Good info from Scott Young:

A great deal of psychological research shows that studying in a burst is less effective than study sessions spaced out over time. Blogs naturally embody the latter method, dripping out ideas over weeks and months instead of in a burst.

Bolding mine.

This aligns with what I was listening to on Tim Ferris’s podcast where he talks with Luis von Ahn where Luis says that users of Duolingo get best results with 20-30 minutes per day rather than bingeing.
