   2 corrections applied: Festinger's 1954 paper was published in Human Relations, not Psychological Review. | Brewer's 1991 optimal distinctiveness paper appeared in Personality and Social Psychology Bulletin, not the Journal of Social Issues.

   Before

   Leon Festinger had established in 1954, in Psychological Review, that people evaluate their opinions... published a highly influential paper in 1991 in the Journal of Social Issues... Brewer, M. B. (1991). The social self: On being the same and different at the same time. Journal of Social Issues, 47(2), 475-482.

   After

   Leon Festinger had established in 1954, in Human Relations, that people evaluate their opinions... published a highly influential paper in 1991 in Personality and Social Psychology Bulletin... Brewer, M. B. (1991). The social self: On being the same and different at the same time. Personality and Social Psychology Bulletin, 47(2), 475-482.

   Why: Body text already correctly cited both journals (Human Relations for Festinger 1954, Personality and Social Psychology Bulletin for Brewer 1991). However, the bibliography/references list entry for Brewer (1991) still had the stale incorrect journal name 'Journal of Social Issues'.

   Corrected the bibliography entry to 'Personality and Social Psychology Bulletin' to match the body text and the actual published source, PUT to the live post, and verified via re-fetch that the fix landed cleanly with no other fields affected. FAQ field checked (decoded via base64/json/base64/json) - no mention of Festinger or Brewer in the FAQ, so no FAQ fix was needed.
