I strongly oppose vote-by-mail and vote-by-phone, but for a different and underappreciated reason: the secret ballot is absolutely essential for escaping from preference falsification traps.<p>"Preference falsification" is a social phenomenon in which, between choices A and B, most people prefer thing A but believe that everyone else prefers B, making it socially unacceptable to express support for A. If votes are public, then everyone feels compelled, upon threat of ostracism, to vote for B, leading to enactment of policy that's actually extremely unpopular. Under a secret ballot system, people can profess support for B while secretly voting for A, and if everyone does so, policy A ends up being enacted, concordant with the true preferences of the population.<p>If you can vote by mail, or vote by smartphone, nothing stops people from supervising each other's votes. That there's currently a norm against doing in vote-by-mail jurisdictions is purely a cultural holdover from the days of the true secret ballot, and it's only a matter of time before this norm erodes.<p>We live in an age of moral panic and socially enforcement of beliefs that are both unpopular and, in many cases, scientifically incorrect. Let's not make the problem worse by making it even harder to escape from the preference falsification trap.
