Rational Action and Evaluation

People generally act for reasons (in this context at least), and are expected to be able to give reasons for their action. This is the same for communication transactions, in that communicators are expected to give valid truth-claims as statements and to provide reasonable explanations for why they hold those claims to be true. If a software developer claims her software provides a certain feature, she must have a reason for making that claim, and a user going to use the software and not finding the feature would have good reason to doubt the motivation of the developer. This sort of breach of the norms discussed above would disrupt the communication transaction and thus break an informed consent process. The rational evaluation users make of interactions with the developer affects the relationship and communication with the developer.
