No. We don’t need religion to make good decisions. And by religion, I mean that which differentiates it from other community organizations:
• belief in the supernatural and the superstitious (a god being, prayer, miracles) and
• faith in the infallibility of ancient texts or the authority of the priestly class (bible, koran, pope, preacher, etc.).
Decision making ought to be based on the best facts that one can surmise. Since we know that ancient texts are often filled with barbaric cruel immoral contradictory stories (see the Bible) written by a multitude of men for a multitude of ancient cultures, they cannot be the best source of wisdom when deciding things today.
These facts ought to based on reality or as close an approximation to reality that is currently available. The Scientific Method (and its handmaiden: Technology) is the best tool we have for investigating reality. With science, we separate fact from wishful thinking (an afterlife, angels, psychic power). With science, we separate fact from superstition (prayer, ghosts, curses, hell).
Reality ought to be based on evidence. Evidence is the foundation of science. And evidence ought to be the foundation for good decisions. Not supernatural beliefs, not superstitions, not faith in ancient texts, not adherence to dogma, not anything non-reality based.
Therefore, the best decision making from the minute (or individual) to the grand (or governmental) ought to be based on facts, based on reality, based on evidence.
And most people already live their lives in this way. People insist their transportation, medicine, food, buildings and utilities meet strict scientific standards. People insist their professionals: doctors, lawyers, engineers, technicians, and mechanics are trained according to strict scientific standards.
