Dear Terry,
No! I think you're mistaken here. Jurgen, in his opening
post, of December 17, 2012, wrote:
"I was looking into the possibility to find some articles
about 'testing of design theory' and I haven't found too
many articles. ..."
My reply too talked plainly of testing a theory of designing,
and the paper I attached is about testing to see if work on a
theory of designing was "on the right track," not about
testing its validity. So, I think it's clear that neither of
us just asked about testing the validity of a theory.
The discussion from the start has been wider than just how to
test validity. Look at what Keith, Jurgen, Charles, and Ken
have all subsequently posted. It's you who have narrowed the
discussion to validity testing, not me, not Jurgen, and not
others.
And, if I may add, it's you who have diverted the discussion
into a dark corner by throwing in Popper's tiny worlds notions
... Oops, sorry! I mean Sir Popper's "Thee Incommensurate
Worlds" view.
Plonking this into the middle of the ongoing discussion with
no attempt to explain why and how you think this helps at all,
has simply diverted the discussion, not progressed what was
already on going. You don't tell us how Popper's views
usefully address issues already raised, or how they identify
and usefully resolves important issues others have failed to
acknowledge in the ongoing discussion.
You have taken us into this dark out of the way corner where
I, for one, see no useful enlightenment. It's therefore up to
you to put some light on the matter. So, please, show us,
with citations to published work, how you have found Popper's
Three Incommensurate Worlds view to be useful in testing some
theory of designing. Just asserting that you have found it
useful does nothing for the discussion. And please note, I
say theory of designing, not any kind of theory. So, let's
keep the discussion relevant to the topic, please.
Best regards,
Tim
