I am the ultimate rationalist! My willingness to sacrifice for someone follows a perfect distribution along kinship genetic similarity:
Siblings: share 50% of their genes, so I’d be willing to take a 50% chance of dying if it meant their genes could potentially live on and reproduce
First cousins: share 12.5% of their genes, so I’d be willing to take a 12.5% chance of dying
So what about for a random friend? If they could just take a quick DNA test, then our genetic relatedness would determine my willingness to sacrifice for them.
Supposing that I die while saving them, I would want a guarantee that they propagate their genes in proportion to our genetic similarity:
Siblings: I would want them to have at least 2 kids
First cousins: I would want them to have at least 8 kids
Random friend with 1% genetic similarity: That’s right! 100 kids please! 😉
