The whole point of science is to acquire knowledge that eventually gets communicated outside of the scientific body producing it. If the papers never leave the ivory tower, or never lead to other papers that do, it's just navel gazing.
When a scientific community has a chunk of their work that everyone in the tower knows is bullshit but never gets corrected, that metadata doesn't leave the ivory tower. What happens instead is that papers like this flutter out the window, get picked up by journalists who don't have access to tribal knowlege, and then get spread wide and far. The information appears legitimate because it did come from a trusted scientific body. It just had the necessary context that it's actually bullshit left off.
Every scientific community has an obligation to ensure that the papers they publish and advocate actually mean what they say they mean. If nothing else, because not doing that ultimately tarnishes the brand and undermines the trustworthiness of that community.
