge developed and utilized by successful, experienced bodybuilders is inferior to the continually shifting hypotheses of articulate, textbook-savvy 155lb. chemists with little or no real world first-person experience to substantiate their conclusions. The term "Broscience" is oft repeated on bodybuilding and fitness oriented internet forums in an attempt to demonstrate online dominance as a substitution for success in the arena of actual bodybuilding.
There is even a site called Broscience.com which highlights how science conflicts with popular myth in the bodybuilding world.
I think there is some similar stuff in the paleo world.....Palebro science perhaps. People like Kurt Harris and Matt Lalonde are key in fighting the myths with science.
