Step-by-step explanation:
The term collective sentiment refers to the overall public opinion or mood of a country at a given time. It encompasses the attitudes, beliefs, and emotions shared by a large group of individuals.
As revealed in James Stimson's study, collective sentiment can fluctuate and become more or less liberal over time. This changing sentiment has the potential to influence politicians' decisions on policy, although it does not imply a direct cause-and-effect relationship.
Public opinion is shaped by various factors, including the economy, social issues, and media influence. Understanding collective sentiment is crucial for policymakers and analysts to gauge the prevailing attitudes and preferences of the population.
