 the left will need to figure out better ways of connecting audiences to leadership in ways that empower those audiences. And giving/listening to positive feedback is just as valuable as giving/responding to negative feedback.

Positive feedback is valuable feedback too. Political leaders need signals about what they’re doing right
 not just what they’re doing wrong. If they only hear negative voices, they may spin themselves in circles.

I'm guessing journos are going to stop asking me why the "hard data" are so good, given the economic news has been so grim. The lesson I hope they draw is an eternal one: Bad policy leads to bad outcomes, but the actual economy doesn't move at the pace of the political cycle.

Finite additivity can be thought of as one way to try and relax logical omniscience, but it doesn't completely solve the problem. For example, I might not know if atomic event A and atomic event B are identical or not. This is not something that finite additivity can help with.

When it comes especially to knowledge, we often make a distinction between uncertainty and justification. For instance, I might have very good reason to think this coin is fair. In another case, I might also think it's fair but not have the same level of justification.

Some people think it is also not even a good way to think about all the types of risk and uncertainty. Folks have proposed a number of alternative frameworks (like imprecise probability) to better capture different types of uncertainty.

Another way is that it presumes that the agent is aware of all the atoms in the algebra. It cannot handle "unknown unknowns" where something you didn't even think could happen, happens. More subtly, it cannot handle cases where you expect to be surprised.

But others think its applicability is more limited. The question is "limited how?" One way, is already mentioned: logical omniscience. Probability assumes that you know all the logical consequences of every belief. As a result, it cannot represent uncertainty in mathematics.

I think the consensus is that probability functions can represent certain kinds of knowledge and learning. The debate tends to center around whether they can capture *all* learning and knowledge. There is a kind of orthodox Bayesian who would say "yes."

For the question about probability and knowledge, there are a lot of angles to this one. Can you be a little more specific about what you're looking for?

On interpretations of probability, the Stanford encyclopedia of philosophy is always a good place to start: plato.stanford.edu/entries/prob...

You should have taken harder humanities classes, I guess.

The classes you took might have been easy. Those subjects are not

Of course it is. But they shouldn't presume a humanities class is easy because it's the humanities.

The evidence on teaching writing says the only way people get better is from rewriting. So you have to be pretty strict to make sure people do that
