ABSTRACT
Having spent 50 years as a researcher in psychology, I have the chance here to reflect not only on the chapters in this volume, but also on what I have seen over my decades of observation and active involvement in this field in particular, and in science and society more generally. I have always been partial to the big picture and the long view, so allow me to paint some broad strokes that might make these collected chapters stand more distinctly in context—they represent a major enhancement in the scope and reach of our field, and position us better to contribute to the greater good. What you will find here are some reflections about mental models, parsimony, the maturation and vitality of our field (which is more than just the passage of time and mere aging), and the many shades of gray and the many hues and saturations of color that reside between black and white.
