 Of course, if we are going to say that a causal model misrepresents the world, we must have a prior understanding of what the model represents. To misrepresent is to represent inaccurately. This section is going to be focused on the question of what it is for a causal model to represent accurately. There is of course a further and subsequent question to be asked about when the inaccuracies of the model are negligible enough that the model may be appropriate or apt to use in a given context.
