A debate in psychology, linguistics, and other social sciences about whether human behavior (and for that matter, animal behavior and all other kinds of behavior) is determined by genetic or environmental factors. Or, a debate about what determines a very specific piece of behavior.

The debate is probably an ultimately fruitless one because it is impossible to operationalize either point of view, and thus both points of view are not even wrong. The interaction of genetics and environment is ridiculously complex from a very early stage; genetics determine, for instance, what sorts of chemicals are released into the womb during gestation - so do we call those chemicals innate factors or environmental factors? Eventually the entire argument reduces to semantics, in the worst sense of the word. Similarly, how one looks (arguably genetic) influences how one is treated (arguably environmental), which in turn influences a number of other factors, some of which eventually affect how you look.
