Benjamin Bloom

Who they are

American educational psychologist (1913–1999) best known for Bloom's Taxonomy (1956) — the hierarchy of learning objectives from recall through creation — and for the 2 Sigma Problem (1984), his finding that one-on-one tutoring lifts students two standard deviations above classroom-taught peers. Bloom's 2-sigma paper is now the foundational citation for every AI-tutor startup on earth, which makes him unexpectedly relevant to 2020s tech strategy.
