The most important statements of each year; all statements.

2020

  • 2020-02-13 · Top 5 Revision & Study Tips for Students — Ali explains that in the 1800s Ebbinghaus found memory of anything learned decays exponentially, and that revising a topic the next day, then a week later, makes it take longer to forget each time. — 00:00:58
  • 2020-02-28 · My Favourite Note-Taking App for Students - Notion — Ali: Spaced repetition counteracts the forgetting curve, which Ali says Ebbinghaus discovered in the 1800s: memory of anything learned decays exponentially over time. — 00:12:05
    • Forgetting a topic a week later does not mean you are stupid, Ali says: your friends have the same problem, since forgetting what you do not revisit is an innate part of how memory works. — 00:12:05
    • Ali's spaced repetition: do a topic on day one, again the next day, a week later and a month later; each repetition interrupts the forgetting curve and makes forgetting slower, until the topic is in long-term memory. — 00:12:42
  • 2020-03-13 · The KEY Study Techniques for Exam Success — Ali: With the peg system Ali memorised a list of about 50 references the night before a second-year exam, and forgot them the next day because he had not repeated them. — 00:28:37
  • 2020-08-11 · Study with Me - Hustle & Chill — Ali's delayed active recall tests him on material from a few weeks ago, using the spaced repetition effect to combat the forgetting curve. — 00:02:20
  • 2020-10-08 · How I Remember Everything I Read — Ali cites the forgetting curve of memory research: over time memory for everything decays unless we find a way to engage with it. — 00:00:58
  • 2020-11-15 · How I Gained 1 MILLION Subscribers — Ali: Laying the forgetting curve over the growth graph, Ali says that about 302 videos in he has forgotten how much effort the early work took; two or three videos a week now feels normal. (hedged) — 00:02:27

2018

  • 2018-04-09 · How to Study for Exams - Spaced Repetition · Evidence-based revision tips — Ali says spaced repetition works because of the forgetting curve, known in psychology since the 1800s: over time we forget things at an exponential rate. — 00:01:36
    • Ali says each review interrupts the forgetting curve, and after each interruption it takes longer to forget the material. — 00:02:05
  • 2018-12-22 · Study Tips - How to learn new content — Ali describes the forgetting curve: over time you forget everything you have learned unless you revisit it by testing yourself. — 00:09:30
    • For spaced repetition, Ali advises testing yourself the next day, again after a week and again a month later; after three or four repetitions over a month or two the forgetting curve is very flat. (hedged) — 00:09:59
