The effort heuristic 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.” Nick Jones, Back to the Drawing Board liespsychologydeception
The heart of systems engineering While the client has some knowledge of his symptoms, he may not understand the real causes of them, and it is foolish to try to cure the symptoms only. Thus while the systems engineers must listen to the client, they should also try to extract from the client a deeper understanding of the phenomena. Therefore, part of the job of a systems engineer is to define, in a deeper sense, what the problem is and to pass from the symptoms to the causes. Just as there is no definite system within which the solution is to be found, and the boundaries of the problem are elastic and tend to expand with each round of solution, so too there is often no final solution, yet each cycle of input and solution is worth the effort. A solution which does not prepare for the next round with some increased insight is hardly a solution at all. I suppose the heart of systems engineering is the acceptance that there is neither a definite fixed problem nor a final solution, rather evolution is the natural state of affairs. This is, of course, not what you learn in school, where you are given definite problems which have definite solutions.
