===== ✅ What you can do to track it down =====
* Look up all the bibliographic footnotes or end-notes in the section of “Map of Consciousness” where Hawkins mentions it. See if he gives a study name, authors, or year.
* Search databases (PubMed, PsycINFO, Google Scholar) using keywords like: “premenstrual tension”, “expectancy”, “saline injection”, “hormone injection”, “placebo”, “menstrual cycle experiment”.
* Search older female-hormone/menstrual cycle literature from the 1950s-1970s: PMS was first widely discussed in those decades (Dalton’s work for example).
* Check books on PMS history (especially those discussing psychological/sociological aspects, not just hormonal). E.g., see the PDF of “A Sociological Analysis of Premenstrual Syndrome”.

* If you have access to a university library, ask a librarian for older journals (e.g., Psychosomatic Medicine, Journal of Psychosomatic Research, British Journal of Obstetrics & Gynaecology).
* Possibly reach out to Hawkins’ sources: if he lists a bibliography, you might locate the original article via interlibrary loan.

If you like, I can attempt a deeper archival search (going back to older literature, non-digital journals, etc.) to find that specific experiment you referenced (the “70% developed early PMS” one) and see if a full citation exists (author, journal, year). Would you like me to proceed with that?
