Explaining It Out Loud: The Research Behind Socratic Questioning and the Feynman Technique
If you can't explain it simply, you don't understand it. The Feynman Technique and Socratic questioning are backed by decades of research on the generation, self-explanation, and protégé effects — and, just as importantly, by sharp criticism of unguided discovery learning. Here's what the evidence actually supports and how Lambdio's Socratic and Feynman modes apply it.
The Testing Effect: Why Quizzing Yourself Beats Rereading (Even Though It Feels Worse)
Rereading feels more productive, but the research says otherwise. The testing effect explains why retrieving an answer from memory beats passive review, how big the effect really is, and why Lambdio's Quiz mode times it to the edge of forgetting.
The Forgetting Curve: Why You Forget Almost Everything You Study (and What Actually Slows It Down)
Ebbinghaus measured the forgetting curve over 130 years ago, and it still explains why cramming and rereading fail. Here's why memory decays, what actually bends the curve, and how spaced repetition scheduling models it today.
FSRS vs. SM-2: What the Research Actually Shows About Anki's New Algorithm
Anki's switch from SM-2 to the FSRS scheduler is the biggest spaced-repetition algorithm change in 30 years. Here's what FSRS actually does differently, what the benchmarks show, and what it means for your review time.
10% Better Exam Scores with AI Tutoring — What Our Pilot Study Found (and What It Didn't)
A pilot study with 30 university students found that active Lambdio users scored 10–15% higher on their economics final exam. We share the full data, methodology, and limitations.
