This paper proposes that given today's "wicked" problems (Malhotra, 1997), where there are complex issues with no clear answers, where boundaries are fuzzy and the outcome is usually never known and unexpected, creativity can be enhanced, at appropriate moments, by making modes of thinking explicit. Using a particular heuristic approach known as the "Six Thinking Hats" (de Bono, 1990), in group critiques and tutorials, students are empowered to suspend judgement at critical moments in a project, and thus, enhance their creativity. Furthermore this approach promotes confidence, openness, and trust such that students speak up more and participate fully, contributing to their peers as well as developing their own ability for self-reflection.
