heijastumisero

Heijastumisero, often translated as "reflection error" or "rebound error" in English, is a concept in Finnish design and psychology. It refers to the phenomenon where an individual's perception of an object or situation is influenced by their own internal state, biases, or expectations, rather than purely objective reality. This can lead to misinterpretations or a distorted understanding of what is actually present.

The term gained prominence through the work of Finnish psychologist and designer, Juha Lehtonen. He explored how personal experiences, cultural background, and even mood can act as filters, affecting how we interact with and judge the world around us. For example, if someone is feeling particularly stressed, they might perceive a simple design as overly complex or even hostile, a heijastumisero in action.

In design, understanding heijastumisero is crucial for creating user-centered products and environments. Designers aim to minimize negative reflection errors by considering diverse user perspectives and striving for clarity and intuitiveness. By anticipating potential subjective interpretations, designers can work towards solutions that resonate more broadly and effectively with their intended audience. It highlights the subjective nature of experience and the importance of empathy in design and communication.
