False feedback on choices has been documented to inducelasting preference change. Here we extend such effects to thepolitical domainand investigatethetemporal persistence ofinduced preferences, as well as, the possible role the length ofconfabulatory justifications may play. We conducted a two-day choice blindness experiment using political statements,with sessions being roughly one week apart. Changes inpolitical preferences remained one week after initialresponses, and were most prominent in participants who wereallowed to confabulate freely. These findings, being the firstto demonstrate lasting preference change using choiceblindness, are discussed in light of constructivist approachesto attitude formation through a process of self-perception.
