When we build, say, a business area in which all (or practically all) are engaged in earning their livings, or a residential area in which everyone is deep in the demands of domesticity, or a shopping area dedicated to the exchange of cash and commodities—in short, where the pattern of human activity contains only one element, it is impossible for the architecture to achieve a convincing variety—convincing of the known facts of human variation. The designer may vary color, texture and form until his drawing instruments buckle under the strain, proving once more that art is the one medium in which one cannot lie successfully.
Psychologists have noted that people tend to place greater artistic value on images when they can see the work that has gone into them — a tendency known as the “effort heuristic”. They are also more likely to connect emotionally with the work if they can detect the human hand, says Goldsmiths’ Chamberlain. “There’s an argument that if we see a brush stroke, we almost recreate it, and that’s part of the connection we feel with the artist — you can feel the intention.”
Perhaps to capitalize on this, some architects now show presentation drawings that look hand-drawn but are actually generated entirely by computer. “It’s totally fake,” says Brillhart. “They just take a computer image into Photoshop and put filters over it to make it look like it’s drawn by hand. It’s kind of amusing — instead of just sitting down and drawing for an hour, they spend eight hours making it look like a hand drawing.”
You can’t make people use streets they have no reason to use. You can’t make people watch streets they do not want to watch. Safety on the streets by surveillance and mutual policing of one another sounds grim, but in real life it is not grim. The safety of the street works best, most casually, and with least frequent taint of hostility or suspicion precisely where people are using and most enjoying the city streets voluntarily and are least conscious, normally, that they are policing.
