The (un)compromise effect

New working paper "The (un)compromise effect" from Mathias Ekström.

Abstract from the Working Paper

The current study provides the first experimental test of the compromise effect, i.e. the tendency to choose middle options, in a naturally occurring setting. Simultaneously, I pro- pose and evaluate a novel nudge intended to stimulate active choice—the (un)compromise effect—a compromise effect without an explicit middle option. 63,494 recipients of a mail fundraiser were randomly assigned to one of three sets of suggested donations: [$10, $50, $100, $ ]; [$10, $50, $100, $250, $500, $ ]; or [$10, $500, $ ].

Johan Egebark and Mathias Ekström test in their new paper "Liking what others 'Like': using Facebook to identify determinants of conformity" whether users are more prone to support content if someone else has "Liked" it before.

The results support both the compromise effect and the (un)compromise effect: extending the range increased the fraction donating $100 as well as the average donation—independent of whether the middle suggested donations were present or not. Hence, by only providing informative end points, organizations can affect decision-making and at the same time promote individuality through active choice. The results also shed light on why suggested alternatives affect choice in general: they reduce the cognitive cost of figuring out what actions are appropriate.
