Is there a spectrum of different kinds of theories? The theory that I have hands feels very different from the theory that supermassive black holes exist in the center of every galaxy. Does your account make a distinction between these two cases?
I feel like most things I learned about Popper are probably wrong. I was taught that Popper thought you could only falsify theories you could never get evidence for them? Is that correct? Or is that another misreading?

No, he believes that (although there are parts of Replies to My Critics that say something about decisions that 'sound like smuggling in induction'). But it's an aberration from the rest of his work. He advances a theory of corroboration (one that's false, cf. Miller, Tichý '74)

So (what you could call) 'logical negativists' or hypothetico-deductivists that don't accept theories of confirmation need to provide a different, non-evidential account of rational theory-preference. I think they succeed on their own terms, but others disagree.
