Exploring the Essence of Simplicity in Design from a Scientific Viewpoint
In the realm of psychology and design, understanding the intricacies of human perception and decision-making has been a long-standing quest. This quest has led to numerous groundbreaking discoveries, shedding light on the complex interplay between our conscious and unconscious minds.
One of the key findings in this area comes from the work of John Dylan Haynes, a renowned neuroscientist. In a 2007 experiment, Haynes demonstrated that brain activity patterns could predict an individual's decision up to seven seconds before the conscious decision-making process [1]. This finding challenged traditional views by showing that the brain "decides" before the person consciously experiences the choice, suggesting that unconscious brain processes precede and likely cause the subjective feeling of intention.
This experiment, which used functional magnetic resonance imaging (fMRI) along with advanced pattern recognition algorithms, provided important evidence about the neural basis of volition and decision-making [1]. It revealed that specific neural patterns correlate with choices even before conscious recognition, highlighting the crucial role of unconscious processes in our decision-making.
This revelation has significant implications for design, particularly minimal design. Minimal design, which aims for simplicity and transparency, is well-suited for the novice brain because it doesn't assume anything and doesn't challenge, reducing inattentive blindness and increasing the user's ability to recall buttons, options, and functions [2]. This is supported by the Magical Number Seven, Plus or Minus Two study, which suggests the importance of having as few design elements as possible due to human short-term memory's limitations [3].
However, minimal design is not enough for experts in a particular field, who tend to put a lot of attention into their area of knowledge. Complex software UIs designed for experts are often impenetrable for the novice and the uninterested, as they may contain too many options and stimuli [4]. This is where the principles of the Gestalt school of psychology come into play. The Gestalt school concluded that human perception tends to find the simplest, most stable, and symmetrical shapes in reality, due to the concept of "Prägnanz" or "pithiness" [5].
Designers must strive to bypass the limitations of the conscious mind and reach a deeper, subconscious level in which communication becomes instantaneous, automated, and direct [6]. This requires an intimate understanding of the perception and recognition processes, not just of humans, but also of machines, as designing for robots is a growing field [7].
The human brain has limitations in short-term memory, capable of recalling around seven items with high accuracy [3]. This limitation, coupled with the fact that human consciousness is responsible for only a fraction of our actions, raises ethical and philosophical implications regarding the limitations of conscious will and the extent of unconscious processes [8].
These findings, from the principles of minimal design to the experiments on inattentional blindness and decision-making, have transformed our understanding of how we perceive and make decisions. As we continue to uncover the mysteries of the human brain, we can expect design to evolve in ways that better cater to our cognitive processes, bridging the gap between the conscious and unconscious mind.
