After many years of continuous effort and focus, Societal Evolution: The Evolution of Sexual Normality captures Colby's fondness for psychology. In fact, as a student while in college, Colby's original motivation for writing Societal Evolution: The Evolution of Sexual Normality began during a course on developmental psychology. In college, during psychology class, a sudden ideology penetrated Colby's brain. Contemplating on the ideology, Colby realized just how significant the ideology reflected a facet of societal and sexual evolution. Thus, upon even extensive contemplation, Colby developed a complete theory on sexual evolution. Ultimately, as writing is one of Colby's hobbies, he yearned to document his theory. Carefully selecting every thought before eloquently committing them to the written page, Colby eventually documented his entire theory by developing Societal Evolution: The Evolution of Sexual Normality.
