I don't think these category pairs are completely over-lapping. I don't even know if I am inside the system. I am an idealist revolutionary (;-)). I am probably also a technocrat, and probably part of Jérôme's "core group". And at least my object blogging seems widely enjoyed by the non-technocrat, non-science-ist, non-core-group people; who BTW can be both idealist and realist resp. incrementalist or revolutionary. So I don't see these dualist characterisations as helpful at all.

There are two kinds of people: those that accept dualist characterisations, and those that don't! ;)
Snark aside, my point was not to split people, but to note some of the issues that do divide us (not necessarily with the same people in the two groups each time, far from it) - and the need to avoid wasting our energy on amking these differences bigger than they are. In the long run, we're all dead. John Maynard Keynes
