Adorno argued modern individuals have no psychology separate from society

Evidence

In Adorno’s view, modern man was no longer even capable of `spontaneous’ anti-Semitism, as he put it, and no longer represented a suitable object of study for genuine psychology: the psychologist examining him must inevitably become a sociologist, since he was directly encountering society within the supposed individual. — Rolf Wiggershaus, The Frankfurt School, 447

Categorization

• DEEPTHINKING: Dissolves the psychologist/sociologist boundary by claiming the individual’s interior is directly society — a paradigm claim, not a disciplinary quibble.
• XREF: Resonates with the Frankfurt School’s ‘end of the individual’ thesis and with the culture-industry chapters on the decay of inner life.
