 Conditional preferences allow modelling doxastic preference change. What matters for an agent’s evaluation and behaviour are his unconditional preferences, \(\succcurlyeq_t\), which are unconditional only in the sense that they rely on the agent’s actual information at time \(t\). When the agent accepts a new proposition \(A\) at time \(t+1\), his conditional-on-\(A\) preferences become his unconditional preferences at \(t+1\): \(\succcurlyeq_{t+1} = \succcurlyeq_{A}.\)
