the entire scientific system has long been undermined by for-profit orgs funding research that is hard to replicate and/or paying off enough scientists to make their research qualify as peer reviewed.
and just look at the outsized impact healthcare administration has on front-line care. these are political organizations run by non-practicing, ladder-climbing doctors in name only that force dogmatic decrees and have been censuring practicing doctors that spoke out against vaccine mandates.
and science is regularly corrupted simply by peer pressure to conform - such was the case of lysenkoism, which set soviet science back, and we have increasingly more lysenkoism in the west where shit like this happens -
