Abstract

Behavioral biology remains a field of inherent risk due to a persistent historical legacy of political and social distortion. Scientific frameworks such as polygenism, Social Darwinism, and eugenics were systematically employed throughout the nineteenth and twentieth centuries to provide a biological veneer for racism, slavery, and genocide. These movements frequently utilized flawed evidence regarding brain volume and “racial hygiene” to justify the suppression of marginalized groups. While the Boasian school later transitioned toward cultural relativism and emphasized universal mental functions, contemporary attempts to link race with cognitive ability demonstrate the continued appeal of biological determinism. Modern genomic data confirms the overwhelming genetic unity of the human species, illustrating that the vast majority of human variation exists within, rather than between, ethnic groups. Consequently, persistent disparities in social outcomes are more accurately explained by cultural and historical factors, such as systemic deprivation, than by genetic endowment. Despite a high potential for misuse, the study of the biological basis of behavior remains essential for a comprehensive self-understanding of the species, particularly in explaining the competitive and aggressive motives of oppressors. Researchers must, therefore, maintain constant vigilance against the recurrence of the shameful abuses that have historically characterized the application of biological ideas to social policy. – AI-generated abstract.
