In dubio contra reo? Anchoring effects as biases in juridical decision making and possibilities for their correction
Project management at the University of Würzburg:
The anchoring effect - the assimilation of numerical judgments under uncertainty towards a previously considered anchor value ? proofs to be an extremely robust bias. Building on research on judgmental anchoring (Tversky & Kahneman, 1974) the present investigation examines in the juridical context whether a sentencing demand has a direct influence on a given sentence. Using criminal trial judges as participants recent studies in the juridical context revealed dramatic anchoring effects in the courtroom: Sentencing decisions in criminal cases are influenced by a given sentencing demand (the anchor), even if it is given by a non-expert, shouted in from the audience or obviously just drawn by fortune. In this research project we work on the question, how to correct for this bias.
