Building upon the two-tiered model of life history strategies introduced by Ellis, Reid, and Kramer (2024), we discuss avenues for future research that apply the theory to sexual and gender minority individuals. We propose that minority stress and suicide exposure may serve as extrinsic ambient mortality cues among sexual and gender minority (SGM) populations. We also identify a feature of pubertal development requiring more consideration.
