A new episode of the Fluidity #audiobook #podcast: "Aspects Of Reasonableness - and - Reasonableness Is Meaningful Activity"

https://fluidity.libsyn.com/aspects-of-reasonableness-and-reasonableness-is-meaningful-activity

Aspects of reasonableness: A summary explanation of everyday reasonable activity, with a tabular guide and a concrete example. https://metarationality.com/reasonableness-aspects   Reasonableness is meaningful activity: Understanding concrete, purposeful activity is a prerequisite to understanding the formal rationality that depends on it. https://metarationali

Everyday reasonableness is the foundation of technical, formal, and systematic rationality. https://metarationality.com/reasonableness   This is not cognitive science - The Eggplant is neither cognitive nor science, although it seeks a better understanding of some phenomena cognitive science has studied. https://metarationality.com/cognitive-science   The ethnomethodological flip - A dram

Today Birdsite rolled out a feature in which every user can see how many times every tweet has been viewed. I created and shared a Tampermonkey userscript that hides this.

(Also, it hides the Trending Topics pane. Writing that part of the userscript was the first thing I did when I joined Twitter in 2021.)

My favorite static site generator, Spacebook, wouldn't build any of my websites ever since I got an M1 Mac with the new Apple chip. I did some digging; it took a couple of weeks of occasional work in my free time, but eventually I diagnosed where the problem was. As soon as I fixed it, I issued a pull request with a fix to the project.

I've benefited so much from that software over the years, that it's good to give back and contribute to open source.

You want to know the irony? I stayed away from Twitter from its inception until 2020, when I joined Twitter to engage in conversations with the authors I'm narrating in my audiobook. To my delight, I discovered Twitter's algorithm seems to work well to surround me with what I want.

Twitter is where I go to escape Mastodon.

It's time I admitted this. Hell is half-empty & half the devils are here.

I've run this Mastodon instance since 2019. This server is lovely. Mastodon's Federated timeline has now become what I used to avoid Twitter for.

Ironically, I can't shut it off, because as an admin, stemming the toxic firehose is literally my job.

A new episode of the Fluidity #audiobook #podcast: "Acting On The Truth, And Overcoming Post-Rationalist Nihilism"

https://fluidity.libsyn.com/acting-on-the-truth-and-overcoming-post-rationalist-nihilism

The conclusion of Part One of In The Cells Of The Eggplant: Taking Rationalism Seriously.   Acting On The Truth   Rationalist theories of action try to deduce optimal choices from true beliefs. This is rarely possible in practice.   https://metarationality.com/action-in-rationalism   Overcoming Post-Rationalist Nihilism   Realizing rationalism is wrong can be devastatin

On the Fluidity Forum Newsletter, I wrote about community formation, & why we have an attendance application process.

I addressed 3 ways for a rich textured social experience to collapse down to a sort of flat samey-ness:

Decoherence: a collapse into, basically, nothing

Vibe Cascade: a collapse into one vibe

Tribalism: a collapse into a mutually-reinforcing conflict process

The probability of green cheese: A thought experiment shows why probability theory and statistics cannot address uncertainty in general.   https://metarationality.com/small-world   Statistics and the replication crisis: The mistaken belief that statistical methods can tell you what to believe drove the science replication crisis.   https://metarationality.com/probabilism-crisis   You can support the podcast a

A new episode of the Fluidity #audiobook #podcast: Overdriving Approximation.

Approximation is a powerful technique, but is not applicable in all rational work, and so is not a good general theory of nebulosity.

https://fluidity.libsyn.com/probabilism-part-one

Probability theory seems an attractive foundation for rationalism—but it is not up to the job. https://metarationality.com/probabilism   Leaving the casino - Probabilistic rationalism encourages you to view the whole world as a gigantic casino—but mostly it is not like that. https://metarationality.com/probabilism-applicability   What probability can’t do - If probability theory were an epistemology, we’d wan

On this episode of the Fluidity #audiobook #podcast: When Will You Go Bald?

“Shades of gray” is sometimes a good way to think about nebulosity—the world’s inherent fuzziness—but not always.

On this episode of the Fluidity #audiobook #podcast: Are Eggplants Fruits?

Formal methods formally require impossibly precise definitions of terms. How do we use them effectively without that?

https://fluidity.libsyn.com/propositions-hypothesis-generation-and-unknown-unknowns

Three short chapters from In The Cells Of The Eggplant.   What can you believe? - Propositions are whatever sort of thing it is you can believe. Nothing can play that role; so we need a different understanding of belief.   https://metarationality.com/propositions   Where did you get that idea in the first place? - Rationalism does not explain where hypotheses, theori
