Final answer:
Consumer self-regulation is the term that describes a buyer's effort to resist external influences on shopping choices, focusing on personal choice and freedom while managing cognitive dissonance and avoiding conformity.
Step-by-step explanation:
The term that refers to a buyer's inclination to obstruct external or circumstantial influences from interfering with shopping choices is Consumer self-regulation. This concept is related to the broader fields of behavioral economics and consumer psychology, where individuals actively resist external pressures and attempt to make purchasing decisions based on personal values and self-set rules.
It is a part of how consumers maintain their autonomy and personal freedom in the face of marketing campaigns, social norms, and other external influences. Personal choice and freedom are central to consumer self-regulation, as buyers pursue their own interests and resist conformity to external pressures, thereby exercising control over their consumer behaviors. Issues such as cognitive dissonance and conformity also play roles in how individuals regulate their purchasing behaviors, aiming to maintain consistency with their beliefs and values.
