What do you mean by this? the field of psychology is perfectly capable of policing itself, and it's rejected much of the conclusions of its historical predecessors.
> In order for the same to be true for the hard sciences we would need to be failing to replicate experiments which hinge on germ theory, atomic theory, the standard model, etc.
"hard sciences" also fail to produce results relevant to most people. Sure, they can maybe make better batteries, but how can they explain how dysfunctional society is?
EDIT: We can also directly blame the poor communicational skills of "hard sciences" for diet culture. "hard sciences" have failed in their efforts to produce a population that can reason about nutrition in an evidence-backed manner, and this can be traced directly to how scientists choose to present their data.
