Social identities impact the way individuals see themselves and their career options but career theories have been slow to the call in exploring how social identities interface with theoretical assumptions. The purpose of this study was to examine how social identities affect and inform specific dimensions identified by cognitive information processing (CIP) theory as being essential for effective career decision-making, that is, self-knowledge, options knowledge, decision-making process and skills, career beliefs, and overall career decision. Seventy-six students across ten sections of an undergraduate CIP-based career development course answered questions on an anonymous survey related to how their social identities impacted aspects of their career decision-making. Frequencies for social identities were calculated for each CIP dimension, and 11 categories identified for open-ended responses using the consensual qualitative research-modified approach accompanied pre-determined domains based on CIP theory. Across each component, the most common SI was age and generational differences. While students expressed the influence of social identities as occurring in each CIP dimension, statements related to the self-concept category occurred most often and were present in each domain. Our findings support previous work that the presence and impact of SIs on career decision-making components is undeniable, but also not universal. CIP theory provides a structure and avenues for discussing the role of social identities in career decision-making.
