What assumption does the trait-and-factor model make about human beings?

The trait-and-factor model of career development is rooted in the belief that individuals have specific traits—such as interests, abilities, and personality—that can lead to successful career choices when matched appropriately with factors related to occupational requirements. The model assumes that with sufficient information about both personal traits and job characteristics, individuals are capable of making informed and wise decisions regarding their careers. This highlights the importance of understanding one's self and the labor market, promoting a rational approach to career planning.

In contrast, the other options reflect assumptions that do not align with the core principles of the trait-and-factor approach. The model does not suggest that humans make irrational choices or that extensive guidance is required, as it emphasizes self-awareness and informed decision-making. Similarly, the notion that people are inherently dissatisfied with their careers contradicts the premise that good matches between traits and job factors can lead to satisfaction and fulfillment. Thus, the trait-and-factor model points towards the capacity for individuals to navigate their careers wisely when equipped with the right information.
