The Battle for God by Karen Armstrong has been a huge influence in how I view and interact with folks who are resistant to change. While the book itself is about religious fundamentalism, the primary thesis - that fundamentalism is a repeatable, observable reaction of those who feel modernization has been forced upon them and those folks inevitably go on to create something entirely new and unique as a response in their efforts to preserve "the old ways" - is shockingly applicable in a wide range of cases. I've thought about this both while responding to RFPs and chatting with neighbors, for example.
From the preface (or maybe chapter 1, I forget and gave away my copy so I can't check):
Modernization has always been a painful process. People
feel alienated and lost when fundamental changes in
their society make the world strange and unrecognizable.
... Fundamentalists feel that they are battling against
forces that threaten their most sacred values. ... Those
of us — myself included — who relish the freedoms and
achievements of modernity find it hard to comprehend the
distress these cause religious fundamentalists. Yet
modernization is often experienced not as a liberation
but as an aggressive assault.
