Koolhaas pointed out that decision-makers in countries like China tend to be younger, and therefore are more willing to take on newer and more adventurous aesthetics.
“My final conclusion, and this surprised me, is that the thing that matters most when it comes to designing buildings around the world is the age of the decision maker,” said Koolhaus, who is a professor at Harvard. “In China, the decision maker is 35, in Europe, the decision maker is 55. In America, the decision maker is a trustee, so they might be older.”
“Age is correlated with an appetite for risk,” Koolhaas said.
