'Biological determinism' is the
hypothesis that biological factors such as an organism's individual genes (as opposed to social or environmental factors) completely determine how a
system behaves or changes over time.
Consider certain human behaviors, such as having a particular taste in
music, committing
murder, or writing
poetry. A biological determinist would look only at innate factors, such as
genetic makeup, in deciding whether or not a given person would exhibit these behaviors. They would ignore non-innate factors, such as social
customs and expectations,
education, and physical
environment.
Biologists sometimes regard a charge of biological determinsim as a
straw man, as there is currently no support for strict biological determinism in the field of
genetics or
development, and virtually no support among
geneticists for the strong thesis of biological determinism. However, individual scientists may disagree as to the role that genetic and environmental factors play. Modern genetics, in large part, is concerned with studying the dialogue between genes and environment.
Biological determinism is the opposite of
social determinism.
