Two independent judges also selected the best idea from participants’ set of self-generated ideas. Under the latent class conceptualization, a class with high levels of growth mindset and creative personal identity, and low levels of a fixed mindset showed higher levels of accurate idea selection and creative self-efficacy than the rest of the classes.
