Concepts of problem and solution space are used to describe the design process. In this paper, confirmation bias is presented as an influencing factor on the problem space. Protocol and eye tracking data are used to assess information acquisition, misinterpretation and their effect on designers. The results show that disconfirming and neutral information is misinterpreted as confirming, leading to the acceptance of false problem causes. Low visual attention is a possible cause for this. Whilst information recognized as disconfirming is usually interpreted correctly. These results suggest that designers should more often use disconfirming evidence to challenge and refine their image of the problem space.

问题和解决方案空间的概念用于描述设计过程。在本文中，确认偏差是影响问题空间的因素。协议和眼睛跟踪数据用于评估信息获取，误解及其对设计人员的影响。结果表明，不肯定和中立的信息被误认为是确认，导致接受错误的问题原因。视觉关注度低可能是造成这种情况的原因。尽管通常认为正确解释了确认为不一致的信息。这些结果表明，设计人员应更多地使用不确定的证据来挑战和完善问题空间的形象。
