I think 3x is the wrong target here, it's the learning by listening model aka "The Nurnberg Funnel" (or possibly Nuremberg Funnel for German speakers) that is harmful.

I'd rather have a more focused lecture at 1x speed, the same as I'd rather have a good textbook, but skimming in both cases is fine if you want some info but the presentation available is too simple for you.

But, learning by doing and finding out what you don't know by doing is important. That applies even to crappy end of chapter multiple choice quizzes or whatever their audiobook equivalent is, but I find project based learning to be where it's at for really cementing knowledge without boredom.

edit to add: I'm not sure about the bit about pre-textbook lectures is historically accurate. I was under the impression the modern lecture mostly derived from the time when books were expensive, non-mass produced tech and the single copy was chained to the lectern and the person reading it out was doing so in order to let people make their own cheap copies.

I'm a big fan of video lectures that people consume in their own time, but more because they can slow them down, and rewind, not because they can speed them up. If you're always speeding up, you could probably just get a denser text

I'm impressed more by the comments than the article itself. Some people insist they make progress and listen 3x, but nobody showed any practical measurements of own skills. A personal example: I used to listen to a famous linguist, and everything seemed nice and clear, but then I decided to go in details on one particular question (I think accentuantion), and opened his book. It was like if you showed your programmin…

I wonder the quality of learning if you listen to/watch something at 2x speed twice. Bonus if there is a delay in which your mind may formulate questions. I'm guessing it would be superior unless it was a very high difficulty piece. Having a basic understanding and then formulating questions allows you have an input on the learning, as opposed to simply listening. I would also say that with some material (esp. fictio…

I believe the research supports fast reading as being better, because you get more of an overview, but presumably this peaks at some point, same as audio.

clickbait.

this has nothing to do with the speed, it has to do with quality of information and implementation of it. there are people that never absorb anything or implement anything.

I can relate to Mike as well, I was one of those people that always had a side project hoping it would magically get big enough for me to quit my day job. No book helped with that, what did help was that I was at a company that ran out of money and eventually let my division off. I was raising capital on my lunch breaks and that was inefficient, so I realized that I actually didn't need to look for another job for once, and continued raising capital full time.

Capital made the next project big enough, and it was non-dilutive capital too, which skips any organic side project growth hopes.

So there should actually be more sympathy for the Mikes of the world. They are too comfortable, (or perhaps uncomfortable), to quit their job no matter what they learn.

You don't need a plugin to increase/decrease speed, the following bookmarklet works for most sites to increase speed by 10%:

javascript:(function(){ let speed =[...document.querySelectorAll('audio,video')].filter(v => v.currentTime > 0)[0].playbackRate += .10; console.log('media speed', speed); })()

In addition to what you're saying, it can also be _harder_ to watch something at 1x speed. I've found that at 1.25x-1.5x my mind is more engaged. If it's too slow, I start thinking about other things and end up getting less from the video.

To me this is fairly dependent on how fast the speaker speaks. Most of the times 1.25x works well. Sometimes 1.5x is too fast.

I find this true on podcasts; I'm normally a 1.3-1.5x person listening to podcasts, except "No Such Thing as a Fish". That one I go slower on, just because they seem to talk quite quickly, comparatively.

> Lectures are proved to be a bad way to learn things. This may be, but studies also show that you should review the material before the lecture so that you can engage the lecturer . I can count on a single hand and not use all the fingers the number of students I have taught who always reviewed the material before I lectured on it. Unsurprisingly, those students absolutely sailed through my class with very high grad…

I think for some subjects and some teachers, swapping homework time and lecture time can work. For example, if you are learning calculus, it may be more efficient for the teacher to assign reading a section of a textbook as homework and then in the classroom work through a bunch of problems and proofs using the homework material.

Same. Especially Youtube videos explaining and showing something really simple that takes like 5 seconds but they go on for 10-15 minutes. I suspect it has something to do with Youtubes algorithms that encourages creators to make long videos.

In part. There was definitely a 10 min target time for a long while. However, a lot of TV shows - particularly USA ones seem to needlessly repeat everything like there running a lecture for amnesiacs. Here's what we're going to say in the first part, here's the first part, we say what we said we would, now a recap, then a break so we review the whole first part ... now we're 10 minutes into the show and we've seen ab…

This lends credence to the educational reform that I always found the most compelling: kids/people should be reading the chapters for the lecture ahead of time as their homework, and doing the practice problems in class instead of a lecture, so the teacher can actually help students work through problems (rather than parents who don't know the material).

A brief review/lecture at the end to tie together all of that practice intoa coherent story then wraps it all up.
