As someone who researches and trains tacit knowledge, I appreciate this effort. Wish I had some better public resources!

Watching Simon from Cracking the Cryptic has given me a good feel for how to solve a hard Sudoku. Not exactly revolutionary, but there's some really clever logic there. (Watching anyone think aloud as they do a task is going to be great for tacit knowledge)

https://youtu.be/hAyZ9K2EBF0?si=65SYQQSpE0V_m3ah

A really good debate between two people is another thing I would recommend to watch. You can learn a lot about rationality and rhetoric from such debates.

For non-video resources, I recommend the book "Working Minds" which teaches how to do Cognitive Task Analysis (CTA) which is a major interviewing technique for uncovering tacit knowledge. I wish I knew a good resource where you could watch people use CTA!

As another non video resource, I'd also put in a good word for the LW community. Engaging with people in this sphere has taught me more about rationality than reading the Sequences. Though I think that engagement needs to be complimented by engagement with people who think differently from rationalists, as well.

TL;DR

Tacit knowledge is extremely valuable. Unfortunately, developing tacit knowledge is usually bottlenecked by apprentice-master relationships. Tacit Knowledge Videos could widen this bottleneck. This post is a Schelling point for aggregating these videos—aiming to be The Best Textbooks on Every Subject for Tacit Knowledge Videos. Scroll down to the list if that's what you're here for. Post videos that highlight tacit knowledge in the comments and I’ll add them to the post. Experts in the videos include Stephen Wolfram, Holden Karnofsky, Andy Matuschak, Jonathan Blow, Tyler Cowen, George Hotz, and others. 

What are Tacit Knowledge Videos?

Samo Burja claims YouTube has opened the gates for a revolution in tacit knowledge transfer. Burja defines tacit knowledge as follows:

Tacit knowledge is knowledge that can’t properly be transmitted via verbal or written instruction, like the ability to create great art or assess a startup. This tacit knowledge is a form of intellectual dark matter, pervading society in a million ways, some of them trivial, some of them vital. Examples include woodworking, metalworking, housekeeping, cooking, dancing, amateur public speaking, assembly line oversight, rapid problem-solving, and heart surgery.

In my observation, domains like housekeeping and cooking have already seen many benefits from this revolution. Could tacit knowledge in domains like research, programming, mathematics, and business be next? I’m not sure, but maybe this post will help push the needle forward.

For the purpose of this post, a Tacit Knowledge Video is any video that communicates “knowledge that can’t properly be transmitted via verbal or written instruction”. Here are some examples:

  • Neel Nanda, who leads the Google DeepMind mechanistic interpretability team, has a playlist of “Research Walkthroughs”. AI Safety research is discussed a lot around here. Watching research videos could help instantiate what AI research really looks and feels like.
  • GiveWell has public audio recordings of its Board Meetings from 2007–2020. Participants include Elie Hassenfeld, Holden Karnofsky, Timothy Ogden, Rob Reich, Tom Rutledge, Brigid Slipka, Cari Tuna, Julia Wise, and others. Influential business meetings are not usually made public. I feel I have learned some about business communication and business operations, among other things, by listening to these recordings.
  • Andy Matuschak recorded himself studying Quantum Mechanics with Dwarkesh Patel and doing research. Andy Matuschak “helped build iOS at Apple and led R&D at Khan Academy”. I found it interesting to have a peek into Matuschak’s spaced repetition practice and various studying heuristics and habits, as well as his process of digesting and taking notes on papers.

For information on how to best use these videos, Cedric Chin and Jacob Steinhardt have some potentially relevant practical advice. Andy Matuschak also has some working notes about this idea generally. @Jared Peterson, who "researches and trains tacit knowledge" recommends the book Working Minds "which teaches how to do Cognitive Task Analysis (CTA) which is a major interviewing technique for uncovering tacit knowledge."

How to Submit

Share links to Tacit Knowledge Videos below! Share them frivolously! These videos are uncommon—the bottleneck to the YouTube knowledge transfer revolution is quantity, not quality. I will add the shared videos to the post. Here are the loose rules:

  1. Recall a video that you’ve seen that communicates tacit knowledge—“knowledge that can’t properly be transmitted via verbal or written instruction”. A rule of thumb for sharing: could a reader find this video through one or two undirected YouTube searches? If not, share it.
  2. Post the title and the URL of the video.
  3. Provide information indicating why the expert in the video is credible. (However, don’t let this last rule stop you from sharing a video! Again—quantity, not quality.)[1]

To make the comments easy to navigate, please format your comment as follows:[2]

Domain: Programming, Game Development

Link: Programming livestream VODs

Person: Jonathan Blow

Background: Creator of Braid and The Witness.

Why: Blow livestreams himself coding games and creating a programming language. I imagine people who do similar things would find his livestreams interesting.

Finance

Disclaimer, copy-pasting a comment from @Max Entropy: 

[...] I'm skeptical of your recommendations (DeepFuckingValue and Martin Shkreli). The former made his money pumping-and-dumping meme stocks, and I get the impression the latter has been selected for fame (like recommending Neil deGrasse Tyson to learn physics).

In general, I think finding good resources in finance requires a much stronger epistemic immune system than nearly any other field! There's so much adverse selection, and charlatans can hide behind noisy returns and flashy slide decks for a very long time. I've worked at a top quant trader long enough to spot BS, and the KL-divergence between what competent looking YouTubers say and what actually works is extreme.

    • “American financial criminal and businessman. Shkreli is the co-founder of the hedge funds Elea Capital, MSMB Capital Management, and MSMB Healthcare, the co-founder and former CEO of pharmaceutical firms Retrophin and Turing Pharmaceuticals, and the former CEO of start-up software company Gödel Systems, which he founded in August 2016. [...] In 2017, Shkreli was charged and convicted in federal court on two counts of securities fraud and one count of conspiracy for activity unrelated to the Daraprim controversy. He was sentenced to seven years in prison and up to $7.4 million in fines.” (Wikipedia).
    • Anecdote from an experienced finance friend: "I haven't watched his videos, but remember a couple of (reasonable) people expressing surprise that they're legit introductions to financial modeling."
  • Aswath Damodaran, "Reading a 10K".
    • "Professor of Finance at the Stern School of Business at New York University, where he teaches corporate finance and equity valuation. [...] Damodaran is best known as the author of several widely used academic and practitioner texts on Valuation, Corporate Finance and Investment Management as well as provider of comprehensive data for valuation purposes" (Wikipedia).
    • Anecdote from an experienced finance friend: "Damodaran is an NYU prof who's super credible and well regarded for his practical tutorials on valuations and corporate finance, I used to refer to his blog often."
  • Roaring Kitty (DeepFuckingValue), trading livestreams.
    • Held a $53,000 investment that turned into a $50 million in Gamestop. Seems he got into some regulatory trouble. I'm not sure about the specifics of this (Wikipedia).

Review of: Elie Hassenfeld, Holden Karnofsky, Timothy Ogden, Rob Reich, Tom Rutledge, Brigid Slipka, Cari Tuna, Julia Wise: GiveWell's Public Board Meetings (2007–2020 have audio).

I'm a college student with only pretty low-stakes work experience. I listened to the first 5–10 meetings as I would a podcast last week. Some takeaways, emphasizing that I only just watched them last week:

  • It was interesting to follow the narrative of Holden and Elie getting started on the project. Like, anecdotes about people's experiences starting a startup are everywhere, but it was interesting hearing them actually talking about the struggles and business decisions they were making.
  • Holden worked 100h/wk in the first year; that's a lot of time spent on a project! (Then 60h/wk in the second, afaict.)
  • Interesting generally how assertive the business meetings were compared to everyday conversation.
  • I am familiar with GiveWell as a popular charity in the Rat/EA space, but I never really spent the time to understand the research methodology. It was interesting hearing the practical and strategic discussions between the founders and the board on the methodology. It also seemed to change every year in the f

"Mise En Place", "[i]nterviews and kitchen walkthroughs: Qualifies as tacit knowledge, in that people are showing what they're doing that you seldom have a chance to watch first-hand. Reasonably entertaining, seems like you could learn a bit here. Caveat: most of the dishes are really high-class/meat/fish etc. that you aren't very likely to ever cook yourself, and knowledge seems difficult to transfer.

Share links to Tacit Knowledge Videos below! Share them frivolously! These videos are uncommon—the bottleneck to the YouTube knowledge transfer revolution is quantity, not quality. I will add the shared videos to the post. Here are the loose rules:

Note: I strongly recommend either changing this post to be a question (so that answers are more easily broken out), or enforcing a standard structure to comments to make the comments-section easy to skim. One of the things that was IMO most important for the success of the Best Textbooks On Every Subject thread were the requirements that each submission compared at least 3 textbooks, and that Luke kept editing the best submissions back into the main post body.

Domain: PCB Design, Electronics Link: https://www.youtube.com/watch?v=ySuUZEjARPY Person: Rick Hartley Background: Has worked in electronics since the 60s, senior principal engineer at L-3 Avionics Systems, principal of RHartley Enterprises Why: Rick Hartley is capable of explaining electrical concepts intuitively, and linking them directly to circuit design. He uses a lot of stories and examples visually to describe what's happening in a circuit. I'm not sure it counts as Tacit Knowledge since this is lecture format, but it includes a bunch of things that you might not know you don't know, coming into the field. I never "got" how electrical circuits really work before watching this video, despite having been a hobbyist for years.

“Applied science” by Ben Krasnow.  A YouTube channel about building physics-intensive projects in a home laboratory.  Big ones are things like an electron microscope or a mass spectrometer, but the ones I find fascinating are smaller things like an electroluminescent display or a novel dye.  He demonstrates the whole process of scientific experiment— finding and understanding references, setting up a process for trying stuff, failing repeatedly, learning from mistakes, noticing oddities…  He doesn’t just show you the final polished procedure— “here’s how to make an X”.  He shows you the whole journey— “Here’s how I discovered how to make X”.

You seem very concerned that people in the videos should have legible symbols of success.  I don’t think that much affects how useful the videos are, but just in case I’m wrong, I looked on LinkedIn, where I found this self-assesment:

My core skillset includes electronic circuit design, PCB layout, mechanical design, machining, and sensor/actuator selection.

Perfect—thanks for the links! Will add this and the other submission to the post when I get the chance. The main driving motivation for this was seeing that The Best Textbooks on Every Subject received traction due to a similar mechanism. Another reason was wanting the tacit knowledge in the videos to be knowledge that's appealing to learn. I don't want the mechanism to stop the post from receiving submissions though; this resource-submission genre seems like the kind that benefits from network effects. If anyone has any thoughts as to whether the mechanism is useful or counterproductive, I would be curious to hear.

That was 13 years ago across an ocean of accelerating cultural change, institutional trust, and people maturing. I'm sure you can still find plenty of people who would use mechanisms like that, but I'm pretty sure it's going to be one of the less important considerations now.

Sofia Bue is a professional SFX sculptor; she works at Weta Workshop which is the most well-known special FX company in the world; they were responsible for SFX on Lord of the Rings. She also won the SFX category at the world Bodypainting championships at least once so I think she’s pretty indisputably world-class at it.

Her entire YouTube channel demonstrates a tonne of her tacit knowledge with respect to sculpting and SFX in general, but this is one good example of her showing her work on a small sculpture:

There's some great opportunities here to learn social skills for various kinds of high-performance environments (e.g. "business communication" vs Y Combinator office hours). 

Often, just listening and paying attention to how they talk and think results in substantial improvement to social habits. I was looking for stuff like this around 2018, wish I had encountered a post like this; most people who are behind on this are surprisingly fast learners, but didn't because actually going out and accumulating social status was too much of a deep dive.

Why: He and his wife bootstrapped themselves building their own cabin, then house, sell at a profit, rinse and repeat a few times. There are many, many videos of people building their own cabins, etc. Dave's are simple, clear, lucid, from a guy who's done it many times and has skin in the game.

Person: David J. Peterson

Background: Writer of many 'conlangs' (artificial languages) such as Dothraki from Game of Thrones

Why: 30+ part video-series about conlangs. In theory, it's meant as a resource to guide your own creation of a language. But it's also just a really good resource for absorbing how a linguist thinks about language. He talks about sounds/words/grammar, how they change over time, and what mechanisms are involved in that. IIRC he doesn't use very many tech... (read more)

Person: Anon

Background: He became pretty famous, and published a book of the same name

Why: from youtube description "Primitive technology is a hobby where you make things in the wild completely from scratch using no modern tools or materials. This is the strict rule. If you want a fire- use fire sticks, an axe- pick up a stone and shape it, a hut- build one from trees, mud, rocks etc. The challenge is seeing how far you can go without modern technology."

Sofia Bue is a professional SFX sculptor; she works at Weta Workshop which is the most well-known special FX company in the world; they were responsible for SFX on Lord of the Rings. She also won the SFX category at the world Bodypainting championships at least once so I think she’s pretty indisputably world-class at it.

Her entire YouTube channel demonstrates a tonne of her tacit knowledge with respect to sculpting and SFX in general, but this is one good example of her showing her work on a small sculpture:

Bryce Meyer (primary maintainer of TransformerLens, and software engineer with many years of experience) has a weekly coding stream event where he does live coding on TransformerLens--resolving bugs, adding features and tests, etc. I've found it to be useful!

You can find it in the Open Source Mechanistic Interpretability Slack, under the "code-sessions" channel (feel free to DM for an invite).

For the category Research/Studying, I recommend the series "Understanding Medical Research: Your Facebook Friend is Wrong" by F. Perry Wilson. Bite-sized videos explaining how to approach medical research people.

Last updated July 30 2020, so hopefully it reached many people during those confusing times and helped them strenghten their intellectual self defense. I wish I found out about it sooner, so that I could have recommended it earlier.
