A "WASP ethical framework" is barely a thing, if at all. The Princeton founders were motivated by moral obligations derived from a particular subset of Protestant Christianity. They were dissenters from the Anglican establishment, so it feels weird to try to bunch them in under the "WASP" umbrella. I have no idea if people who wrote the honor code were Calvinists too, but that was the seed ideology. It's not something that generic "WASP culture" gets to claim absent from the foundational theology. I'd wager that most WASPs at Princeton today do not share genuine belief in those foundations, if they don't cheat it's only because of social pressure, which tends not to hold up as well under pressure.
