In principle, making good group decisions is really hard, a lot harder than making bad decisions. Making peace is much harder than making war. Getting along with each other and making good, lasting decisions takes a lot of practice. “Act” is part of the word “practice.” We do not get better without action. We do things poorly until we can do them well. It is not so important that we succeed, but that we try.
Practical Tip: Practice the principles of good group decisions as best as you can. For guidance ask yourself, “What would a peaceful person do?” Do not just talk about how to make peaceful decisions, or read about it, or think about it, but practice making good group decisions. Most of us are not very good peacemakers but when we try to act as if we were, our world becomes more peaceful.
