You're touching on a big important difference between Austrians and the mainstream that is also a point of commonality.

Mainstream economists give the impression of extreme confidence in their tools, while Austrians are openly critical of those tools.

The truth, as you say, is that most economists are at least intellectually aware of the deficiencies in our tool kit.

I think this helps Austrians to not get seduced by the fancy methodologies, but it also makes it very difficult to communicate across the divide.
