4.3 Changes in Ideology
A political ideology is a consistent set of beliefs about what government should do. Your ideology can shift depending on when you were born and what stage of life you're in. Generational effects come from experiences shared by people of the same age, while life-cycle effects come from changes like starting a job, paying taxes or raising children.
Key terms
- political ideology
- generational effects
- life-cycle effects
What ideology is
A political ideology is a coherent set of beliefs about the proper role and scope of government. In the U.S., the main ideologies are liberal, conservative and libertarian (4.7). Many Americans don't hold a fully consistent ideology and call themselves moderates, combining views from different sides.
Ideology forms through political socialization (4.2). This topic is about two reasons ideology can change over time.
Generational effects
A generational effect (also called a cohort effect) happens when people who come of age at the same time share experiences that shape their political views, often for life. Events during adolescence and early adulthood seem to matter most, because that's when people are forming political identities.
Examples:
- Americans who came of age during the Great Depression and the New Deal of the 1930s tended to support an active federal government and the Democratic Party for decades.
- People who came of age during the Vietnam War and Watergate tended to be more skeptical of government.
- Younger generations today tend, on average, to be more accepting of same-sex marriage and more concerned about climate change than older generations were at the same age, reflecting the different world they grew up in.
Life-cycle effects
A life-cycle effect happens when people's priorities change as they move through stages of life, regardless of when they were born. Everyone goes through these stages, so the effect repeats in each generation.
Examples:
- Young adults who move often and are still in school are less likely to vote and may focus on issues like college costs and jobs.
- People who buy homes and pay more in taxes may pay closer attention to property taxes and the economy.
- Parents often focus on schools, safety and child care.
- Older Americans pay close attention to Social Security and Medicare and vote at the highest rates of any age group.
Telling them apart
Researchers often have trouble separating the two from one survey, since a 70-year-old today is both old (life cycle) and part of a generation shaped by particular events. Tracking groups over many years helps sort it out.
| Question to ask | Generational effect | Life-cycle effect |
|---|---|---|
| What causes the views? | Shared historical experiences of one age group | Life stage, such as age, career, family or retirement |
| Does it apply to all generations? | No, it's specific to the people who lived through an experience at a formative age | Yes, every generation passes through the same stages |
| Example clue | “People who grew up during…” | “As people get older…” or “Once people have children…” |
Worked examples
Try each one yourself first, then open the solution.
- Example 1
Generational or life-cycle?
A survey finds that people now in their 60s who were young adults during a severe recession still rate “economic security” as their top political priority, more than people their age did in earlier decades. Is this a generational effect or a life-cycle effect? Explain.
Show the solutionHide the solution
- Step 1: Ask what explains the pattern: a shared experience (a recession) when this group was young.
- Step 2: Check the comparison: they differ from people of the same age in earlier decades, so age alone can't explain it.
- Step 3: A pattern tied to one group's formative experience, not to age, is a generational effect.
Answer: A generational effect, because the shared experience of a recession in early adulthood, not age itself, shaped this group's priorities.
Common mistakes
- Labeling any age difference as generational. If the change comes from life stage, like having kids or retiring, it's a life-cycle effect.
- Assuming people's views never change after youth. Life-cycle shifts and major events can change them.
- Making sweeping claims about generations. Use “on average” or “tend to” language; individuals vary widely.
On the exam
- Multiple-choice questions often describe a group's views and ask whether a generational or life-cycle effect explains them. Look for whether the cause is a shared historical event or a life stage.
- Quantitative questions may show views by age group. Describe the pattern carefully before explaining it.
