• Identify factors that change public opinion
• Compare levels of public support for the branches of government

While attitudes and beliefs are slow to change, ideology can be influenced by events. A student might leave college with a liberal ideology but become more conservative as she ages. A first-year teacher may view unions with suspicion based on second-hand information but change his mind after reading newsletters and attending union meetings. These shifts may change the way citizens vote and the answers they give in polls. For this reason, political scientists often study when and why such changes in ideology happen, and how they influence our opinions about government and politicians.

Experiences that affect public opinion

Ideological shifts are more likely to occur if a voter’s ideology is only weakly supported by his or her beliefs. Citizens can also hold beliefs or opinions that are contrary or conflicting, especially if their knowledge of an issue or candidate is limited. And having limited information makes it easier for them to abandon an opinion. Finally, citizens’ opinions will change as they grow older and separate from family.

Citizens use two methods to form an opinion about an issue or candidate. The first is to rely on heuristics    , shortcuts or rules of thumb (cues) for decision making. Political party membership is one of the most common heuristics in voting. Many voters join a political party whose platform aligns most closely with their political beliefs, and voting for a candidate from that party simply makes sense. A Republican candidate will likely espouse conservative beliefs, such as smaller government and lower taxes, that are often more appealing to a Republican voter. Studies have shown that up to half of voters make decisions using their political party identification, or party ID, especially in races where information about candidates is scarce.

In non-partisan and some local elections, where candidates are not permitted to list their party identifications, voters may have to rely on a candidate’s background or job description to form a quick opinion of a candidate’s suitability. A candidate for judge may list “criminal prosecutor” as current employment, leaving the voter to determine whether a prosecutor would make a good judge.

The second method is to do research, learning background information before making a decision. Candidates, parties, and campaigns put out a large array of information to sway potential voters, and the media provide wide coverage, all of which is readily available online and elsewhere. But many voters are unwilling to spend the necessary time to research and instead vote with incomplete information.
