Not sure what "broscience" you're referencing, but there structure of the show was very transparent -Drew was an actual doctor, board certified addiction treatment specialist and got his start volunteering in hospitals during the aids crisis. That's when he was told about loveline and he wanted the opotunity to spread awareness.

Adam was unapologetically an unqualified comic relief. But of course, his role was to represent the unqualified "everyman" with Drew there to moderate and correct back to empirical fact and best practice. But he also listened and learned over the years. With time he did better saying the actual right thing a lot of the time through shear repetition. But that was part of the problem.

Eventually, like the problem with smartphones in general, he started to think that simply because he HAD certain knowledge, that he had actually EARNED it. He got more popular than Drew, I think that ultimately crushed Drew's spirit because, along with a lot of good, he was a BIG narcissist. Realized he couldn't get the respect or pay that Adam did after 20 years of schooling, sacrifice and he just checked out and became a turbo grifter.

Adam gradually removed anyone from his life that would criticize or remind him that he wasn't an expert (literally documented day by day in his radio show and podcasts) and he finally became a monster on an entirely different level. Genuinely think with him the change was so abrupt because of CTE. He played a lot of football in the valley in the 70s/80s where nobody carted about safety, and then he boxed in the same era. He just must have had so many head injuries. I hope they study his broken brain when he dies so there can be a little relief in framing his 180.
