Hi Nelson,
Thank you for your message. At root, it appears to me this is a matter of _choosing_ definitions because we are using the terms technically in building design theory. It is also a particular case where reference to dictionary definitions and the etymology of 'judgement' and 'decision-making' doesn't help much. In my experience, dictionaries define these terms pretty well identically and there are two strong pretty well equivalent etymological pathways in Latin: 'judex' ('ius' - right + 'dic' from dicere (to speak)) and 'decidere' (to cut down/away).
There is so much overlap in the dictionary definitions on these terms, that I suspect we are going to make more of a conceptual and terminological mess if we try to define major differences between the terms to use them technically in theories in design research.
In addition, there is the significant reality that these terms and concepts originated before the current possibilities to look inside humans to see what is going on biologically. I know I keep harping on on this but epistemologically this is really significant. This ability to look inside humans to understand the real physical processes by which we do things such as 'decide', 'intuit' , 'think a new thought' or 'feel' is very recent but already very illuminating and reliable. In previous times, without this ability to look inside at the reality of human functioning, it has been necessary to make all sorts of place holder ideas such as 'knowledge' and 'mind', and to develop theories that in a third hand way to discuss internal human issues in terms of things outside humans (e.g. behaviours, objects, social relationships etc). Times are a changing and these old ways of theorising are becoming redundant. From this point of view, as far as I can see, its better to look to the new if one wants to make good design theory.
Warmest wishes,
Terry

There is a related idea concerning judgment that Horst Rittel proposed.
Since any rational decision-making process increases options rather
than reduces options, Horst said that every decision-making process was
terminated by an "off hand judgment" leaving one option for further
consideration. In other words it leads to an opinion or 'expert
opinion'. This is demonstrated by the many conflicting expert opinions
that emerge in complex cases. An interesting counterpoint to this is
the emergent popularity of "naturalistic decision making" where
judgment is treated as a process that can be described and explained
scientifically. One of the intentions of course is to create expert
systems that can make judgments in place of humans. I suspect that
judgment and decision-making are distinct processes and that one is not
a subset of the other. But I also believe they are quite interrelated
systemically.
Regards
Harold
