As noted by Park, Sher, Krull, and Wood (2009), individuals tend to self-select into environments that are compatible with their own character or personality. This so-called selection process (Buss, 1987; see also Caspi & Bem, 1990; Plomin, DeFries, & Loehlin, 1977; Scarr & McCartney, 1983) is evidenced in several areas of human behaviors (e.g., peer relationships; Caspi, Roberts, & Shiner, 2005). Notably, since individuals are inclined to act on the basis of their existing characteristics, selection processes based on personality may be especially likely during transitional periods that present a host of choices (Caspi & Bem, 1990).
