Yet there are some opinions that 90% of the public, or close to it, shares — including a belief that citizens have a duty to vote, an admiration for those who get rich through hard work, a strong sense of patriotism and a belief that society should give everyone an equal opportunity to succeed. Pew Research’s political values surveys have shown that these attitudes have remained remarkably consistent over time. (Pew Research has been tracking political values for more than two decades; for the most recent political values survey in 2009, click here.)

The proportion saying they are very patriotic has varied by just four percentage points (between 87% to 91%) across 13 surveys conducted over 22 years. Similarly, in May 1987, 90% agreed with the statement: “Our society should do what is necessary to make sure everyone has an equal opportunity to succeed.” This percentage has remained at about 90% ever since (87% in the most recent political values survey).
