"Information complexity refers to the data volume inherent in many complex applications and the interaction behaviors (e.g., exploring, filtering, zooming and modeling) required to navigate and analyze such data sets. (This layer is somewhat related to integrative complexity, as huge data sets may be dispersed among unlinked subsystems.)"

Designers need to be careful to manage the amount of information on screen so that it relevant but not overwhelming

Information complexity can be time-consuming and confusing to the end user.
