Scientific identity and STEMM-relevant outcomes: Elaboration moderates use of identity-certainty☆

This research investigates the link between scientific identity and STEMM (Science, Technology, Engineering, Mathematics, and Medicine)-related outcomes as a function of identity certainty. Across a pilot study and three additional studies, participants' scientific identity was first measured using different procedures. Then, the certainty with which that identity was held was either measured (pilot study and Studies 1 & 2) or manipulated (Study 3). Both subjective outcomes (e.g., interest and career decisions in the pilot study and Study 2) and objective consequences (e.g., performance in Studies 1 and 3) served as dependent variables. As expected, results showed that participants' scientific identity was more strongly associated with STEMM-relevant outcomes as certainty in that identity increased. Beyond predicting when and for whom scientific identity is more likely to guide career decisions and performance, this research showed that reliance on identity certainty (a metacognitive assessment) is more likely to occur as the extent of thinking is increased. By inducing elaboration after certainty was already manipulated (Study 3), this research distinguishes between forming a metacognitive judgment of certainty and subsequently using that already existing certainty.
