Contexto
What changed: Undergraduate students were sent an email offering entry into a lottery with five $300 prizes conditional on voting in an online student government election. Comparison: Students who received an identical encouragement email without the lottery offer. Limits: Setting was a low-salience online student election at a single US public university, which may not generalize to high-salience public elections or in-person balloting.
