#36 - Analyzing Effective Altruism as a Social Movement
In what is hopefully the last installment of Vaden and Ben debate Effective Altruism, we ask if EA lies on the cultishness (yes, that's a word) spectrum. We discuss:
The potential pitfall of having goodness as a core value
Aspects of Effective Altruism (EA) that put it on the cultishness spectrum
Does EA focus on good over truth?
Ben's experience with EA
Making criticism a core value
How does one resist the allure of groupthink?
How to (mis)behave at parties
How would one create a movement which doesn't succumb to cult-like dynamics?
Weird ideas as junk food
Error Correction intro segment
Scott Alexander pointing out that Ivermectin works indirectly via:
There’s a reason the most impressive ivermectin studies came from parts of the world where worms are prevalent, he says. Parasites suppress the immune system, making it more difficult for the human body to fight off viruses. Thus, getting rid of worm infections makes it easier for COVID-19 patients to bounce back from the virus.

#35 - Climate Change III: Fossil Fuels
Come experience the thrill of the shill as we discuss the somewhat-controversial natural resource called "fossil fuels". In this episode, we drill deep into opto-pessimist Vaclav Smil's excellent book Oil: A Beginner's Guide, in what is possibly our only episode to feature heterodox Russian-Ukrainian science, subterranean sound waves, and that goop lady - what's her name? It's unbelievable, right?
We discuss:
The science behind fossil fuels: How they're made, found, processed, and used
Energy transitions and the shale gas revolution
Global oil dependence and human rights
The environmental costs of fossil fuels
Will we reach Peak Oil?
Why natural resources aren't milkshakes
The future of fossil fuels

Quotes
Modern life now begins and ends amidst the plethora of plastics whose synthesis began with feedstocks derived from oil - because hospitals teem with them. Surgical gloves, flexible tubing, catheters, IV containers, sterile packaging, trays, basins, bed pans and rails, thermal blankets and lab ware: naturally, you are not aware of these surroundings when a few hours or a few days old, but most of us will become all too painfully aware of them six, seven or eight decades later. And that recital was limited only to common hospital items made of polyvinylchloride; countless other items fashioned from a huge variety of plastics are in our cars, aeroplanes, trains, homes, offices and factories.
Oil: A Beginner's Guide, p.10
A free market has not been one of the hallmarks of the 150 years of oil’s commercial history. The oil business has seen repeated efforts to fix product prices by controlling either the level of crude oil extraction or by dominating its transportation and processing, or by monopolizing all of these aspects. The first infamous, and successful, attempt to do so was the establishment of Standard Oil in Cleveland in 1870. The Rockefeller brothers (John D. and William) and their partners used secretive acquisitions and deals with railroad companies to gain the control of oil markets first in Cleveland, then in the Northeast, and eventually throughout the US. By 1904 what was now known as the Standard Oil Trust controlled just over 90% of the country’s crude oil production and 85% of all sales.
Oil: A Beginner's Guide, p.32
Photochemical smog was first observed in Los Angeles in the 1940s and its origins were soon traced primarily to automotive emissions. As car use progressed around the world al] major urban areas began to experience seasonal (Toronto, Paris) or near-permanent (Bangkok, Cairo) levels of smog, whose effects range from impaired health (eye irritation, lung problems) to damage to materials, crops and coniferous trees. A recent epidemiological study in California also demonstrated that the lung function of children living within 500m of a freeway was seriously impaired and that this adverse effect (independent of overall regional air quality) could result in significant lung capacity deficits later in life. Extreme smog levels now experienced in Beijing, New Delhi and other major Chinese and Indian cities arise from the combination of automotive traffic and large-scale combustion of coal in electricity-generating plants and are made worse by periodic temperature inversions that limit the depth of the mixing layer and keep the pollutants near the ground.

#34 - Climate Change II: Growth, Degrowth, Reactions, Responses
In this episode Ben convinces Vaden to become a degrowther. We plan how to live out the rest of our lives on an organic tomato farm in Canada in December, sewing our own clothes and waxing our own candles. Step away from the thermostat Jimmy.
We discuss:
The degrowth movement
The basics of economic growth, and why it's good for developing economies in particular
How growth enables resilience in the face of environmental disasters
Why the environment is in better shape than you think
Availability bias and our tendency to think everything is falling apart
The decoupling of economic growth and carbon emissions
Energy dense production and energy portfolios
And we respond to some of your criticism of the previous episode, including:
Apocalyptic environmental predictions been happening for a while? Really?
Number of annual cold deaths exceed the number of annual heat deaths? Really?
Your previous episode was very human-centric, and failed to address the damage humans are causing to the environment. What say you?
Are we right wing crypto-fascists? (Answer: Maybe, successfully dodged the question)

On Degrowth
This would be a way of life based on modest material and energy needs but nevertheless rich in other dimensions – a life of frugal abundance. It is about creating an economy based on sufficiency, knowing how much is enough to live well, and discovering that enough is plenty.
In a degrowth society we would aspire to localise our economies as far and as appropriately as possible. This would assist with reducing carbon-intensive global trade, while also building resilience in the face of an uncertain and turbulent future.
Wherever possible, we would grow our own organic food, water our gardens with water tanks, and turn our neighbourhoods into edible landscapes as the Cubans have done in Havana. As my friend Adam Grubb so delightfully declares, we should “eat the suburbs”, while supplementing urban agriculture with food from local farmers’ markets.
- Samuel Alexander, Life in a 'degrowth' economy, and why you might actually enjoy it
It would be nice to hear it straight for once. Global warming is real, it’s here, and it’s mind-bogglingly dangerous. How bad it gets—literally, the degree—depends on how quickly the most profligate countries rein in their emissions. Averting catastrophe will thus require places like the United States and Canada to make drastic cutbacks, bringing their consumption more closely in line with the planetary average. Such cuts can be made more or less fairly, and the richest really ought to pay the most, but the crucial thing is that they are made. Because, above all, stopping climate change means giving up on growth. That will be hard. Not only will our standards of living almost certainly drop, but it’s likely that the very quality of our society—equality, safety, and trust—will decline, too. That’s not something to be giddy about, but it’s still a price that those of us living in affluent countries should prepare to pay. Because however difficult it is to slow down, flooding Bangladesh cannot be an option. In other words, we can and should act. It’s just going to hurt.
- Daniel Immerwahr, Growth vs the Climate
On Perennial Apocalypticism
My offices were so cold I couldn't concentrate, and my staff were typing with gloves on. I pleaded with Jimmy to set the thermostats at 68 degrees, but it didn't do any good.
- Paul Sabin, quoting Rosalynn Carter in The Bet
Mostafa K. Tolba, executive director of the United Nations environmental program, told delegates that if the nations of the world continued their present policies, they would face by the turn of the century ''an environmental catastrophe which will witness devastation as complete, as irreversible, as any nuclear holocaust.''
- New York Times, 1982
A senior U.N. environmental official says entire nations could be wiped off the face of the Earth by rising sea levels if the global warming trend is not reversed by the year 2000. Coastal flooding and crop failures would create an exodus of "eco-refugees", threatening political chaos, said Noel Brown, director of the New York office of the U.N. Environment Program, or UNEP. He said governments have a 10-year window of opportunity to solve the greenhouse effect before it goes beyond human control."
- AP News, 1989
On Environmental Conservation
It’s not the case that humankind has failed to conserve habitat. By 2019, an area of Earth larger than the whole of Africa was protected, an area that is equivalent to 15 percent of Earth’s land surface. The number of designated protected areas in the world has grown from 9,214 in 1962 to 102,102 in 2003 to 244,869 in 2020.
- Michael Shellenburger, Apocalypse Never, p.75
Thanks to habitat protection and targeted conservation efforts, many beloved species have been pulled from the brink of extinction, including albatrosses, condors, manatees, oryxes, pandas, rhinoceroses, Tasmanian devils, and tigers; according to the ecologist Stuart Pimm, the overall rate of extinctions has been reduced by 75 percent.
- Steven Pinker, Enlightenment Now, p.160
On Environmental Optimism
Following China’s ban on ivory last year, 90% of Chinese support it, ivory demand has dropped by almost half, and poaching rates are falling in places like Kenya. WWF
The population of wild tigers in Nepal was found to have nearly doubled in the last nine years, thanks to efforts by conservationists and increased funding for protected areas. Independent

#33 (C&R Series, Ch. 3) - Instrumentalism and Essentialism
Galileo vs the church - whose side are you on? Today we discuss Chapter 3 of Conjectures and Refutations, Three Views Concerning Human Knowledge. This is a juicy one, as Popper manages to simultaneously attack both philosophers and physicists, as he takes on instrumentalism and essentialism, two alternatives to his 'conjecture and refutation' approach to knowledge. We discuss:
The conflict between Galileo and the church
What is instrumentalism, and how did it become popular?
How instrumentalism is still in vogue in many physics departments
The Problem of Universals
The essentialist approach to science
Stars, air, cells, and lightning
"What is" vs "How does" questions
The relationship between essentialism and language, and its influence on politics.
Viewing words as instruments
See More:
Instrumentalism: https://en.wikipedia.org/wiki/Instrumentalism
Essentialism: https://en.wikipedia.org/wiki/Essentialism
The problem of universals: https://en.wikipedia.org/wiki/Problem_of_universals
Quotes:
Few if any of the physicists who have now accepted the instrumentalist view of Cardinal Bellarmino and Bishop Berkeley realize that they have accepted a philosophical theory. Nor do they realize that they have broken with the Galilean tradition. On the contrary, most of them think that they have kept clear of philosophy; and most of them no longer care anyway. What they now care about, as physicists, is (a) mastery of the mathematical formalism, i.e. of the instrument, and (b) its applications; and they care for nothing else.
-- C&R, Page 134
Thus my criticism of essentialism does not aim at establishing the non-existence of essences; it merely aims at showing the obscurantist character of the role played by the idea of essences in the Galilean philosophy of science (down to Maxwell, who was inclined to believe in them but whose work destroyed this belief). In other words my criticism tries to show that, whether essences exist or not, the belief in them does not help us in any way and indeed is likely to hamper us; so that there is no reason why the scientist should assume their existence.
-- C&R, Page 141.
But they are more than this, as can be seen from the fact that we submit them to severe tests by trying to deduce from them some of the regularities of the known world of common experience i.e. by trying to explain these regularities. And these attempts to explain the known by the unknown (as I have described them elsewhere) have immeasurably extended the realm of the known. They have added to the facts of our everyday world the invisible air, the antipodes, the circulation of the blood, the worlds of the telescope and the microscope, of electricity, and of tracer atoms showing us in detail the movements of matter within living bodies. All these things are far from being mere instruments: they are witness to the intellectual conquest of our world by our minds.
But there is another way of looking at these matters. For some, science is still nothing but glorified plumbing, glorified gadgetmaking—‘mechanics’; very useful, but a danger to true culture, threatening us with the domination of the near-illiterate (of Shakespeare’s ‘mechanicals’). It should never be mentioned in the same breath as literature or the arts or philosophy. Its professed discoveries are mere mechanical inventions, its theories are instruments—gadgets again, or perhaps super-gadgets. It cannot and does not reveal to us new worlds behind our everyday world of appearance; for the physical world is just surface: it has no depth. The world is just what it appears to be. Only the scientific theories are not what they appear to be. A scientific theory neither explains nor describes the world; it is nothing but an instrument.
-- C&R, Page 137-8.

#32 - Climate Change I: Initial Thought-Crimes
After the immensely positive response to our previous episode on the Weinstein brothers - thanks @robertwiblin! - we thought we would keep giving the people what they want, and what they want is a long discussion on climate change. Specifically, the subject for today is: "The State of the Climate Debate". We touch on:
The near perfect partisan split on climate change
Will there be a climate apocalypse?
The promise of nuclear energy as a solution
The limitations of renewables
Energy portfolios
The rebound effect
Degrowth economics
Activist tactics and fear mongering
Whether The Environment has become A Deity in environmentalist circles
We expect very little pushback on this episode.

But real climate solutions are ones that steer these interventions to systematically disperse and devolve power and control to the community level, whether through community-controlled renewable energy, local organic agriculture or transit systems genuinely accountable to their users.

Even if nuclear power were clean, safe, economic, assured of ample fuel, and socially benign, it would still be unattractive because of the political implications of the kind of energy economy it would lock us into.

#31 - The Fall of the Weinstein Republic
Today we take your twitter questions before doing a deep dive into the Weinstein fiasco (Bret and Eric, not Harvey.) If you haven't heard of the Weinstein's before, then we suggest you run away before we drag you down into a rabbit hole filled with acronyms, anti-vaxxers, and theories of ... everything? anything? literally anything at all?
Topics we touch:
We take your twitter questions!
Filos with a weird one: I have a weird one that could be fun. It seems to me that the idea that we could upload our minds to a computer is nonsense. I agree with Kastrup that what we would upload is a description of our minds and a description of something is not that something. And it seems this desire to immortality is the nerd's reinvention of God via AGI, and heaven via uploading a mind to a silicon substrate. Where do you fall in this mind uploading fantasy? possible? Religious impulse? Reasonable?
Dan would like us to talk about: The pervasive skepticism that seems to run through much the Popperian and Crit Rat communities regarding nonhuman animals’ capacity to suffer, particularly factory farmed animals.
Karl is interested in: I'm interested in the meta-question of why that issue seems to split the community in two. Why hasn't one view become the dogmatic truth yet as it seems to have in most other communities?
WTF is up with Bret and Eric Weinstein
The allure of reflexive contrarianism
The (horrible! awful! stop it!) tendency of academics to use convoluted language to impress their non-peers
The notion of "secular gurus" and what distinguishes a secular guru from a person with a large platform
And the special responsibility of researchers to communicate clearly.

Quotes:
Every intellectual has a very special responsibility. He has the privilege and the opportunity of studying. In return, he owes it to his fellow men (or 'to society') to represent the results of his study as simply, clearly and modestly as he can. The worst thing that intellectuals can do - the cardinal sin - is to try to set themselves up as great prophets vis-à-vis their fellow men and to impress them with puzzling philosophies. Anyone who cannot speak simply and clearly should say nothing and continue to work until he can do so.

#29 - Some Scattered Thoughts on Superforecasting
We're back! Apologies for the delay, but Vaden got married and Ben was summoned to be an astronaut on the next billionaire's vacation to Venus. This week we're talking about how to forecast the future (with this one simple and easy trick! Astrologers hate them!). Specifically, we're diving into Philip Tetlock's work on Superforecasting.
So what's the deal? Is it possible to "harness the wisdom of the crowd to forecast world events"? Or is the whole thing just a result of sloppy statistics? We believe the latter is likely to be true with probability 64.9% - no, wait, 66.1%.
Intro segment:
"The Sentience Debate": The moral value of shrimps, insects, and oysters
Relevant timestamps:
10:05: "Even if there's only a one in one hundred chance, or one in one thousand chance, that insects are sentient given current information, and if we're killing trillions or quadrillions of insects in ways that are preventable or avoidable or that we can in various ways mitigate that harm... then we should consider that possibility."
25:47: "If you're all going to work on pain in invertebrates, I pity you in many respects... In my previous work, I was used to running experiments and getting a clear answer, and I could say what these animals do and what they don't do. But when I started to think about what they might be feeling, you meet this frustration, that after maybe about 15 years of research, if someone asks me do they feel pain, my answer is 'maybe'... a strong 'maybe'... you cannot discount the possibility."
46:47: "It is not 100% clear to me that plants are non sentient. I do think that animals including insects are much more likely to be sentient than plants are, but I would not have a credence of zero that plants are sentient."
1:01:59: "So the hard problem I would like to ask the panel is: If you were to compare the moral weight of one ant to the moral weight of one human, what ratio would you put? How much more is a human worth than an ant? 100:1? 1000:1? 10:1? Or maybe 1:1? ... Let's start with Jamie."

#28 (C&R Series, Ch. 9) - Why is Logic Applicable to Reality?
Why do logic and mathematics work so well in the world? Why do they seem to describe reality? Why do they they enable us to design circuit boards, build airplanes, and listen remotely to handsome and charming podcast hosts who rarely go off topic?
To answer these questions, we dive into Chapter 9 of Conjectures and Refutations: Why are the Calculi of Logic and Arithmetic Applicable to Reality?.
But before we get to that, we touch on some of the good stuff: evolutionary psychology, cunnilingus, and why Robin is better than Batman.

“In so far as a calculus is applied to reality, it loses the character of a logical calculus and becomes a descriptive theory which may be empirically refutable; and in so far as it is treated as irrefutable, i.e. as a system of logically true formulae, rather than a descriptive scientific theory, it is not applied to reality.”

There are many overused internet keywords that could be associated with this conversation, but none of them quite seem right. So here's a poem instead:
The Ogre does what ogres can,
Deeds quite impossible for Man,
But one prize is beyond his reach:
The Ogre cannot master speech.
About a subjugated plain,
Among its desperate and slain,
The Ogre stalks with hands on hips,
While drivel gushes from his lips
