In winter 2025, Professor Phil Hammack was awarded a small grant from Division 1 of the American Psychological Association (the Society for General Psychology) to support the completion of his forthcoming book, “Radical Authenticity: The Twenty-First Century Revolution in Gender, Sexuality, and Relationships” (contracted with Oxford University Press’ trade division). The book blends a review of recent scientific research on sexuality and gender with an analysis of personal narrative interviews from the last decade of Hammack’s research in the Sexual and Gender Diversity Laboratory.
