Last week i read a few articles about scientific studies that seem to show that

- people forget everything they learn in school, unless they already know it from general osmosis
- people also forget everything they learn in university, but it doesn't matter because people don't go there to learn but to get a degree
- scientists (especially sociologists) do not understand statistics, not even statisticians
- the likelihood of a paper passing peer review is only lightly correlated to the quality of the paper

I guess the first thing explains why it seems to matter so little (after a decade) whether you send a kid to a regular school or do something like homeschooling or montessori. Although it's hard to say if this applies to all kinds of schooling or just to the current degree-based system.
