Few studies have examined how individual traits affect problem-solving behaviors in engineering design settings. Our study examined the Preferences for Creativity Scale (PCS) and Kirton’s Adaption-Innovation inventory (KAI), and compared it to creativity of the ideas generated and selected. Results show PCS predicted participants’ propensity for creative concept selection. Specifically, team centrality and influence and risk tolerance significantly contributed. KAI predicted generation of creative and original ideas, and propensity for quality concept selection.
