-Political advertisements on television are very frequent in election years. These political ads boost citizens' involvement, their interest in the election, and awareness of current issues. In recent years, candidates' advertising seems to focus on criticizing and discrediting their opponents rather than promoting their own ideas and solutions to problems. Is it possible that positive and negative advertising alters voter participation?

During a recent electoral cycle, investigators randomly assigned California voters to one of two groups. The voters in one group were shown a "positive" 30-second advertisement about candidates that were actually running for office. Another group of voters was shown a 30-second negative ad. After the ads were shown, the voters were asked about their voting intentions and general level of involvement in the campaign. Sixty-four percent of those who watched a positive ad intended to vote. Fifty-eight percent of those exposed to the negative versions of the campaign said they were likely to vote. The researchers concluded that the proportion of people who intend to vote was significantly lower for those who see a negative ad.
