In the interests of not biasing anyone who may take the survey, I suggest that we stop discussing the validity of any of the scenarios in the survey. I believe I understand why the scenarios are constructed in the ways they are, and that they are valid in context - I also think the study as described has genuine value regardless of whether you would find yourself specifically in some of the situations described.
Let's give Melinda the benefit of allowing people to take the survey without being unduly biased.
