Women's Brains, Male Specialists — The 2000 fMRI Myth

A new study claims women are not inherently better at multitasking than men. This finding arrives decades too late to kill the myth it debunks.

The claim became gospel in corporate training, academic pop-psychology. The default assumption of anyone hired to manage a fragmented knowledge worker in the last twenty years. The finding is being treated as a fresh discovery. It's an autopsy of something that should never have been alive.

The story begins in 2000, when neuroimaging was new enough to feel revelatory and old enough to seem rigorous. Researchers at Florida International University ran fMRI scans and observed that women's brains appeared to activate both hemispheres during language tasks while men's activated only the left.

The finding spread through a particular ecosystem. Science journalists reported it, corporate training consultants weaponized it, and HR departments cited it. By 2005, the claim had calcified into common knowledge. Women's bilateral language processing made them natural multitaskers. The inference was never tested against actual multitasking performance in any rigorous way because it didn't need to be. The belief was useful to employers precisely because knowledge work was exploding into email, Slack, meeting culture, and constant context-switching.

This mirrors how the D. A. R. E. program persisted for decades despite evidence it didn't reduce drug use. The program was organically useful to institutions that needed visible prevention theater, not prevention that worked.
