Elderly Suicide from an Evolutionary Psychology Perspective

Elderly suicide is a pressing public health issue characterized by notably high rates in many countries, including China. From an evolutionary psychology perspective, suicide represents a paradoxical, counter-evolutionary behavior that appears to reduce an individuals inclusive fitnessthe ability to pass on genes directly or indirectly through kin. This study investigates elderly suicide through the lens of inclusive fitness model, which suggests that under conditions of resource scarcity, older adults may opt for suicide as an adaptive mechanism to alleviate burdens on their kin while also promoting the wellbeing and future reproductive potential of younger relatives.The study hypothesizes that elderly individuals who perceive themselves as financial or emotional burdens to their families develop feelings of hopelessness and depression. Depression initially promotes rumination and social signaling aimed at eliciting support; however, when these efforts fail, cognitive confusion and impulsivity may emerge, weakening natural survival instincts and increasing suicide risk. We plan to conduct the study in several steps to illustrate the inclusive fitness model, and we will discuss the expected outcomes and implications. The plan of study could highlight adaptive mismatch, where evolutionary mechanisms misfire in modern social environments, stressing the need to address financial and emotional burdens through programs that enhance emotional connectivity, social roles, and community support to reduce elderly suicide risk. However, the plan also has limitations including self-reported data bias, sampling issues, and challenges applying evolutionary models across cultures, with future research urged to develop cross-cultural, multilevel interventions targeting psychological, family, and societal support.
