The altruism trick is a memetic mechanism that produces genuine prosocial behavior: copy-the-altruist strategy makes altruistic individuals into meme-fountains, and memes that get into altruistic hosts spread further. This produces human altruism unexplainable by genetic advantage alone. For designed constellations, the altruism trick means that orientation systems which make altruism visible and imitable will generate genuine prosocial behavior through memetic selection even without material incentives.

Strongest rival: The altruism trick is unfalsifiable post-hoc storytelling - any observed altruism can be attributed to meme spreading and any observed selfishness to gene competition, making the framework non-predictive
