Step-by-step explanation:
The two main assumptions of psychological theories in crime are determinism and genetic predisposition, and rational choice and free will. Determinism suggests that criminal behavior is determined by factors such as genetics or environmental influences, while genetic predisposition refers to the idea that some individuals may have a higher likelihood of engaging in criminal behavior due to their genetic makeup. Rational choice theory posits that individuals weigh the costs and benefits before engaging in criminal acts, while free will emphasizes that individuals have the agency to make choices about their actions.
