Attractive things work better

Excerpts from: Emotional Design, by Donald Norman

The psychologist Alice Isen and her colleagues have shown that being happy broadens the thought processes and facilitates creative thinking...

When you feel good, you are better at brainstorming, at examining multiple alternatives...

Isen's results show that when people are happy, their thought processes expand, becoming more creative, more imaginative...

All these point to one of the main premises of Don Norman's latest book -- attractive things make people feel good, which in turn makes them think more creatively. Consequently, attractive things work better, because people find them easier to use.
