Also, to comment on this:

An article about assessing the soundness of the academic mainstream would benefit from also discussing the ways in which the message from, and even the research done in, academia is corrupted and distorted by commercial interests. Economics is a case in point, but it is a big issue also in drug research and other aspects of medicine.

That would fall under the "venal" part of considering the ideological/venal factors involved. I agree that I should have cited the example of drug research; the main reason I didn't do so is that I'm not confident that my impressions about this area are accurate enough.

One fascinating question about the problem of venal influences, about which I might write more in the future, is when and under what exact conditions researchers are likely to fall under them and get away with it, considering that the present system is overall very good at discovering and punishing crude and obvious corruption and fraud. As I wrote in another comment, sometimes such influences are masked by scams such as setting up phony front organizations for funding, but even that tends to be discovered eventually and tarnish the reputations of the researchers involved. What seems to be the worst problem is when the beneficiaries of biased research enjoy such status in the eyes of the public and such legal and customary position in society that they don't even need to hide anything when establishing a perverse symbiosis that results in biased research.
