OC ACXLW Meetup #92 – ACX Everywhere Edition
Saturday, April 5, 2025 | 2:00 – 5:00 PM
Location: 1970 Port Laurent Place, Newport Beach, CA 92660
Host: Michael Michalchik – (michaelmichalchik@gmail.com | (949) 375-2045)
Welcome!
Hello, everyone! We’re excited to invite you to a special ACX Everywhere gathering, where we’ll explore two of Scott Alexander’s most influential and widely discussed essays: “Meditations on Moloch” and “I Can Tolerate Anything Except the Outgroup.” Whether you’re brand new to these pieces or have studied them before, we welcome your curiosity and ideas. Come ready for a relaxed but thought-provoking conversation—no prior expertise needed!
Readings & Links
1) Meditations on Moloch
- Text: Slate Star Codex (2014)
- Audio: YouTube Reading
2) I Can Tolerate Anything Except the Outgroup
- Text: Slate Star Codex (2014)
- Audio: Podcast link
(No worries if you can’t read or listen to them in full—just come with an open mind!)
Essay Overviews
“Meditations on Moloch”
- Coordination Failures: Scott frames “Moloch” as the destructive force that arises when people or institutions compete in ways that force everyone into a worse outcome—even if no one wants it.
- Arms Races & Zero-Sum: Examples include doping in sports, environmental exploitation, or endless overwork—everyone follows suit to stay competitive, with no single actor able to unilaterally stop.
- Escaping Moloch: Potential solutions often involve strong collective agreements or frameworks that break the cycle of “If I don’t, the other guy will.”
“I Can Tolerate Anything Except the Outgroup”
- Tribalism’s Double-Edge: Many of us consider ourselves tolerant—until we meet the group we truly can’t stand.
- Hypocrisy of Tolerance: We readily accept differences that don’t threaten us, but violently reject those we see as morally or culturally opposite.
- Real Implications: We may unify around certain enemies or narratives, ironically bridging differences only to channel hate toward a chosen outgroup.
Conversation Starters
1. Personal Moloch Moments
  - Where have you felt trapped in a “race to the bottom”—working longer hours, competing for scarce resources—and wished for a collective fix?
2. Is Outgroup Hatred Inevitable?
  - Do we each have a hidden “line in the sand” for what we refuse to tolerate? Where do you draw that line, and why?
3. Solutions to Moloch
  - How do we form strong enough coalitions or social norms to break vicious cycles? Is it purely top-down (regulation, laws) or bottom-up (individual choices, culture shifts)?
4. Tolerance vs. Complicity
  - When does “tolerating” become passivity or enabling something harmful? Conversely, is it easy to mistake rightful moral stances for “intolerant outgroup hatred”?
5. Interplay: Moloch & Outgroups
  - Do these two phenomena reinforce each other? For instance, do tribal rivalries hamper the coordination needed to defeat Moloch?
Join Us On April 5!
We look forward to a friendly deep dive into these essays and their relevance—from everyday life dilemmas to global issues. If you have any questions, just contact Michael (info above). Whether you’re new to Scott Alexander or a longtime SSC/ACX reader, come share your perspective—and let’s celebrate the spirit of ACX Everywhere together!

Hello Folks!
We are excited to announce the 41st Orange County ACX/LW meetup, happening this Saturday and most Saturdays thereafter.
Host: Michael Michalchik
Email: michaelmichalchik@gmail.com (For questions or requests)
Location: 1970 Port Laurent Place
(949) 375-2045
Date: Saturday, Sept 2, 2023
Time: 2 PM
This Saturday we are fortunate to have a special guest speaker, Professor Michael Rose, one of the leading researchers in the world on the evolution of aging and scientific strategies for health and life extension. His experiments and analysis point towards a heterodox approach to human life extension that has immediate implications on lifestyle and that provides a new scientific paradigm to develop advanced life extension technologies.

Please read the following outline of his research and approach to healthy long life, and bring your questions, comments, and criticisms for the presentation and lively discussion that will follow.
This link is the summary:

Embracing the power of evolution to stop aging | Dr. Michael Rose
- Walk & Talk: We usually have an hour-long walk and talk after the meeting starts. Two mini-malls with hot takeout food are easily accessible nearby. Search for Gelson’s or Pavilions in the zip code 92660.
- Share a Surprise: Tell the group about something unexpected that changed your perspective on the universe.
- Future Direction Ideas: Contribute ideas for the group’s future direction, including topics, meeting types, activities, etc.
Here is a summary from Claude 2:

Aging as a Decline in Adaptation
- Aging reflects a progressive decline in adaptation due to weakening natural selection after the onset of reproduction, not inherent biochemical deterioration. Some organisms exhibit no senescence, demonstrating that aging is not inevitable.
Experimental Evolution of Aging
- Shifting onset of reproduction in fruit flies quickly changes lifespan and aging rates, demonstrating the malleability of aging by altering natural selection.
Role of Natural Selection in Patterns of Aging
- Comparative biology reveals correlations between ecological mortality factors and aging rates, evidencing the role of natural selection in shaping aging.
Human Aging in Evolutionary Context
- Humans likely evolved slow aging due to reduced extrinsic mortality from tools, hunting, and sociality attenuating the age-dependent decline in the forces of natural selection.
Impact of Agriculture on Human Aging
- Agriculture initially decreased health but populations adapted genetically to cereal and milk diets, primarily during high selection pressure juvenile phases. Older adults retain poor adaptation to agriculture.
Cessation of Aging
- There is a late-life cessation of aging where mortality/fertility plateaus due to negligible natural selection. Some populations may exhibit early cessation, investigable with hunter-gatherer lifestyles and medicine. Experiments shifting cessation of reproduction alter timing of aging cessation in flies, demonstrating it is evolvable.
Antagonistic Pleiotropy
- Trade-offs between early reproduction and late survival due to antagonistic pleiotropy of genetic variants accelerate senescence. Natural selection favors sacrificing later health for early fertility due to asymmetric forces of natural selection declining with age.
Evolutionary Basis for Life Extension
- Evolutionary experimental research provides the strongest framework for understanding the plasticity of aging rates and cessation. Mainstream molecular damage theories inadequately explain aging. Aging should be understood as an evolvable decline in adaptation amenable to genetic and environmental manipulation.

Conversation Starter Readings:
Suggested readings for this week are these summaries. These readings are optional, but if you do them, think about what you find interesting, surprising, useful, questionable, vexing, or exciting.

1) Prediction Markets
An intro to the general idea of prediction markets from Wikipedia. I concentrated more on the theory and accuracy sections. Where do you think prediction markets should be applied? Under what sorts of circumstances do you expect them to fail? What sort of “moral hazards” might they create? Can they be used to replace certain forms of regulation like drug approval and speed limits?

https://en.wikipedia.org/wiki/Prediction_market

https://daily.jstor.org/how-accurate-are-prediction-markets/
2) For psychedelics:

I came across a video channel that does a good job describing the phenomenology of the psychedelic experience. This video covers the trippy topic of psychedelic entities.

Audio version:
https://unsong.libsyn.com/universal-love-said-the-cactus-person
This Journal article is interesting speculation on the role of psychedelics in human evolution. Not a hypothesis I generally favor but worth discussing. Did using psychedelics create a religious orientation to metaphysical themes that allowed new forms of culture to emerge that provided a selective advantage? Were cultural restrictions on the use of psychedelics necessary for larger coherent societies to form without too much lateral thinking? Are psychedelics a necessary catalyst for change and/or a disruptive factor in our current society? How will societies that allow widespread use of psychedelics compete against societies that don’t?

1) What is open-mindedness
2) Psychedelics.

B) We will also have the card game Predictably Irrational and frisbees. Feel free to bring your own favorite games or distractions. This is a pet-friendly park and meeting.

Conversation Starter Readings:
Suggested readings for this week are these summaries. These readings are optional, but if you do them, think about what you find interesting, surprising, useful, questionable, vexing, or exciting.

1) Openmindedness.
This week we will try a classic video from the Skeptic/Atheist movement. Questions to think about and discuss? Is this a good description of the reality of open-mindedness? Did it change how you thought about open-mindedness? What do you think are the essential elements of open-mindedness to rationality? Is skepticism necessary for openmindedness and when does it work against it?

Open-mindedness
And/or This SSC essay. “The Control group is out of control”. What are the upsides and downsides of calling paranormal studies the control group for the scientific method. Does this increase our ability to be open to correct ideas, and is it worth shutting the door on exhausted lines of investigation? Why do you think belief in psychic powers affects the results of apparently rigorously replicated experiments? What do you make of the results of the smart rat, dumb rat experiment? Did you realize that double-blind is often thrown around as a claim when the second blinding is poorly done or not done at all and what is the importance of blinding to open-mindedness?

Written The Control Group Is Out Of Control | Slate Star Codex
Audio The Control Group Is Out of Control [Classic]
2) For psychedelics:

We will dip back into some of the best descriptive research done in the 1960s on the phenomenology of psychedelics. Read chapter 1 of “The varieties of psychedelic experience.”This book has many good digests of different people’s reactions and experiences with psychedelics. What types of experience most interest you? What did you not know about? What potential applications come to mind after reading these experiences? Do you agree with the taxonomy that the authors create?

the varieties of psychedelic experience.pdf

This is an interview with an experienced PTSD researcher that has been involved with the cutting-edge of PTSD treatment research about MDMA therapy. I generally like what he has to say and find his perspectives useful. I will put one caveat, which is he gets really enthusiastic about a lot of things. He is a generally more optimistic person than me.

Bessel van der Kolk on MDMA assisted therapy for PTSD: More profound than anything we have done

Finally, here are a couple of short videos by a guy that has used a lot of different drugs and ruined his life with them. He at first enthusiastically endorsed MDMA, but it did not stop him from ruining his life with other drugs or properly addressing the deep psychological issues he had to face. Psychedelics are often not enough and can even be a distraction or copium and have their own abuse potential.

Conversation Starter Readings:
Suggested readings for this week are these summaries. These readings are optional, but if you do them, think about what you find interesting, surprising, useful, questionable, vexing, or exciting.

1) Prediction

Superforcasting is a review of experiments done about how well various types of experts do in predicting the future. Generalists tend to do better than specialists in prediction, but why? Groups tend to do better than individuals, but are there ways to improve the performance of groups even further? How can you train yourself to be better at prediction? How can you help others?

And this excerpt from Future Babble is a more critical look at prediction science.

https://www.nytimes.com/2011/03/27/books/review/excerpt-future-babble-by-dan-gardner.html

For psychedelics:

The tale of two receptors is an interesting speculation as to the underlying pharmacology of psychedelics. Hypothesizing that serotonin can both help us cope with the distress of a bad situation and help us look for creative ideas out of the old mental habits that can keep us trapped in a bad situation. Conventional antidepressants and atypical antipsychotics operate on the acceptance system, while psychedelics operate on the later, lateral thinking. Is this perspective useful? Oversimplified? Can it be made into a rigorous scientific idea, or is it just another evolutionary just-so story? What possible uses and hazards does this suggest for psychedelics?

″ There can’t be too many things that reduce the expected value of the future by 10%; if there were, there would be no expected value left. ”
This is the argument from consequences fallacy. There may be many things that could destroy the future with high probability and we are simply doomed BUT the more interesting scenario and a much better working assumption is that there potentially dangerous things that are likely to destroy the future IF we don’t seek to understand them and try to correct them by concerted effort as opposed to continuing on as we do now with teh level of effort and concern we have now.

on: How to Ignore Your Emotions (while also thinking you’re awesome at emotions)
It seems to me that one of the trickier parts of this issue is that you don’t know what you don’t know. You’ve got the places in your emotional landscape that you’re used to visiting, and that’s where your attention naturally goes when you try to do a self-assessment. Reminds me a bit of something I learned in adolescence that when you’re playing hide and seek, people are really bad at remembering to look up; I’ve even had a friend that eluded police chasing him in the park by simply getting out of immediate few and then climbing up into the foliage of a tree. He saw the police walk right underneath him.

How do you break outside of the familiar? I think there are several, at least.
1. Don’t hold yourself back from floundering around. Babies engage in Fairly random motions in order to learn how their body works. It’s a kind of search routine even if it does seem haphazard and pointless. A true random walk may not be optimal but it does tend to cover unfamiliar ground eventually.
2. Put yourself into situations that are unfamiliar and don’t shut yourself off from them. You don’t necessarily have to pick the most unpleasant or aversive things that you’ve never done. But there should be good and bad novelty, and probably a whole lot of just weird. Give yourself a little bit of time in the new place so that you know What feelings emerge after your initial wariness to new situations.
3. Spend quiet time with yourself, meditation or other reflective times and simply concentrate on feelings. Abstract emotions and just feelings in your body and look for the small things oh, the things that you would normally ignore and let them emerge. They may be the tip of an iceberg.
4. Look to those times in your life that you seemed to have a diminished range of emotions compared to what people are supposed to have in those situations. If you don’t know what people are supposed to have in those situations oh, you probably should read more classic fiction from a variety of authors. I suggest both male and female authors because for whatever reasons it seems that there are different parts of the emotional spectrum that get covered. A lot of the Nobel prize-winning authors are quite good explorers of The Human Condition. For me, I’ve enjoyed Hermann Hesse and Doris Lessing oh, a lot of people like William Faulkner and James Joyce.
