If designers understood more about the mathematics of attraction, the mechanics of affection, all design could both look good and be good for you.
GREAT design, the management expert Gary Hamel once said, is like Justice Potter Stewart’s famous definition of pornography — you know it when you see it. You want it, too: brain scan studies reveal that the sight of an attractive product can trigger the part of the motor cerebellum that governs hand movement. Instinctively, we reach out for attractive things; beauty literally moves us.
Yet, while we are drawn to good design, as Mr. Hamel points out, we’re not quite sure why.
This is starting to change. A revolution in the science of design is already under way, and most people, including designers, aren’t even aware of it.
Take color. Last year, German researchers found that just glancing at shades of green can boost creativity and motivation. It’s not hard to guess why: we associate verdant colors with food-bearing vegetation — hues that promise nourishment.
