I tried this for a few days recently. By day three or four I went to bed at around 6am and woke up at 2pm. Didn’t feel great the rest of the day. Went back to a more regular sleep schedule after that and feeling better now.

You can structure discussions any way you like as long as you make sure the structure won’t break criticism chains.

Comments are for commentary or criticism, not elaborations on the same idea. The same idea shouldn’t be spread over multiple posts. That breaks criticism chains.

Veritula threads don’t work like Twitter/X threads, where people post elaborations on the same idea in comments. They used to have to do that because Twitter enforced a character limit. Now they still do it by tradition. And I’m guessing it’s an adjustment coming to Veritula.

If you realize you need to add more info to an existing idea, put it in a revision, not a comment. Again, #5250 seems like a revision of #5249. The revision of #5249 would then be a combination of both.

#5278​·​Dennis Hackethal, about 5 hours ago

Possibly yeah. It doesn’t look like you were going off that. #5246 isn’t a proposed solution. Neither is #5250. That’s an elaboration on #5249.

Would it be better to make them all root ideas?

#5274​·​Benjamin DaviesOP, 2 days ago

But the UI won’t reflect that automatically. Now you have to remember which threads have this structure and which don’t. Will you remember that, say, six months from now?

This approach breaks search functions, where the system only goes off the ‘Criticized’ flag. Now the system shows some ideas as rationally adoptable even though they aren’t.

#5270​·​Dennis Hackethal, 3 days ago​·​Criticism

There’s no need to single out corroboration or verisimilitude as special kinds of criticism.

Preference formation using either can easily be reduced to the method of counting pending criticisms:

Idea A fails to survive two tests.
Idea B fails to survive only one of the two.
Idea C says: I have only A and B; I don’t have time to create another; although both are false, I have to act; so for now I prefer B since at least it passes a test A doesn’t.

If idea C has no pending criticisms, then we should adopt it. (And thus ‘transitively’ adopt B.)

#5265​·​Dennis Hackethal, 4 days ago​·​Criticism

We can rationally prefer A over B if A has no pending criticisms whereas B has at least one.

The property you mention is the existence of pending criticisms.

#5264​·​Dennis Hackethal revised 4 days ago​·​Original #5258

You can still prefer A over B if neither has pending criticisms. The “if and only if” is too strict.

#5263​·​Dennis Hackethal, 4 days ago​·​Criticism

There’s a risk in posting follow-up thoughts as nested comments. The risk is that criticism chains won’t bubble up far enough.

If you want to add more information to an idea, I suggest revising it.

#5262​·​Dennis Hackethal, 4 days ago​·​Criticism

Progress does not require a complete ranking of every live explanation. If B has a fatal flaw while no fatal flaw is currently known in A or C, the flaw in B is enough to reject B while A and C both remain live. There does not need to be one property that all three explanations possess to different degrees.

Take the same explanation in two possible realities. The explanation has the same content and the same HTV in both, but it can correspond to one reality and fail to correspond to the other. HTV alone therefore cannot determine correspondence.

#5259​·​Benjamin DaviesOP, 4 days ago​·​Criticism

An explanation can be harder to vary than a rival and still contain a fatal flaw of another kind. Unless every possible fatal flaw is itself a form of ETV, HTV cannot comprehensively determine which explanation should be rejected.

Preference formation is a computational task. (#5255) To claim we’ve understood a computational task, we must have programmed it (Deutsch). Popper never programmed it, so he didn’t understand it.

(To his credit though, he got pretty technical in defining verisimilitude, logical vs. empirical content, etc.)

#5256​·​Dennis Hackethal, 4 days ago​·​Criticism

Consider that preference formation is an engineering problem:

And if it is, consider also that maybe it’s worth staying away from concepts like HTV, which we have no idea how to program:

The task is to write an algorithm that takes two ideas (eg in the form of strings of characters) and returns the preferable one.

How would one go about writing that?

I think it’d be fine to start with obviously wrong answers to that question and then incrementally correct errors. For example, an algorithm that favors the idea with fewer words. (A bit like Occam’s razor.) That’d be fine as long as one wrote working code.

Pavel Tichý and David Miller independently proved in 1974 that Popper’s definition of verisimilitude leads to a contradiction. Explanation:

Let us suppose that A and B are both false, and that A’s truth content exceeds B’s. Let a be a true sentence entailed by A but not by B. Let f be any falsehood entailed by A. Since A entails both a and f the conjunction, a&f is a falsehood entailed by A, and so part of A’s falsity content. If a&f were also part of B’s falsity content B would entail both a and f. But then it would entail a contrary to the assumption. Hence a&f is in A’s falsity content and not in B’s. So A’s truth content cannot exceeds B’s without A’s falsity content also exceeding B’s.

Suppose now that B’s falsity content exceeds A’s. Let g be some falsehood entailed by B but not by A, and let f, as before, be some falsehood entailed by A. The sentence f→g is a truth, and since it is entailed by g, is in B’s truth content. If it were also in A’s then both f and f→g would be consequences of A and hence so would g, contrary to the assumption. Thus A’s truth content lacks a sentence, f→g, which is in B’s. So B’s falsity content cannot exceeds A’s without B’s truth content also exceeding A’s. The relationship depicted in Diagram 4 simply cannot obtain: in this sense, that picture is an “impossible” one, like those in Escher’s famous drawings.

The idea ‘I’m located in a hemisphere’ is ‘easy to vary’ as to which hemisphere but it’s true, meaning it corresponds to reality.

HTV and correspondence are orthogonal.

Explanation A surviving criticism does not establish that explanation A is objective progress over explanation B. But the claim that one fatal flaw in explanation B is enough to reject explanation B does not depend on explanation A being objective progress. Rejecting explanation B and establishing explanation A as objective progress are separate claims.

#5251​·​Benjamin DaviesOP, 4 days ago​·​Criticism

One fatal flaw in B is enough to reject B. A does not also need to possess some opposite property that makes it the winner.

Something simple you could try is heavily dimming your computer and other devices and using strong red filters for the last few hours before bed.

Not just the standard night shift features, which are often far too weak. I mean making the screen properly red so that almost all of the blue and green light is removed.

You might be surprised by how dim you can make your devices while still being able to use them fine. You just need to give your eyes a minute to adjust. I routinely have my iPhone and MacBook on their dimmest settings.

Dimming or reddening the room lighting could help too. (Following up on #5243.)

This doesn't rule out blue light from other sources disturbing your ability to wind down and fall asleep.
