Judgement, Decision Making, and Social Psychology

The research group JDMS (Judgement, Decision Making and Social Psychology) consists of researchers interested in judgement, decision making and social psychology, and especially decision making in societal and other social settings. Our work is oriented towards basic research and applied research, as well as interdeciplinary science.

Research areas

How do we make decisions? How do we make judgements that we base our decisons on? Decison making takes many different forms, such as individual, group, or on organizational levels. It affects both private life and societal development in decisive ways. Research on decision making rests on theories in psychology (mainly cognition-, social-, and organizational psychology) but also other fields such as economy, game theory and organizational theory. The way we make decisions depends largely on how we perceive the decision context, but our choices may also depend on our traits and the surrounding environment.

Social psychology in the context of decision making concerns how people constantly are affected by others’ actual, implied or imaginary presence. This applies not least when we make decisions about and judge other people, as well as how we behave towards them. Social psychology therefore is a key component in research on decision making, and gaining a better understanding of decision making processes contributes to societal development in general.

Courses in decision making and judgement

The Department of Psychology provides a number of individual courses specifically related to our research area:

  • Judgement and decision making, 30 hp (PX1115, Grundnivå)
  • Psychological perspectives on economic behaviour, 15 hp (PX2115, Avancerad nivå)


Many aspects of our area of research also integrates into other, more applied courses, such as environmental psychology, and psychology and law, taught at both basic and advanced levels.
For those who wants to immerse themselves in the psychology behind decision making, the research group offers supervision for undergraduate and masters level, and supervision for PhD candidates. Please contact us for more information.
