Definitions:

Instinctive Drift

The tendency of learned behavior to gradually revert to biologically predisposed patterns.

Biologically Predisposed

Being biologically predisposed means having an increased likelihood of developing certain characteristics, behaviors, or diseases due to genetic factors.

Learned Habits

Behaviors acquired through repetition and reinforcement, becoming automatic responses to specific situations.

Biological Constraints

Biological constraints are limitations on learning that are caused by the biology of the organism, suggesting that some behaviors are inherently more difficult to learn than others due to genetics.
