What "I Voted" Stickers Actually Do

On Bill Maher's latest show, while lamenting that more people in our society don't vote, he lampooned the idea of the "I voted" sticker as bragging about performing a relatively minor civic duty. I see it differently. When you wear an "I voted" sticker in a culture with low voter turnout, the sticker serves as a reminder to others that it's election day. The stickers also have some potential to create social or peer pressure to vote.
