During my master Applied Cognitive Psychology, I developed card decks to address cognitive biases in different parts of the design process. One deck focused on reducing biases during qualitative analysis, and the other deck focused on reducing biases during participatory design such as brainstorming or group decision-making. Each card deck consisted of eight cards explaining the bias and providing practical tips or ideas to reduce the bias. The cards could be used during design sprints or workshops to help the participants reduce their biases.
