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
Constrained by the medium The inevitable reciprocation that occurs between the act of drawing and the thinking associated with it. The hand moves, the mind becomes engaged, and vice versa. We might ask: How much does the medium of expression actually constrain a design process? A medium has a way of constraining our choices, and this influence may not involve conscious choice at all. The planner, in the end, sees and understands only those things for which they can provide expression. Peter G. Rowe, Design Thinking Michaelangelo's hammer constraintsexpressionmedia
