"Individuals are self-activating, self-directed experience instigators, selectors, and evaluators. The genetic propensities with which we are born, including temperament, are the precursors of the general personality and ability traits that will soon take form (Funder, 2001; Lykken, Bouchard, McGue, & Tellegen, 1993). These propensities act like an internal compass, inclining us toward or away from possible forms of experience that we might encounter or create (for example, risky versus safe, people-related versus things-related). We tend toward those we resonate with and away from those that discomfit us. Emitting a constant stream of mostly preconscious feedback, this compass colours our past experiences and influences our future choices. Our genotypes thus help shape both the perceived and actual environments in which we develop. In other words, nature activates and shapes nurture."
