Jeffrey,
Interesting. I once used the same approach to try to "define" design itself
- by looking at what design was not.
I think a key feature of evidence in design is whether it leads to
predictive conclusions. That is, given some evidence about a design and its
situation, one reasons to a conclusion that makes a prediction about the
design - that it will have the desired impact when implemented - that is
borne out in reality when the design is actually implemented.
