No actually there’s a large body of quashed research over these decades that went against the prevailing hypothesis. It’s one of the key examples of how peer review fails to consider novel approaches in the face of consensus even if consensus is shown to likely be wrong. The fact the original research driving the consensus was fraudulent at worst made it that much more sad.

To be clear this isn’t about whether it’s right or wrong it’s about that science involves investigating all avenues with evidence, proof, and rigor. Group think is how we end up incorporating bias into science, which is anti scientific.
