If you do possess the ability to change people’s goals, you should start there. Convince people that Effective Altruism is worth doing for its own sake. If you can manage that, you don’t need the dark arts in the first place. If you need the dark arts, then you can’t do what you’d need to be able to do to make the results favorable, and shouldn’t use them.
I’ll repeat:
