  text: In evolutionary game theory interactions between individuals are often assumed
    obligatory. However, in many real-life situations, individuals can decide to opt
    out of an interaction depending on the information they have about the opponent.
    We consider a simple evolutionary game theoretic model to study such a scenario,
    where at each encounter between two individuals the type of the opponent (cooperator/defector)
    is known with some probability, and where each individual either accepts or opts
    out of the interaction. If the type of the opponent is unknown, a trustful individual
    accepts the interaction, whereas a suspicious individual opts out of the interaction.
    If either of the two individuals opt out both individuals remain without an interaction.
    We show that in the prisoners dilemma optional interactions along with suspicious
    behaviour facilitates the emergence of trustful cooperation.
