Welcome to Veritula, Benjamin. Yes, the number may need to go up in the future.

Are you thinking of sun exposure to get enough vitamin D?

To be sure, I’m not a doctor, but because I have very fair skin, every dermatologist I’ve ever talked to has advised me to avoid the sun and instead take vitamin D supplements.

I don’t think the meta algorithm is necessary for the evolution of ideas. After all, there is no meta algorithm across minds, yet ideas (memes) evolve across minds. Inside a single mind, the meta algorithm is inherited from our non-creative ancestors, where (among other things) it acted as a fail safe against erroneous behaviors.

One of my previous comments notwithstanding, don’t be shy to mark ideas as criticisms whenever you point out a shortcoming. Otherwise, you won’t know later on which ideas you can adopt. In the context of Alzheimer’s, this sounds like a criticism.

In Darwinian evolution, competition and pruning are the same phenomena.

That doesn’t sound right. Not all competition is necessarily deleterious.

Wait, do you view the pruning as separate from the mere competition of ideas…?

Yes. When I say ‘pruning’, I’m referring to a specific mechanism of a meta algorithm in the mind. For more details, see my book A Window on Intelligence, I think chapter 5. There is no such meta algorithm in biological evolution.

That’s a valid point but doesn’t belong here. I have instead edited a related idea.

The pruning mechanism is part of it, but there’s more. Again, there’s also competition between ideas and even predatory behavior that can result in the elimination of ideas. All such phenomena taken together constitute natural selection in the mind.

… Rat Festers cite Popper and Deutsch as if they are infallible.

Shouldn’t it be ‘as if they were infallible’?

Hardly anyone reads those, and many of those who do forget.

I have speculated in the past that ideas compete for attention, but they also compete for any kind of memory, be it something like RAM or hard-disk memory. The RAM-like memory in the brain is presumably closely related to working memory, if not the same.

The reason most people don’t (permanently) run out memory (of either kind) isn’t that memory isn’t scarce but that there’s a pruning mechanism in the mind. And again, there’s competition. That competition can involve predatory ideas which disassemble the source code of other ideas and use it for themselves because that’s cheaper than to construct source code from scratch.

By the way, how is this a criticism? #2200 makes no mention of memory.

Everyone has scarce memory. Everyone’s brain has limited storage space.

Then you counter-criticize them for whatever you think they lack (which should be easy if they really aren’t good), thus addressing them and restoring the idea.

Then the idea should be revised to adjust or exclude the criticized part(s).

… I don’t yet know how to reconcile that, nor do I have a satisfactory alternative theory or criticism to offer.

Do #2140 and its children help as an alternative theory?

… I don’t yet know how to reconcile that, nor do I have a satisfactory alternative theory or criticism to offer.

You do know criticisms, see #2094.

We can criticize theories for lacking structure, resilience, depth, reach, etc. But again, if we want to avoid justificationism, theories that do have those attributes don’t get points for having them.

[L]abeling explanations as good or bad can itself be a form of positive argument.

Labeling them good, yes. But not labeling them bad.

You retain that freedom. Veritula has no power over you. Being irrational is your prerogative (as long as you don’t violate anyone else’s consent in the process). Just don’t pretend to yourself or others that you’re being rational when you’re not.

That would be a pending criticism.

Make a reasonable effort to make the criticism explicit so it can be brought into direct conflict with the parent idea and examined further. In the meantime, do consider it a pending criticism and don’t act on the parent idea. You can also submit a placeholder criticism saying something like ‘I have an inexplicit criticism of this idea.’
