2 corrections applied: Thorndike's MGH cafeteria study was conducted 2010-2011 (published 2012, per the article's own reference), not 1987; she is a physician/internist, not a psychologist. | Lally et al. (2010) reported a mean (average) of 66 days to automaticity, not a median.
BeforeIn 1987, psychologist Anne Thorndike was running a study... actual data: 18 to 254 days, median 66.
AfterIn 2010, physician Anne Thorndike was running a study... actual data: 18 to 254 days, mean 66.
Why: Live article body already correctly said 2010/physician. Found the FAQ answer to 'How long does it actually take to form a habit?' still said 'with a median of 66 days' - fixed to 'with a mean of 66 days' to match the Lally et al. (2010) study's actual reported statistic, re-encoded via the 4-step base64/json op-sequence, and verified clean on re-fetch.
