Is anyone aware of a commercialized app that enables team learning through spaced reputation? Say for a support team learning a new process or skill where the learning can be heavily curated? Thanks in advance.

What bit do you doubt? The core concept that spaced repetition increases rapidly in effectiveness over time is called the Spacing Effect. There are many many studies that have investigated and proved it
> It takes you years to get twice as effective at reading Evidence? What's the evidence this is a linear growth process? How many years? At what age? What populations? There is no rigor here at all.
Then it says for the "best case" that "adults" takes years to get twice as effective at reading.
If you don't believe this then it means you think it takes adults less than a year to get twice as effective? If effectiveness doubles each year then that would mean by the time a 25 year old becomes 65 that they're 1 million times as effective at reading than when they were 25. Does that sound reasonable to you?

Haha, where would you rank this one in terms of quality?
To be perfectly honest, I flagged it because of the knowledge gained graph. It's a wild extrapolation. For context, I was a big fan of SRS and even contributed to Anki back in the day! I was really into foreign language learning, had majored in one language and was learning another language in a separate language family. I built, ran and put my heart into brick and mortar language immersion school for years. Over tim…
Effectiveness of spaced repetition scales really fast / exponentially whereas other learning methods don't scale like that - do you agree?
If so then over the long-run spaced repetition is always going to be extremely efficient relative to other learning methods.
Title is misleading. This isn't learning exponentially. Anybody who has used a spaced repetition app (like Anki) knows that you generally learn around the same number of words every day. You're not going to be learning 10 words in a day and then one week later, learn 1000 words in a day. This article talks about how the reps needed to learn one piece of information, reduces exponentially over time. You might need 1 r…
Think about it in terms of how many days of knowledge each rep gets you. The first rep gets you 1 extra day of knowledge. The next rep gets you 2 extra days. The next one gets you 5 extra days. So each rep is getting you more and more knowledge even though the time required to execute the rep remains the same. This is exponential growth. If you only have 1 card then for most days you won't have any reviews to do so i…
Another method I have used in the past is to rewatch content I used to learn a subject at 3-4x speed. A lot of high quality content that spans multiple days can be viewed in only a few hours this way. The key I’ve learned with this is to do this across variations of the content you wish to learn and re-learn. Combine this with audio books at similar speeds and you can really get through content very quickly. When usi…
How do you get videos to 3-4x speed? I find most video players only allow up to 2x speed?
Spaced repetition turns reading into a physical activity with feedback. If you had an activity that required the knowledge you were hoping to acquire, you would learn at the same rate or faster by practice. Most lessons are encoded really poorly. I think spaced repetition is great, but practice at something is better. A hacker is just someone who has practiced learning independently and has become exceptionally good…
Reading this comment had me cheering “yes, a thousand times yes” but then it occurred to me how often I turn to an O’Reilly book instead of a concrete project and I wondered why. I think I subconsciously avoid new projects to learn something programming-related because of how often they end up unbounded in time due to one of the fundamental attributes of writing software: unknown unknowns. The kinds of sticking point…
If I want to do something like move a light fixture in my house, it seems like it should be fairly straightforward. Choose where I want the new one to be. Create hole. Move wires. Connect fixture.
But it only seems that simple because I'm ignorant. I have to install a new junction box, which requires having a joist nearby, or adding a cross-support between two. Am I going to need to move any insulation? What insulation do I even have? Is the existing wiring long enough, or in the right place, or am I going to have to replace it? And I need to pin the wires down every so often? What? How? Where? Where do I even find that info? And never mind patching the hole I'm leaving behind. It's not just eyeballing a drywall patch. I can't match the old texture of the ceiling, even if I thought it was plain. My patch is really noticeable. And on and on.
Unknown unknowns take what I thought was going to be a little afternoon project and turn it into asking all my friends for recommendations of people who aren't booked 6 months out and are willing to handle a tiny little project cleaning up after my ignorance.
Taking on projects before I even know what I don't know has gotten me into more trouble than just about anything else.
I've never nearly burnt my house down taking notes from a book and hiring a professional to do the actual work!
I apologize in advance to the author but this is pretty dumb. Learning is not remembering all the words in a dictionary or all entries in an encyclopedia. You learn exponentially by layering concepts and ideas, one more complex than the previous one, on top of each other. You advance by understanding more deeply what you read and actually think for yourself. Wise men recommend to learn for 1/3 of the time, think for…
You misunderstand how important memory is for learning. Ofsted, the UK school inspection board, actually defines learning itself as a "change in long-term memory". You can't learn anything without a change to your memory, they aren't separate things. So, sure, you should try to apply your knowledge and layer concepts on top of each other. But if you do that AND also remember a lot more of such experiences you'll lear…

Limit the degrees of freedom. If the goal is to learn a new programming language, pick an interesting problem that you’ve already solved (e.g. todo list manager, pomodoro timer, etc.). If you want to learn a new domain (e.g. networking), pick a familiar language. Choose boring tech for everything else—-things like deployment, monitoring, etc. If your goal is not learning k8s, just SCP stuff to a VPS. It can be crappy…

I agree that memory is (very) important for understanding but not in the way it’s purported by the article. I don’t need to remember the exact way something was written by the author. In fact, I’d argue that by focusing on literal remembering you are understanding less than otherwise.
I agree. Who ever said you should try to remember that? Remember the high-level important and transferable information, don't waste time trying to remember information that won't help you elsewhere.
