personalities, emphasizing some traits when with families, a different set when with friends. We all change our operating parameters to be appropriate for the situation we are in.
Ever watch a movie with great enjoyment, then watch it a second time and wonder what on earth you saw in it the first time? The same phenomenon occurs in almost all aspects of life, whether in interactions with people, in a sport, a book, or even a walk in the woods. This phenomenon can bedevil the designer who wants to know how to design something that will appeal to everyone: One personâs acceptance is another oneâs rejection. Worse, what is appealing at one moment may not be at another.
The source of this complexity can be found in the three levels of processing. At the visceral level, people are pretty much the same all over the world. Yes, individuals vary, so although almost everyone is born with a fear of heights, this fear is so extreme in some people that they cannot function normallyâthey have acrophobia. Yet others have only mild fear, and they can overcome it sufficiently to do rock climbing, circus acts, or other jobs that have them working high in the air.
The behavioral and reflective levels, however, are very sensitive to experiences, training, and education. Cultural views have huge impact here: what one culture finds appealing, another may not. Indeed, teenage culture seems to dislike things solely because adult culture likes them.
So what is the designer to do? In part, that is the theme of the rest of the book. But the challenges should be thought of as opportunities. Designers will never lack for things to do, for new approaches to explore.
CHAPTER TWO
The Multiple Faces of Emotion and Design
AFTER DINNER, WITH A GREAT FLOURISH, my friend Andrew brought out a lovely leather box. âOpen it,â he said, proudly, âand tell me what you think.â
I opened the box. Inside was a gleaming stainless-steel set of old mechanical drawing instruments: dividers, compasses, extension arms for the compasses, an assortment of points, lead holders, and pens that could be fitted onto the dividers and compasses. All that was missing was the T square, the triangles, and the table. And the ink, the black India ink.
âLovely,â I said. âThose were the good old days, when we drew by hand, not by computer.â
Our eyes misted as we fondled the metal pieces.
âBut you know,â I went on, âI hated it. My tools always slipped, the point moved before I could finish the circle, and the India inkâugh, the India inkâit always blotted before I could finish a diagram. Ruined it! I used to curse and scream at it. I once spilled the whole bottle
all over the drawing, my books, and the table. India ink doesnât wash off. I hated it. Hated it!â
âYeah,â said Andrew, laughing, âyouâre right. I forgot how much I hated it. Worst of all was too much ink on the nibs! But the instruments are nice, arenât they?â
âVery nice,â I said, âas long as we donât have to use them.â

THIS STORY shows the several levels of the cognitive and emotional systemâvisceral, behavioral, and reflectiveâat work, fighting among themselves. First, the most basic visceral level responds with pleasure to seeing the well-designed leather case and gleaming stainless-steel instruments and to feeling their comfortable heft. That visceral response is immediate and positive, triggering the reflective system to think back about the past, many decades ago, âthe good old days,â when my friend and I actually used those tools. But the more we reflect upon the past, the more we remember the actual negative experiences, and herein lies the conflict with the initial visceral reaction.
We recall how badly we actually performed, how the tools were never completely under control, sometimes causing us to lose hours of work. Now, in each of us,
