"I agree with O'Toole that custom and comfort are impediments to change. However, it is important to recognize that resistance to change is logical as well. The new "change masters" literature seems to take change as the norm. It isn't. Humans naturally see change as risky because it is risky, just as mutations in genes are mostly destructive. You would not want to go to work were everything changed every week! The phone system, the office assignments, who reports to who, and the whole set of job expectations."
