Yup, you’re totally right, it may be too easy to commit in other ways, outside this protocol. But I still think it may be possible to create such a “main mechanism” for making commitments where it’s just very easy/cheap/credible to commit, compared to other mechanisms. But that would require a crazy amount of cooperation.
The vast majority that I know of use ad-hoc and agent-specific commitment mechanisms
If you have some particular mechanisms in mind could you list some? I’d like to compile a list of the most relevant commitment mechanisms to try to analyze them.
I’m not sure I’d call it “too easy to commit in other ways”, so much as “this doesn’t describe a commitment”. The power of a commitment is that the other player KNOWS that no strategy or discussion can change the decision. That’s the whole point. If it’s revocable or changeable, it’s not a commitment, it’s a meaningless statement of intent.
Real-world commitments come in many forms, from public announcements to get social pressure for follow-through to legal contracts with third parties to simply not bringing money so being unable to pay for something.
Oh yeah, I meant the final locked-in commitment, not initial tentative one. And my point is that when committing outside is sufficiently more costly, then it’s not worth doing it, even if that would let you commit faster.
