The main question the study sought to answer was whether psychologists attributed the causes to the technical system while engineers attributed them to the humans. After the Three Mile Island accident in 1979, focus has been brought on the human factor issues in the nuclear power community both among industries and regulators.
Different factors are of importance when analyzing incidents and accidents.
This indicates that it is important that engineers and psychologists cooperate when analyzing an incident or accident. Introduction Human behavior is always involved in the cause of an accident. Advances in the design and surveillance of high risk systems have changed the task for man. New technology and more complex systems put new and higher demands on the people working in these systems. One of the major changes is that the operators have been placed further away from the process they are supposed to control.
