We can create the warm, nurturing world we want by richly reinforcing prosocial behavior. We need families, schools, workplaces, and neighborhoods filled with praise, recognition, rewards, hugs, attention, laughter, caring, and interest. If we do that we will increase all kinds of cooperation, caring, and effort.
After nearly forty years in the behavioral sciences, doing empirical research and publishing papers in important (harrumph, harrumph) journals, I have a reaction to writing this: that it will seem so loose and unscientific. All you need is love! Sure. Right. That song was written forty years ago, but the world doesn’t seem a whole lot better.
