Voting Not to Tell Others

People have been long known to overreport turnout. Most lies are misrepresented votes, i.e., people claim they did vote when they did not.
However, validation data shows that misreporting also happens the other way around: some individuals claim they did not vote, when in fact they did.
This paper uses validation data to find the reasons behind both kinds of misreporting. The focus is set on those who wrongly report an undesireable behavior.
That is, on those who claim to have abstained when in fact they had voted.
