A familiar debate in first-past-the-post democracies is whether ideologically disenfranchised voters should cast their vote for minor party candidates. We argue that voting for minor party candidates will sometimes be the best strategic option for voters with non-mainstream ideologies. Major parties, as rational agents, will be ideologically responsive to genuine threats of defection. By voting for a minor party, voters can simultaneously punish major parties for unfairly “bargaining” with their voting bloc and also signal their ideological reasons for defecting.

Predictive information is a popular and promising family of information-based theories of biological communication. It is difficult to adjudicate between predictive information-based theories and influence-based theories of biological communication because the same acts seem to count as communicative on both theories. In this paper, I argue that predictive information theories and influence-based theories give importantly different descriptions of deceptive signals in some non-evolutionarily stable communicative systems by citing a novel case observed in nature. Moreover, predictive information gives a counter-intuitive description (...) to the case while some of its rival influence-based theories do not. I argue that there are no clear ways for defenders of predictive information to respond to this apparent problem without sacrificing important virtues of their theory or deflating the difference between the rival views.
