IV1: Outcome [Between]	IV1: Outcome manipulation Outcome: Success	IV1: Outcome manipulation Outcome: Failure
IV2: Decision-maker [Between]	Manipulation: ‘The operation succeeded.’	Manipulation: ‘The operation failed.’
IV2: Decision-maker manipulation condition A Decision-maker: Patient Manipulation: Participant was told ‘the patient decided to go ahead with the operation’.	Dependent variables Decision quality: ‘Please evaluate the physician’s/patient’s decision on a scale from 3 (Clearly correct and the opposition decision would be inexcusable) to –3 (Incorrect and inexcusable).’ Perceived outcome importance: ‘Do you think you should take the outcome into account in evaluating the decisions? Please rate on a scale from 1 (Definitely not) to 5 (Definitely yes).’ Perceived responsibility: Item: ‘Rate the level of responsibility of the patient for the decision made to go ahead with the operation on a scale from 1 (No responsibility) to 7 (Full responsibility).’ Perceived norms: Item: ‘Do you think that most people in this situation would decide to go ahead with the operation? Please rate on a scale from 1 (Definitely not) to 5 (Definitely yes).’
IV2: Decision-maker manipulation condition B Decision-maker: Physician Manipulation: Participant was told ‘his (the patient’s) physician decided to go ahead with the operation.’
