Wow, James. You are *so* missing the point here.
Sure, there are evaluator effects in heuristic evaluations. But that
has to do with *different* evaluators inspecting the *same* design.
If I understand James correctly, he is suggesting that if the
evaluators knew which designers used personas then they would be
biased from judging objectively which designs were more user-centered.
That is, the so-called differences uncovered by the heuristic
evaluation might only be biases introduced by the evaluators.
If this is the case (and it's not clear from the writeup exactly what
was done), then the results of the study are biased.
Frank, could you shed some more light on this? Did the evaluators know
which designs were done using personas and which were not?
Cheers,
Josh
