The extent to which groups are creative has wide implications for their overall performance, including the quality of their
problem solutions, judgments, and decisions. To further understanding of group creativity, we integrate the motivated information
processing in groups model (De Dreu, Nijstad, & Van Knippenberg, 2008) with work on epistemic social tuning (Lunn, Sinclair,
Whitchurch, & Glenn, 2007).
Three propositions were advanced: (a) Groups produce more ideas when members have high
rather than low epistemic motivation, especially when members also have a prosocial rather than pro-self motivation; (b) these
ideas are more original, appropriate, or feasible when a group norm favors originality, appropriateness, or feasibility; and
(c) originality is valued more in individualistic cultures (e.g., the Netherlands), whereas appropriateness is valued more
in collectivist cultures (e.g., Korea). Four studies involving 3-person groups generating ideas supported these propositions:
Epistemic motivation (mild vs. intense time pressure; presence vs. absence of process accountability) stimulated production
originality, especially when prosocial rather than pro-self motives were present and participants were Dutch or originality
norms were experimentally primed. When appropriateness norms were primed or participants were Korean, epistemic motivation
stimulated production and appropriateness, especially when prosocial rather than pro-self motives were present. We discuss
implications for research on group processes and for work on culture and creativity.
