Effort tasks are commonly used to assess individual investment and performance in an experimental setting. Although the tasks used are diverse, they are typically intended to be equivalent as far as they aim to generalize beyond the specific task. We compare an induced value effort task and...

As a stress test of experimenter demand effects, we run an experiment where subjects can physically destroy coupons awarded to them. About one subject out of three does. Giving money back to the experimenter is possible in a separate task but is more consistent with an experimenter demand effect...

Behaviour in public good experiments is usually attributed partly to rational self-interest and partly to social norms and preferences. This paper examines if sensitivity to social desirability affects public good contribution and in what way. A pre-experimental measure of social desirability...

Public good contribution in experiments may at least partially be driven by the social demand to contribute that is implicit in them. We consider a questionnaire measure and build a behavioral measure of sensitivity to social pressure based on paired dictator and money burning games; we find...

The effectiveness of a medical treatment should not predict its risk (highly effective treatments can be either safe or risky), however, people's use of heuristic shortcuts may lead them to judge a link between effectiveness and risk, typically a negative correlation. A particular concern is...

Public good contributions may be affected by the social demand to contribute that is implicit in them. Sensitivity to social pressure predicts behavior in paired dictator and money burning games; the evidence for effects on public good contribution is mixed.
