 The proposal of Boddy (2014) and Baltag, Boddy, and Smets (2018) studies these concerns (then also studying what the ‘real’ common and distributed knowledge of a group is). Their model (based on the epistemic issue model introduced in van Benthem &amp; Minica 2012) assumes that agents have not only their individual knowledge, but also their individual issues: the topics that each one of them has put on the table, which determine their individual agenda on what is currently under investigation. On the syntactic side, besides the standard knowledge modality \((K_i\) for each agent i), there is also a modality \(Q_{i}\varphi\), read as “\(\varphi\) can be known solely based on learnable answers to i’s questions”. In other words, \(Q_a\) describes the maximum knowledge agent a can acquire, given her questions and the answers that are learnable for her. Thus, as a principle, if a knows \(\varphi\), she can know it solely based on answers to her question(s):
