7.1 Formation and measurement of public opinion

Public opinion formation is a complex process shaped by various factors. Socialization agents like family and media, along with demographics such as age and race, play crucial roles in shaping individual and collective views on important issues.

Measuring public opinion involves diverse techniques, from traditional surveys to advanced digital methods. While each approach has strengths, like random sampling in polls, they also face limitations such as potential bias in online surveys. Understanding these tools is key to grasping public sentiment.
