Sorry, not my intention to strawman. It is alien to me.
Doesn't the strict rationalist have trouble with the truth value of statements conditioned on false statements?
No. Not bayesians, at any rate.
You are looking for a philosophy which tells you what the indicated course of action is. That means that trivialism is poorly suited for you.
What's an "indicated" course of action? How is it different from "what you should do", below?
You are looking for a philosophy because you want your philosophy to tell you what you should do. That means that trivialism is the perfect philosophy for you to practice.
What does trivialism predict? What does it tell us to do? Does trivialism let me predict anything more accurately than any other theory? A single instance of one thing that it would predict more accurately and/or reliably in reality than any other theory would make it instantly much less worthy of derision.
At present, it is to me nothing more than a humorous thought experiment similar to "This sentence is false."
When you try to make predictions, use a philosophy that performs predictions well. Bayesian rationality provides many useful tools to determine what the expected results are, but no tools to determine which expected result to choose. Trivialism provides tools more well suited for deciding in the absence of information.
Straight from Wikipedia.
I just had to stare at this a while. We can have papers published about this, we really ought to be able to get papers published about Friendly AI subproblems.
My favorite part is at the very end.
Trivialism is the theory that every proposition is true. A consequence of trivialism is that all statements, including all contradictions of the form "p and not p" (that something both 'is' and 'isn't' at the same time), are true.[1]
