The Institute kept advertising a worker study it never actually published.

Evidence

As a historical documentation of the situation and mentality of manual and white-collar workers on the eve of the Third Reich, and as a piece of pioneering empirical research in analytical social psychology, the study was certainly of great interest, and right into the 1940s the Institute repeatedly announced the projected publication of `Erich Fromm (ed.), The German Worker under the Weimar Republic’. — Rolf Wiggershaus, The Frankfurt School, 195

Categorization

• XREF: Connects to the Institute’s pattern of announcing then shelving empirical projects (the labor anti-Semitism study likewise never appeared).
