Final answer:
People from the same culture can predict one another's behavior because of shared cultural norms, values, and practices. Culture influences behaviors and shapes attitudes and beliefs. Familiarity with cultural customs and social expectations enables people to anticipate how others will likely behave.
Step-by-step explanation:
People from the same culture can predict one another's behavior because of shared cultural norms, values, and practices. Culture influences individuals' behaviors and shapes their attitudes and beliefs. For example, in collectivistic cultures, people prioritize the well-being of the group over individual needs, leading to behaviors that benefit the entire group.
Additionally, individuals are attracted to others who share similar cultural backgrounds, which further reinforces the predictability of behavior within a culture. Familiarity with cultural customs and social expectations enables people to anticipate how others will likely behave in certain situations.
However, it is important to note that while culture provides a framework for predicting behavior, individuals within a culture still possess unique characteristics that may influence their actions differently.
