Probably became commonplace somewhere post-WWII, as quackery started to finally disappear but other bullshit had to replace it, where pharmaceuticals were becoming the Big Money and nepotism began to take serious hold.
Any soft science, especially ones that require speculation and biases, can probably be thrown in the trash easily.
Believing science that works with the actual, rigorous method depends on how much you're willing to deny observational reality. Some throw quantum physics in the trash, others throw cosmology in the trash. Even then the sci-method path can require decades to get just a "theory" down, and even then it doesn't go beyond "theory", sort of an extension of the Incompleteness Theorems applied to this field.
I wonder how many times this has already happened in a variety of differnet Sciences TM. Can't let reality escape into the public now tsk tsk.
