Chapter Introduction:

Public opinion isn’t just a number in a poll—it’s a reflection of our life experiences, values, and what we’ve picked up from family, school, media, and society. This chapter explores how our beliefs are shaped over time, how pollsters try (and sometimes fail) to measure them, and why public opinion matters in politics. From campaign strategy to court decisions, what the public thinks can influence elections, policymaking, and even the balance of power—though not always in predictable ways. Get ready to see how everyday attitudes can steer big decisions.
