  Dennis Hackethal addressed criticism #3836.

The criterion for HTV applied to 2 explanation is not justificationism I think. It allows to say explanation A is better than explanation B, which is equivalent to: explanation B is worse than explanation A. So it is a relative claim about an explanation, relative to another, not versus some absolute criterion of goodness. Similar to a crucial test (e.g. Eddington): we refute Newton's theory and keep Einsteins, that is not a claim about the goodness of Einsteins theory, that theory merely has survived, it has not gotten "goodness points". It could be refuted always later on by any better theory, in which case we would drop it too.

So what? I didn’t mention an absolute criterion. My original criticism already applies to both relative and absolute criteria of quality (what you call “goodness”).

Similar to a crucial test …

But that’s exactly where HTV differs from Popper. Popper doesn’t give a theory points when it survives a crucial test. HTV does. From BoI chapter 1:

… testable explanations that have passed stringent tests become extremely good explanations …

  Dennis Hackethal addressed criticism #3819.

I think I've compressed other activities as much as possible. With the current job, I don't think I can increase focus on research any further. The concerns are over the tradeoffs of leaving the day job (finances, impact to employability, etc.).

#3819·Tyler MillsOP, 24 days ago

FWIW, if I was hiring, and I was looking at a resume of someone who always ‘played it safe’ and was very concerned about what others think, I wouldn’t hire them. Whereas I would hire someone who takes smart risks and cares about truth over popularity, even if they have a resume ‘gap’.

  Dennis Hackethal criticized idea #3820.

A related idea is to become more disciplined with my time, getting more out of the off days.

#3820·Tyler MillsOP, 24 days ago

Discipline means arbitrarily favoring one conflicting idea over another. ‘Arbitrarily’ meaning favoring without resolving the conflict.

You don’t actually know which idea is better, if any, before you resolve the conflict. So siding with one before then is irrational.

Instead of practicing discipline, practice resolving conflicts between ideas and thus finding common preferences with yourself: ideas you wholeheartedly agree with, have no reservations about.

Veritula helps you with that.

  Dennis Hackethal addressed criticism #3821.

So far this has proven ineffective, though a skill which could be improved. However, questions remain for me over whether self-disciplining is good, in general, and where to draw the line between coercion and healthy structure.

#3821·Tyler MillsOP, 24 days ago

skill

Self-discipline isn’t a skill. It’s an anti-skill and irrational.

  Dennis Hackethal addressed criticism #3823.

This brings us back to our conversation about discipline. Maybe we can recapitulate here, or maybe best done elsewhere. Lots of things are excruciating, like homework and exams; should I not have done them? Exercise as well. There seem to be problems which can only be solved by maintaining other problems..!
Should suffering be avoided? Not if it's useful..? I'm still conflicted about this.

#3823·Tyler MillsOP, 24 days ago

Should suffering be avoided? Not if it's useful..?

Self-coercion should be avoided, yes. When we coerce ourself, we are not creating knowledge and instead arbitrarily favoring one idea over another. If a part of you disagrees that something is useful, then don’t do it!

You can always find a common preference with yourself. Problems are soluble. Do not act on ideas that have pending criticisms.

#3823·Tyler MillsOP, 24 days ago

Just because lots of things are excruciating doesn’t mean life necessarily involves those things. Life doesn’t have to be difficult in this way.

You can find a passion, have fun 100% of the time, and never coerce yourself. (That’s an ideal we can fall short of – if we ‘only’ have fun 90% of the time, that’s still infinitely better than dooming ourselves to a life we hate.)

  Dennis Hackethal addressed criticism #3824.

I find this point irrefutable, aside from the risk being educated or calculated... Maybe it is those things...
What I would ultimately love to do is pivot into AGI research as a career, but when is pursuing that educated risk-taking vs fantasy?

#3824·Tyler MillsOP, 24 days ago

It would be fantasy/reckless if, for example, you were in your mid 40s, had a family to take care of, and had no savings.

#3824·Tyler MillsOP, 24 days ago

Why does it have to be a career? You could try it for a year or six months or whatever. If you don’t like it, you switch to something else. That’d be fine.

  Dennis Hackethal criticized idea #3825.

The Fountainhead is on my list. Listened to ‘The Simplest Thing in the World’. One message seems to be that one's creativity will continuously resist attempts to coerce it into doing something it doesn't want. A will of its own. I feel such resistance acutely at this current job, more so but no differently than during previous jobs and assignments, as we all have. But what is the import of the story to the present debate? My creative muse will continue fighting me so long as I'm trying to steer it towards other things? I have no doubt. The questions here are over what is practical, secure and strategic, all largely in the financial sense--or so I think. Where does one draw the line between passion and security? Maybe there is no general-purpose explanation. I will continue reflecting.

#3825·Tyler MillsOP, 24 days ago

You didn’t mark this as a criticism, but it sounds like one. Consider revising your idea to mark it as a criticism. (No changes to the text necessary for that.)

There’s nothing practical about working a job you hate. There’s nothing practical about fighting yourself.

Where does one draw the line between passion and security?

There’s no security in not pursuing your passion, and there’s no need to make this kind of tradeoff anyway.

  Dennis Hackethal revised criticism #3813.

It does sound like Deutsch thinks all these different criteria boil down to being about hard vs easy to vary, see #3807.

  Dennis Hackethal revised criticism #3807.

Not according to Deutsch. He says hard to vary is epistemologically fundamental, that all progress is based on it. For example, he phrases testability in terms of hard to vary (BoI chapter 1):

When a formerly good explanation has been falsified by new observations, it is no longer a good explanation, because the problem has expanded to include those observations. Thus the standard scientific methodology of dropping theories when refuted by experiment is implied by the requirement for good explanations.

For Deutsch, hard to vary is the key mode of criticism, not just one of many.

He also says that “good explanations [are] essential to science…” (thanks @tom-nassis for finding this quote). Recall that a good explanation is one that is hard to vary.

  Dennis Hackethal addressed criticism #3811.

Liberty responded (1:39:46) that that quote is misleading because it makes it sound like hard to vary is the only criterion people use when making decisions, which can’t be true. There are other criteria, like “consistency with data”, “logical consistency”, “fitting in with existing theories”, etc.

The quote may be false, but I don’t see how it’s misleading. I’m not quoting Deutsch in isolation or cherry-picking information or anything like that.

  Dennis Hackethal addressed criticism #3809.

I’m not saying hard to vary is a decision-making method. I’m saying it’s an integral part of Deutsch’s decision-making method. As I write in my article:

He argues that “we should choose between [explanations] according to how good they are…: how hard to vary.”

  Dennis Hackethal addressed criticism #3808.

Liberty said (at 1:38:39) hard to vary isn’t a method of decision-making. It’s a factor people take into account when they make decisions, but decision-making itself is a creative process.

#3808·Dennis HackethalOP, 24 days ago

I’m fine allowing user input to sidestep the creativity problem, see #3802.

  Dennis Hackethal addressed criticism #3707.

Deutsch contradicts his yardstick for understanding a computational task. He says that you haven’t understood a computational task if you can’t program it. His method of decision-making based on finding good explanations is a computational task. He can’t program it, so he hasn’t understood it.

  Dennis Hackethal addressed criticism #3719.

From my article:

[I]sn’t the difficulty of changing an explanation at least partly a property not of the explanation itself but of whoever is trying to change it? If I’m having difficulty changing it, maybe that’s because I lack imagination. Or maybe I’m just new to that field and an expert could easily change it. In which case the difficulty of changing an explanation is, again, not an objective property of that explanation but a subjective property of its critics. How could subjective properties be epistemologically fundamental?

  Dennis Hackethal revised criticism #3790.

But calling a theory ‘good’ sounds like an endorsement. Deutsch also writes (BoI chapter 10) that a “superb” theory is “exceedingly hard to vary”. Ultimately we’d have to ask him, but for now I think it’s fair to conclude that he means ‘hard to vary’ as an endorsement.

Ultimately we’d have to ask him, but for now, given the strength and positivity of those terms, I think it’s fair to conclude that he means ‘hard to vary’ as an endorsement.

  Dennis Hackethal revised criticism #3706.

Even if we allow creative user input, eg a score for the quality of an explanation, we run into all kinds of open questions, such as what upper and lower limits to use for the score, and unexpected behavior, such as criticisms pushing an explanations score beyond those limits.

@dirk-meulenbelt suggested in a space (at 21:30) that a bunch of epistemology is underspecified. There are many epistemological concepts (like criterion of democracy, falsifiability, etc.) that we don’t know enough about to express in code.

#3797·Dennis HackethalOP, 24 days ago

As I write in my article:

… Popper did formalize/specify much of his epistemology, such as the notions of empirical content and degrees of falsifiability. So why couldn’t Deutsch formalize the steps for finding the quality of a given explanation?

Deutsch’s yardstick applies to computational tasks. It’s not meant for other things. It’s not clear to me that the criterion of democracy is a computational task.
