I was reminded of the concept of “muddled thinking” while reading a recent copy of Business Week. In its October 15th issue, I came across a headline that read: “The Top Design Schools.” Great, I thought. Let’s take a look. Art Center College of Design: no surprise there. Further down: California College of the Arts. No surprise there either. But then sandwiched between Georgia Institute of Technology and Hongik University College of Design appeared the Harvard Business School — which was a surprise, especially since Harvard’s Graduate School of Design was conspicuously absent from the list.
