Do you agree with the assumptions of the Anki scheduler? That each time you review a card you'll remember it for incrementally longer and longer? If so then a fixed amount of review time per day will let you remember things for longer

thanks a lot, your comments make a lot of sense and are really helpful!

Do you agree with just this part? > Effectiveness of spaced repetition scales exponentially

by p-christ 4y ago
If you've forgotten something then you don't have that knowledge anymore. So remembering things for longer means you are effectively gaining knowledge. It's like someone giving you $10 and then trying to argue that they haven

> I don’t need to remember the exact way something was written by the author. 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 remembe

The simplifying assumption around units of information and the graphs are just to visualise the main point. Effectiveness of spaced repetition scales really fast / exponentially whereas other learning methods don't scale like that

The article links to a paper which estimates how much more effective you get at reading the more knowledge you have. It shows that for most ages you don't improve in this way, but for older ages you do. Then it says for the "best

Save All does that. You can create a deck and then share it so a whole team can use it https://saveall.ai/

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, the

Thanks for the feedback, we are going to add an export feature sometime soon

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 knowl

Summary of article: The effectiveness of spaced repetition scales exponentially and much faster than other learning methods. So use spaced repetition and you’ll learn a lot faster in the long-run.

I use it for both types yeah. I basically try not to ever forget anything I hear that’s useful. On Save All you can create cards that are just statements, no need to turn them into Q&A. So if I hear an interesting fact I usually just du

Haha, where would you rank this one in terms of quality?

by p-christ 4y ago
Agree, I shouldn't have used the word "proved". But there is a lot of robust evidence for it going back to the 1800s. Many of the studies are linked to on the wikipedia page https://en.wikipedia.org/wiki/

by p-christ 4y ago
Yeah. There is software that organises the reminders for you aswell e.g. my company Save All does this https://saveall.ai/

Very interesting, how would i learn about something like that? Is there a resource you'd recommend?

by p-christ 4y ago
thanks will check that out

by p-christ 4y ago
what's that?

by p-christ 4y ago
thanks lol

This seems like what a spaced repetition app does, is there a difference? For example lots of people use Save All for this exact reason https://saveall.ai/

> It only takes days to get twice as effective at reading with spaced repetition? Or at learning? If it's the latter, I don't think that's what the earlier study measured? It only takes days for spaced repetition to get t

How do you get videos to 3-4x speed? I find most video players only allow up to 2x speed?

by p-christ 4y ago
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

by p-christ 4y ago
For sure it's also good to practice things aswell, it doesn't have to be only one or the other. My understanding and experience is that if you do 95% practice & 5% spaced repetition you will be significantly better over the lo

Sorry, you're right. I was maybe too focused on being efficient rather than polite. I'll edit my comment

I understand what you mean but I think you underestimate how critical memory is for all forms of learning (even creative work/learning). Our working memories have a capacity of 4. This means that we basically can't understand some

So there is a theroetical point at which your brain will get "full" but it would take so much knowledge to do that that it's basically impossible.
