Suppose I was an unusual moral, unusually insightful used car saleswoman. I have studied the dishonest sales techniques my colleagues use, and because I am unusually wise, worked out the general principles behind them. I think it is plausible that this analysis is new, though I guess it could already exist in an obscure journal.

Is it moral of me to publish this research, or should I practice the virtue of silence?

• It might help people resist such techniques.
• It might help salesmen employ these immoral techniques better.
• Salesmen are more likely to already understand much of the content - vulnerable outsiders would have more to learn
• Salesmen are more incentivized to learn from my analysis.
• It is quite interesting to read as a purely abstract matter.
• I like producing and sharing interesting research.

Obviously the dishonest car salesman is just an example so don't get too tied up on the efficiency of the second hand car market.
