Auswirkungen des Decoy-Effekts auf die Algorithm Aversion

Markus Lorenz

sofia Diskussionsbeiträge 2022, No. 3 https://doi.org/10.46850/sofia.9783947850013

Limitationen im menschlichen Entscheidungsprozess schränken das technologische Potenzial von Algorithmen ein, was auch als „Algorithm Aversion“ bezeichnet wird. In dieser Studie wird anhand eines Laborexperiments mit Probanden untersucht, ob ein seit 1982 unter dem Namen „Decoy-Effekt“ bekanntes Phänomen geeignet ist, die Algorithm Aversion abzubauen. Bei zahlreichen analogen Produkten, wie Autos, Getränken oder Zeitungsabos, hat der Decoy-Effekt bekanntermaßen einen starken Einfluss auf das menschliche Entscheidungsverhalten. Überraschenderweise werden die Entscheidungen zwischen Prognosen von Menschen und Robo-Advisors (Algorithmen), die in dieser Studie untersucht werden, durch den Decoy-Effekt überhaupt nicht beeinflusst. Dies gilt sowohl von vornherein als auch nach dem Beobachten von Prognosefehlern.
