I find the second group more often than not so pendantically afraid of building something even a few lines of any sort of "anti pattern" that when they meet the messy qualities of reality they fail to build anything, or at least take 20x as long as the first group.
Eh. That's not inherent to the second group. I think that's what happens when the second group is disempowered---both by the organization and by the hellish landscape of technology they have to work with. It can be very paralyzing to try to do something right when the tools are all broken.
Or maybe a good team is a mix of the two. I dunno. But I know that not having theory gets you only so far, and then everything becomes awful.
