The Best Tacit Knowledge Videos on Every Subject
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:
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.
Post the title and the URL of the video.
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]

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.
Martin Shkreli, Finance Lessons.
“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.”

Requests Thread. Post requests for tacit knowledge videos below this comment.
This thread also serves as a memory jogger for those who might have seen videos of the requested types.
InDesign! Or anything on page layout / publishing / how to make a pretty and well formatted book
I would be interested in more studying/learning videos. I found Andy Matuschak’s very interesting.
@Yoav Ravid: “I’d be interested in tacit knowledge videos about writing, if anyone knows any.”
I would find forecasting videos would be interesting to watch.
There’s this intro series by @Alex Lawsen.
Fundraising videos?
@habryka / @mods—would it be possible to pin (1) the ‘Review Thread’ and (2) this thread?
I think these will be the two most valuable comments on this post. The comment video submissions are a bit cluttered due to embeds and submissions are more accessible/navigatable through the OP.
Done.
Any chance you could pin the ‘Updates Thread’ too?
Done.
Meal prepping Tacit Knowledge Videos?
I would be interested in hearing the thought processes behind experienced interviewers.
For example, Tyler Cowen has a few blog posts speaking to his interviewing tacit knowledge.
If there was something like this in a more information-dense video format, I would be keen to watch it.
this interview between alexey guzey and dwarkesh patel gets into it a bit!
Interior design, please! I can never figure out which pieces of furniture will actually look good together or flow nice in a home. Especially when combined with lighting and shelves and art.
Networking, Relationship building, both professional and personal, I’m sure there are overlaps. And echoing another request: Sales
Sales tacit knowledge videos?
Tacit Knowledge Videos of eurogames.
At one point I had watched a video on YouTube like Upright Citizens Brigade—ASSSSCAT Improv, but with the ASSSSCAT actors rewatching their performance and providing commentary on their thought processes. I would be delighted if anyone knows the original video or has a similar video they know of.
Updates Thread. Below are ~monthly updates with lists of new tacit knowledge videos so you don’t have to scroll through the list again to find new videos.
You can subscribe to the Tacit Knowledge Video Updates Substack to have these emailed to you or sent to an RSS feed (https://tacitknowledgevideos.substack.com/feed).
Below are the new tacit knowledge videos added to the post since mid-April, 2024.

I’ve had a busy past few months (if a three-month meditation retreat counts as busy). There have been more videos submitted than videos added to the post in this batch. I will add these in the coming months.
Review Thread. Post reviews of content linked above below this comment.
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 first three years (I haven’t watched beyond the first three years).
Interesting from a marketing and fundraising perspective to watch as GiveWell, which seems to have found its market now, tested and went about finding one.
Interesting to instantiate generally ‘what are board meetings? who are the people in board meetings? what are their skills?’
Discussions around productivity were interesting. I’ve learn ‘productivity’ skills to improve my time spent studying and working on projects. I was surprised to hear that this is something that was talked about in board meetings, let alone for 10s of minutes.
I would be curious to hear a review from someone with more business experience. If you are to go about watching them, I recommend starting from the beginning. I’ve tried watching a few more recent recordings before this past week and found them less engaging, maybe due to me having less context about the organization.
“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.
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.
Thank you for the recommendation! I think I agree. I will be editing the comments back into the body, but I think it would be useful for the comments to be more legible.
For those reading this, here is the format I recommend (I’ve since edited this recommendation into the 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:
<begin copied text>
I specialize in the design and construction of electromechanical prototypes. My core skillset includes electronic circuit design, PCB layout, mechanical design, machining, and sensor/actuator selection. This allows me to implement and test ideas for rapid evaluation or iteration. Much of the work that I did for my research devices business included a fast timeline, going from customer sketch to final product in less than a month. These products were used to collect data for peer-reviewed scientific papers, and I enjoyed working closely with the end user to solve their data collection challenges. I did similar work at Valve to quickly implement and test internal prototypes.
Check out my youtube channel to see a sample of my personal projects:
http://www.youtube.com/user/bkraz333
<end copied text>
I’m gonna quote from this article about why you’d prefer to learn tacit knowledge from “believable people” i.e. those who have 1) a record of at least 3 different successes and 2) have great explanations of their approach when probed.
Domain: Physics
Link: “Applied Science”
Person: Ben Krasnow
Background: From his LinkedIn: “I specialize in the design and construction of electromechanical prototypes. My core skillset includes electronic circuit design, PCB layout, mechanical design, machining, and sensor/actuator selection.

(I’ve since changed the formatting standards for this post; I hope you don’t mind me reposting your information to make it more legible for new readers.)
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.
and while I’m here, i also curate something like this. ben krasnow is only the best entry point into a wider world. This list was my best attempt recently, it was particularly aimed at getting programmers into physical engineering topics, trying to removing learned helplessness around it and making the topic feel like something it’s possible to engage with. https://gist.github.com/taygetea/1fcc9817618b1008a812e6f2c58ca987
Thanks sharing sharing this! I’ve added one and intend to add more of them when I have more time.
For home cooking I would like to recommend J. Kenji Lopez-Alt (https://www.youtube.com/@JKenjiLopezAlt/videos). He’s a well-loved professional chef who writes science-y cooking books, and his youtube channel is a joy because it’s mostly just low production values: him in his home kitchen, making delicious food from simple ingredients, just a few cuts to speed things up.
Thanks for sharing! Added. I’d be curious if anyone has this but for meal prepping instead of cooking a single meal.
It should at least be mentioned that Shkreli is a convicted fraudster.
Agreed and added.
I’d be interested in tacit knowledge videos about writing, if anyone knows any.
I’ve since created a requests thread where comments like these can go. Maybe the requests can serve as memory joggers for readers who’ve seen a certain type of Tacit Knowledge Video but don’t recall the video after first reading the post.
Domain: Various: Startups, Events, Project Management, etc
Link: Manifund, Manifold, and Manifest {2023, 2024: meeting notes, docs, budget}
Person: Various: generally, the Manifold, Manifund, and Manifest teams
Why: This isn’t a video, but it’s probably relevantly close. All Manifold-sphere things are public — all meeting notes, budgets/finances, strategy docs, etc. I think that someone could learn a lot of tacit knowledge based on how the Manifold-sphere teams work by skimming e.g. our meeting notes docs, which are fairly comprehensive/extensive.
Love this idea, and +1 on Jon Gjengset and Neel Nanda.
For finance though, 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.
My recommendations would be:
Blogs with great tacit knowledge: bitsaboutmoney.com, thediff.co, Money Stuff
Trustworthy news sources: Financial Times, Bloomberg News, Reuters
Other recommendations:
Git version control: Scott Chacon’s So You Think You Know Git videos
Thanks for the Git recommendation; added!
Thanks for the feedback! I too am skeptical of the finance videos, agreeing that the video probably came across my radar due to the figures being popular rather than displaying believable tacit knowledge.
I’ve gone back and forth on whether to remove the videos from the list or just add your expert anecdata as a disclaimer on the videos. In the spirit of quantity vs. quality, I’m leaning toward keeping the videos on the list.
Update: added the disclaimer.

Promoted to curated: The original “The Best Textbooks on Every Subject” post was among the most valuable that LessWrong has ever featured. I really like this extension of it into the realm of tacit knowledge videos, which does feel like a very valuable set of content that I haven’t seen curated anywhere else on the internet.
Thank you very much for doing this! And I hope this post will see contributions for many months and years to come.
Glad to see that people find the post useful! I hope it will see many future contributions as well. In case interesting to anyone, I’ve just put together a
google formSubstack (edited 5.6.24) to create an email list for those who would like to be sent lists of newly added videos every month or so.Domain: Singing (especially theatre/musicals, but not just)

Why: Philip Quast’s has probably done the best performance of Javert, and in the interview he goes through the process of how he figures out how to sing his songs.
Thanks! Added.
For math I’d like to submit this series: “A hard problem in elementary geometry” by fields medalist
Timothy Gowers. It’s a 6 part series where each part is about an hour long, of him trying to solve this easy-seeming-but-actually-very-difficult problem.
Thanks! Added.
Sir Gowers actually has a number of playlists around thinking about problems in real time; haven’t looked at them myself, but may be worthwhile to mention that this series is one instance of multiple playlists of the same type, each focused on its own domain.
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:

A few channels on parenting and homemaking:
Lisa from a YouTube channel called Farmhouse on Boone walks through her house and discusses what items she keeps where and why, and how she avoids clutter. She is a mom of 8 with a successful YouTube channel (successful enough that her husband quit his job and now helps with the channel and homeschooling).
https://m.youtube.com/watch?v=5slnHqMG22Q&pp=ygUjZmFybWhvdXNlIG9uIGJvb25lIG1pbmltYWxpc3QgaG91c2U%3D
This woman (whose name I don’t know) is a Christian mom who homeschools her 8 children. In this video she walks through a day in the life of her family. I know less about any metrics of success, except that she reports that her family is easy to run and enjoyable for her.
https://m.youtube.com/watch?v=j9YWQefBt1o&pp=ygUrRGF5IGluIHRoZSBsaWZlIGhvbWVzY2hvb2wgZmFtaWx5IGNocmlzdGlhbg%3D%3D
Thanks! Added.
Interesting, got anymore? Especially for toddlers and so on, or would you go through everything those women have uploaded?
Lisa doesn’t post much about parenting toddlers; she posts a bit about birth and newborns but the focus of her channel is more on cooking and homemaking and less on parenting IMO. I don’t know enough about the other woman’s channel to evaluate; I’ve only watched a few.
A parent friend recommended the RIE parenting philosophy, and RIE has several demo videos of parents interacting with their kids according to the principles. I’ve watched a few; I think they’re searchable by keyword.
Thanks!
an all around handyman (the Essential Craftsman on youtube) talking about how to move big/cumbersome things without injuring yourself:
the same guy, about using a ladder without hurting yourself:
He has many other “tip” style videos.

Juggling: Anthony Gatto’s juggling routine from 2000. Anthony Gatto holds several juggling world records. This routine is infamous in the juggling world (here’s a decent juggler commenting on it). As well as the fact that he gave up juggling to work with concrete instead (because it pays the bills). Here’s more context on Gatto and his routine (the guy picking up the balls for him in the video is his father, for example):

I don’t have one video to recommend for each topic, but YouTube is a great source of videos of giving birth and of related activities like breastfeeding, babywearing, and even holding a baby.
I think simply searching ‘birth video’ or ‘homebirth’, ‘hospital birth’ or something similar gets you enough such videos, and watching a bunch of different women give birth is probably better than watching a single ‘expert’.
Thanks! I didn’t add this as I couldn’t readily think of a way to make it fit the format. But I’ve upvoted the comment to make it more visable.
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. There’s no reason that being-pleasant-to-talk-with should be arcane knowledge (at least not here of all places).
Did you find anything interesting in 2018? Did you use it, and, if yes, how’d it go?
I think speedrunning videos should count, though many people may not find them useful. Likewise for watching high level competitions.
Agreed. I added the link to speedrun.com/games to the post. From there readers can navigate to individual games and their respective leaderboards, click on a player, and watch the player’s speedrun YouTube video.
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.
Thanks Jared! I’ve added the channel as well as the book recommendation to the post.
This is not a video, but I think it counts as a useful example of tacit knowledge.
Domain: Google-fu

Person: Gwern
Background: Creator of consistently thorough essays
Why: Gwern talks you through what he did to hunt down obscure resources on the internet and in the process shows you how much dakka you could bring to bear on googling things you don’t know.
Thanks!
If there were a bunch of videos of people Google-fu-ing like this, I wouldn’t add this article to the post.
However, since this is one of the few good resources on Google-fu that I know of, I’m adding it to the post. Despite it not being a video.
[pasting a comment of mine on Zvi’s recent monthly roundup]
If anyone has anecdotes as to why they think the videos have been useful to them I’d be curious to hear. I’m still unsure of their benefit; the interest could just be novelty/insight-porn (Andy Matuschak speculates something in this direction, though he too seems ambivalent). I wrote the post partly as a test to see if there is much use.

Esther Perel’s podcast called ‘Where Shall We Begin?’ where she does a live couples’ therapy session with a guest couple.

The LessWrong Review runs every year to select the posts that have most stood the test of time. This post is not yet eligible for review, but will be at the end of 2025. The top fifty or so posts are featured prominently on the site throughout the year.
Hopefully, the review is better than karma at judging enduring value. If we have accurate prediction markets on the review results, maybe we can have better incentives on LessWrong today. Will this post make the top fifty?
Here’s a weird one. The YouTube channel of Andrew Camarata communicates a great deal about small business, heavy machinery operation and construction. Some of it he narrates what he’s doing, but he mostly just does it, and you say “Oh, I never realized I could do that with a Skid Steer” or “that’s how to keep a customer happy”. Lots of implicit knowledge about accomplishing heavy engineering projects between an hour and a week long. Of course, if you‘re looking for lessons that would be helpful for an ambitious person in Silicon Valley, it will only help in a very meta way.
He has no legible success that I know of, except that he’s wealthy enough to afford many machines, and he’s smart enough that the house he designed and built came out stunning (albeit eccentric).
A similar channel is FarmCraft101, which also has a lot of heavy machinery, but more farm-based applications. Full of useful knowledge on machine repair, logging and stump removal. The channel is nice because he includes all his failures, and goes into articulate detail on how he debugged them. I feel like learned some implicit knowledge about repair strategies. I particularly recommend the series of videos in which he purchases, accidentally sets on fire, and revives an ancient boom lift truck.
No legible symbols of success, other than speaking standard American English like he’s been to college, owning a large farm, and clearly being intelligent.

I particularly recommend the series of videos in which he purchases, accidentally sets on fire, and revives an ancient boom lift truck.

Domain: Small Business, Heavy Machinery Operation, Construction
Link: Andrew Camarata
Background: He has no legible success that I know of, except that he’s wealthy enough to afford many machines, and he’s smart enough that the house he designed and built came out stunning (albeit eccentric).
Why: The YouTube channel of Andrew Camarata communicates a great deal about small business, heavy machinery operation and construction. Some of it he narrates what he’s doing, but he mostly just does it, and you say “Oh, I never realized I could do that with a Skid Steer” or “that’s how to keep a customer happy”. Lots of implicit knowledge about accomplishing heavy engineering projects between an hour and a week long. Of course, if you‘re looking for lessons that would be helpful for an ambitious person in Silicon Valley, it will only help in a very meta way.

It seems like Guzey has changed his mind about a bunch of things, including needing all those huge monitors.
Makes me think this video is no longer relevant.
Blogpost
I’ve added this as a note. Thanks!
This is one of the most useful articles on acquiring knowledge.
Thanks for the kind words! I’d be curious to hear more about what makes you think that!
Into Quilez is a phenomenal computer graphics programmer. His videos show him making works of art from pure code without importing textures. https://youtube.com/@InigoQuilez?si=P468pB_dPf_Icq57
Thanks! Added.
I was enthusiastic about the title of this post, hoping for something different from the usual lesswrong content, but disappointed by most of the examples. In my view if you take this idea of learning tacit knowledge with video seriously, it shouldn’t affect just how you learn, but what you learn, rather then trying to learn book subjects by watching videos.
If you have recommendations, post them! I doubt the author tried to filter the subjects very much by “book subjects” it’s just what people seem to have found good ones so far.
Thanks for the feedback! I’d be curious to hear more about (1) what subjects you’re referring to and (2) how learning tacit knowledge with video has changed your learning habits (if your view here is based on your own experience).
You’ve already mentioned cooking as an example and this is definitely something I’d like to imiprove in. I looked up how to crack eggs:

https://www.youtube.com/user/advocatttt (Russian narration)
Person: Max Egorov
Background: Unknown
Why: Bushcraft and off-grid craftsmanship. Advoko has a site in the woods near Lake Ladoga in Russia where he films himself building various improvements by hand with local materials. Very competent craftsman, professional touch with no hype.
Thanks! Added.
Domain: Business & Business Communication, Mastering Difficult Conversations, Coaching
Link: Misha Glouberman—Recorded Coaching Sessions
Person: Misha Glouberman (That’s me)
Background: Consultant, Business Coach, and Co-Author of The Chairs Are Where The People Go.
Why:
While there’s lots of reading materials on this kind of work, this recording offers the unique opportunity to actually listen and experience the coaching work and learnings happening in real-time. The concepts discussed can be applied to work-related, difficult conversations, but also to any difficult and/or important conversations, personal or professional.
Misha Glouberman records a couple of consecutive coaching sessions with a volunteer (Tanya) who has an important and difficult conversation they need to have at work. After the coaching sessions, Tanya has the important conversation, and then returns to discuss with Misha how his coaching sessions helped shape the end result.
Added. Thanks!
I have a bunch that I like watching. I’ll add more in separate comments as I remember, but some highlights for transportation are Reg Local for driving cars (former police driving instructor; he has a book, but the videos themselves are so helpful) and Missionary Bushpilot for flying small aircraft in Papua New Guinea (gorgeous shots, very careful pilot).
Thanks, added! I look forward to seeing what else you have.
Domain: Farming Construction and Craftsmanship
Link: Simple off grid Cabin that anyone can build & afford: https://www.youtube.com/watch?v=bOOXmfkXpkM (and many other builds on his channel)
Person: Dave Whipple
Background: Construction contractor, DIY living off-grid in Alaska and Michigan.
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.
Thanks! Added.

Domain: Linguistics
Link: [The Art of Language Invention, Episode 25: Ghost Segments]
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 technical terms but his depth of knowledge is very obviously deep. In my own case, this video series, and the accompanying book of the same name were instrumental in my linguistics journey.
I did not know ‘conlangers’ were a thing. Thanks for sharing and added.
Domain: Technology
Link: [https://youtube.com/@primitivetechnology9550](Primitive technology)
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.”
Thanks for sharing! Added.
Domain: Math and Game Dev
Link: Shaders for Game Devs
Person: Freya Holmer
Why: She shares a lot of practical knowledge about math and shaders in her streams. She explains not just what, but why, answering people’s questions as she goes using her in-depth industry knowledge.
Thanks! Added.
Domain: VFX
Link: Vfx artists react to bad & great cgi
Person: Corridor Crew
Why: They’re skilled VFX artists reacting to good and bad VFX in movies. In doing so, they share tacit knowledge on compositing, lighting, 3D modelling, etc. They have lots of high profile guests from Seth Rogen to Adam Savage.
Thanks! Added.
Domain: Combat Sports
Link: Muay Thai Library
Person: Sylvie Von Duuglas-Ittu
Background: Muay Thai fighter with over 200 fights.
Why: Sylvie shows herself learning with her ‘Muay Thai Library’ videos. She narrates how she explores learning someone’s technique or strategy.
More than any particular technique, these videos show someone’s learning process. This is applicable to all combat sports.
Thanks! Added.
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:

For biology, JoVE (“Journal of Visual Experiments”) is a very good source of videos like this. https://www.jove.com/ Unfortunately it’s paywalled.
Domain: Language Learning
Link: YouTube Channel
Person: Alexander Arguelles
Background: Polyglot and director of foreign language education at various institutions, known in the community for his rigorous and inventive study methods
Why: He has various videos of him live-studying different languages which give learners direct insight into his methods.
The videos under this category fits better the label “game development” instead. Game Design is more focused on designing rules, mechanics, sometimes narratives, instead of programming.
Edited—thanks!
Beginner-friendly pottery tutorials and start-to-finish production explainers: Florian Gadsby on youtube. Notable in part for the high production values and clear explanations. The tutorials were particularly helpful for me earlier this year as I was just getting into pottery.
Domain: Software engineering, mech interp
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.

Link: GiveWell’s Public Board Meetings (2007–2020 have audio).
People: Elie Hassenfeld, Holden Karnofsky, Timothy Ogden, Rob Reich, Tom Rutledge, Brigid Slipka, Cari Tuna, Julia Wise, and others.
Backgrounds:
Holden Karnofsky. “Director of AI Strategy (formerly CEO) of Open Philanthropy and co-founder of GiveWell” (Website).
Elie Hassenfeld. co-founder and CEO of GiveWell (LinkedIn).
Timothy Ogden. Chief Knowledge Officer at Geneva Global, Inc.; founding editor of Gartner Press; founder of Sona Partners; chairman of GiveWell (Aspen Institute).

Brigid Sliplka. Director of Philanthropy at ACLU (LinkedIn).
Cari Tuna. President at Open Philanthropy and Good Ventures (Wikipedia).
Julia Wise. Community Liaison at Centre for Effective Altruism (LinkedIn).
Why: I’ve personally found it interesting to listen to these meetings for generally instantiating “what actually is a board meeting?”. They can be listened to just like you would listen to a podcast, in a multi-tasking sort of way.
