As pointed out by Thaler and Sunstein in their excellent book
"Nudge," all interactions have an element of persuasion, whether
intentional or not. And, there are often social benefits to
designing for persuasion beyond the obvious business incentive (what
they refer to as "libertarian paternalism").
My impression of the HFI PET approach was that they needed to update
their old testing model which was based solely on "usability" best
practices that didn't really resonate with ecommerce clients. I
agree with many on this post that most of us have been doing this
along (how could we not?). HFI didn't "invent" it, they're just
reminding us that now they "get it."
