The information that "most people just hate change on principle" -- in fact, they typically see change as loss -- was a lesson learned from my spiffy corporate training when I worked for a Fortune 500 company and before I could even begin my entry level job, I first underwent three months of training. Among other things, this three months of training involved completing a certificate program in a single month by attending class 7.5 hours a day at a local technical college instead of going to the job site.

It was world class training. I imagine it's pretty solid information even before you take into account how well it fits with firsthand experience that most people just haaaaaaate change on principle, even if it turns out to be the right thing to do and they later decide it was for the best.
