Lawn signs can influence how neighbors vote

UC DAVIS (US) — Neighbors’ lawn signs and public opinion polls can affect how people vote in an election, but it all depends on how far away the election is, research shows.

“Research like this highlights the fact that we are social creatures,” says Alison Ledgerwood, assistant professor of psychology at the University of California, Davis, and author of the study published in the journal Psychological Science.

“We clearly use other people to help us make our decisions, but what this research shows is that we rely on different people’s opinions for near-future and distant-future events,” she says.

Ledgerwood’s study—using both New York University and UC Davis student subjects in simulated votes and opinion surveys—found that when it comes to decisions about the distant future, peer group opinions carry a lot of weight.


“When thinking about an election that will occur next year, rather than tomorrow, or when voting by absentee ballot rather than in person at the voting booth, individuals may be especially likely to adopt whatever opinions seem to be endorsed by a majority of their group members,” Ledgerwood says.

But as an election nears, the views of individuals become more influential.

“Tuning into what the person sitting next to you happens to think about an issue is a great strategy for getting along in the current context,” she adds.

The research suggests that people making calls to voters months ahead of time trying to influence a vote might embrace specific tactics: “You might want to mention polling results. You might want to say: Most people in your political party think this is a good candidate or a good issue,” Ledgerwood notes.

However, polls announced the day or week before probably have little effect. “As we get closer to voting day, polls affect us less and less,” she says. “Meanwhile, what one other person happens to think might affect us more and more. The point is, we are always influenced by what other people think, but who influences us most is going to depend on timing.”
