Can you relate that to specifics from the article? To my (admittedly non-designer) eyes it appears to be a great example of how science can be used to improve design, and I happen to agree with the findings presented, so I'm curious where you see this breaking down.

The tacit assumption being made in the article is that good design shouldn't frustrate the users.

I don't disagree with this, but it's none the less an assumption that went into the study, and likewise a conclusion that fell out of it.

Nobody here is disputing we have values that are not scientific.
