Open vs. closed vs. hybrid card sorting for UX research

Card sorting is a widely used method in UX research to understand users' mental models and improve the information architecture of websites and applications. It involves categorizing items to reflect how users organize information, helping designers create intuitive navigation systems. Card sorting can be conducted in various ways, including open, closed, hybrid, and moderated or unmoderated sessions, each offering unique advantages and challenges. This method is cost-effective and flexible, applicable at any stage of product development, and can be conducted in-person or remotely. However, biases and participant variability can affect results, requiring careful planning and analysis. By following best practices such as limiting card numbers and recruiting the right participants, researchers can gain valuable insights into user preferences and behaviors to enhance the user experience.
