How Shapes Impact Behaviour: Curves, Angles, and Their Profound Effect on Us
Shapes are more than just visual design elements—they profoundly influence our emotions, behaviour, and how we interact with the world. Research into psychology and aesthetics shows a near-universal preference for curved contours over sharp, angular forms. But why is this? The answer lies in our evolutionary wiring and its impact on our perception of safety and threat.
The Science Behind Curves and Edges.
Curves are inherently inviting, activating regions in the brain associated with reward and pleasure. These soft, flowing forms evoke comfort and approachability, fostering a sense of safety and ease. In contrast, sharp edges reminiscent of claws, teeth, or other natural threats stimulate the brain's fear-detection systems, triggering heightened alertness and even stress responses.
This primal reaction has deep psychological implications. Studies, such as one conducted by the University of Haifa, revealed that individuals exposed to environments filled with sharp, angular art displayed significantly more aggressive behaviour compared to those surrounded by soft, rounded forms. These findings highlight how something as simple as shape can influence interpersonal interactions and emotional states.
Architecture’s Impact, a case study.
One striking example of how shapes can polarize perception is the 2007 extension to the Royal Ontario Museum (ROM) in Toronto, designed by deconstructivist architect Daniel Libeskind. The structure’s sharp angles and fragmented forms aimed to be bold and provocative but instead alienated many museum patrons.
The building’s jagged appearance elicited such strong negative reactions that long-time visitors vowed never to return. In 2009, it was ranked the "8th Ugliest Building in the World" by Virtual Tourist, and The Washington Post & CBA News amongst other media publishing platforms named it the "Ugliest Building of the Decade."
These reactions underscore how angular, aggressive designs can create discomfort and even hostility in the spaces we inhabit.
Th Universal Impact of Shapes and Behaviour:
Research suggests that the shapes surrounding us not only influence our feelings but also our behaviour. Curved environments encourage relaxation, positive social interactions, and even cooperation. On the other hand, angular designs can provoke tension, unease, and even aggression.
As famed architect Antoni Gaudí once said:
"There are no straight lines or sharp corners in nature. Therefore, buildings must have no straight lines or sharp corners."
This philosophy is supported by modern science. Environments that mimic nature's organic curves are inherently more inviting and harmonious, promoting emotional well-being and constructive behaviour.
Where can this be see in Everyday Applications?
Understanding the psychological effects of shapes is a valuable tool for architects, designers, and planners. By incorporating softer, rounded contours into designs, they can create spaces that promote emotional health and social harmony.
Workspaces: Rounded furniture and layouts can reduce stress and foster collaboration.
Homes: Soft, curved elements in interiors create a sense of warmth and safety.
Public Spaces: Organic shapes encourage exploration, connection, and relaxation.
So then why does shapes matter?
Shapes and contours are not just aesthetic choices; they profoundly affect how we feel, act, and interact with others. From ancient instincts of survival to modern debates in architecture, the evidence is clear: soft, inviting forms are more than pleasing to the eye. They’re vital for fostering positive experiences.
As philosopher Gaston Bachelard beautifully said:
"The house shelters daydreaming, the house protects the dreamer, the house allows one to dream in peace."
By understanding and applying the science of shapes, we can craft environments that do more than function—they inspire, comfort, and connect.
