“…Observers of the person in different situations may rate the individual on various traits ("Situation Data," Table 2). Such informant reports are especially important given that a group of theories argue that a person's inner sense of self develops from their interactions with others and from how others perceive them (e.g., Cvencek et al, 2021;Felici et al, 2023).
