Perceptual Contrast in Negotiation
In 1974 Philippe Petit walked a high-wire, unassisted and without a safety net, strung between the tops of the World Trade Centre’s twin towers. Petit and his team’s preparations spanned six years and included constructing a scale model, access and entry planning, weather effects and how to rig a cable across the span. Petit even rented a helicopter to take aerial photographs and was reported to have said that having had the opportunity to see things from the vantage point of the helicopter helped, as it had made the actual wire seem not as high. Why? Perceptual contrast.
