Motivation -Abstract surveys are currently the primary source of data guiding policy-makers as they frame laypeople's choices to electronically share their health information with care providers.

... choices, their rationale for their choices, and their recommendations for other patients were contrary to what might be expected, given abstract survey responses.

Originality/Value -Walking decision-makers through realistic decision scenarios, and asking them to provide recommendations to other patients allowed us to assess laypeople's true decision criteria. This research therefore demonstrates the value of using realistic decision scenarios to inform policymaking.
