About Tankevarv
Tankevarv explains how things work, why people behave the way they do, and which ideas help us understand the world – one text at a time.
Short, concrete explanations of everyday technology and natural phenomena: zippers, refrigerators, GPS, batteries and much more. Each article answers one question, shows the key parts and explains the principle behind them.
Mental models, psychological effects, laws and principles from science and philosophy – from Goodhart's law to the Dunning–Kruger effect.
The texts are produced with the help of AI, but rest on research against named sources from universities, public agencies, museums and established encyclopedias. Every article is fact-checked separately and the sources are listed at the bottom. Found a mistake? Let us know.
