About
A friendly tour through the school facts that science quietly corrected after you stopped studying for the test.
What is this?
Disproven Facts shows you the school lessons that have aged - ideas your teachers stated as settled science and that the scientific record has since updated. Pick the year you graduated and you get the corrections most relevant to your era.
How facts are selected
We focus on North American K-12 curricula from 1945 to today, drawing on changes in published textbooks, standards documents, and the underlying research. We don’t include every interesting science update - only ones that mainstream schools were actively teaching at some point.
Coverage
