Yes, of course. That's the reason why the identity model exists in the first place. It is quick and easy to make a decision using it, and it often gives the correct answer, or nearly so. Nice and simple heuristics like this one are very useful in our day to day lives. However, to the extent that it differs from the consequences model, it is wrong. As such, we should do our best to minimize our reliance on it.

Or put it this way: The phrase "heuristics and biases" exists, and paints out a natural part of conceptspace. In the same way that we want to reduce biases in our thinking (to the extent that it is possible to do so, of course), we want to reduce the use of heuristics in our thinking. (Again, to the extent that it is possible to do so, of course.)
