 But, just as changes in the agent’s information (knowledge, beliefs) should trigger changes in her intentions, changes in her intentions may also trigger changes in (some of) her beliefs. Intuitively, having the intention to achieve a given \(\varphi\) reduces the actions that the agent ‘can’ perform, from the ones she can actually carry on, to those that will still allow (and maybe assure) that \(\varphi\) will be achieved. In other words, a change in the agent’s intentions triggers also a change in her beliefs about the (sequence of) actions that will be available in the future. This is the idea followed in Icard, Pacuit, and Shoham (2010), which studies the interaction between intention revision and belief revision by introducing postulates for both actions, with these postulates describing the two processes’ interplay. In the interesting case of intention revision, the postulates state that (i) a new intention will take precedence over previous ones (and thus old ones should be eliminated when in conflict), (ii) modulo coherence, no further change should be made on the agent’s intentions (in particular, no extraneous intentions should be added), and (iii) non-contingent beliefs do not change with intention  revision.[16]
