Reification in knowledge representation is the process of turning a predicate[1] or statement[2] into an addressable object.
[3] The message "John is six feet tall" is an assertion involving truth that commits the speaker to its factuality, whereas the reified statement "Mary reports that John is six feet tall" defers such commitment to Mary.
In linguistics, reporting, telling, and saying are recognized as verbal processes that project a wording (or locution).
The reason for that is that statements are to be understood as an attempt to convince the addressee of something (Austin's How to do things with words), alternatively as a request to add some attribute to the model of Paul.
In other words, the issue of model inconsistency has to do with our model of the domain element (John) and not with the ascription of different range elements (measurements such as "five feet tall" or "six feet tall").
