Said literature gives advice, reasoning and conclusions that is epistemically, instrumentally and normatively bad.

I remember hearing about studies where economics and game theory students ended up less "moral" by many usual measures after completing their courses. Less inclined to co-operate, more likely to lie and cheat, more concerned about money, more likely to excuse overtly selfish behaviour and so on. And then these fine, new, upstanding citizens, went on to become the next generation of bankers, traders, stock-brokers, and advisers to politicians and industry. The rest as they say is history.
