    During the latest decade analyses of accidents invariably have pointed to the role of human error and it is often stated that 80-90 % of all accidents are caused by human error. Consequently, considerable resources have been spent on human error research. The concept of human error is,however, very elusive. At a closer look, the frequent allocation of accidental causes to human error appears to rather subjective. This is a simple reflection of the nature of causal analysis. The lecture will present a discussion of the cognitive aspects of errors and the close relationship with human learning and adaptation are discussed. Errors are the reflection of normally very effective cognitive mechanisms in a particular context. Based on this position, some directions for design of error tolerant systems will be presented.
