A very persuasive argument can be made that the law is the profession most resistant to change.
Stare decisis and the power of precedent hold great sway in the courtroom. New legislation requires all three branches of our government to cooperate in order to become truly effective. Even our professional habits sometimes take generations to evolve. Thus, calling on a lawyer to alter the way he or she practices is a mighty task; most of us, like the stubborn children we all at heart are, will fight that change to the end.
