I’ve thought about this a bit, and I don’t think I fully understand the point you’re making.
Surely, absent more context, a 10k donation is a strong signal? It only becomes weaker if you assume the donor is very rich (e.g. “it’s <5% of their income”). But in the effective altruism community, that assumption would often be wrong.
Being vegan is a less noisy signal of personal commitment than giving 10k to charity, so people will take this more seriously, whether that’s fair or not.
I don’t know whether this is correct on average, but it likely depends a lot on context. For example, being vegan in Hollywood might be seen as trend-following or health-related, while being vegan at a university might come across as principled and self-sacrificing.
Also, I don’t think it’s true that most of the people you’re trying to signal to don’t have important information about you. If you’re telling friends you donated 10k, they likely know whether that’s a major sacrifice for you. And if a news story says “doctor donates 10% of her salary”, most readers will grasp the significance.
I’m not sure it’s true that people generally see a 10k donation as less of a personal sacrifice than going vegan. But even if they did, I doubt the effect is especially important?
