Thanks for making this post. I especially like the paragraph:

There is similarly no easy way to use the “try it and see” method to sort out what ethics and meta-ethics to endorse, or what long-term human outcomes are likely, how you can have a positive impact on the distant poor, or which retirement investments really will be for the next forty years. For these goals we are forced to use reasoning, as failure-prone as human reasoning is. If the issue is tricky enough, we’re forced to additionally develop our skill at reasoning -- to develop “epistemic rationality”.
