“…For example, Grawitch and his colleagues (Grawitch, Munz, Elliott et al, 2003;Grawitch, Munz, & Kramer, 2003) found in two laboratory studies that, ceteris paribus, happy individuals working together are more creative than other groups. Similarly, Kelly and her associates (Jones & Kelly, 2009;Kelly & Spoor, 2007) found support for the idea that a group's shared negative affective tone communicates a problematic environment, thereby prompting more persistent efforts to discover a creative solution to a problem (rather than settling prematurely on inferior solutions).…”
