Research Wonder: Response Motivation - Important for Survey Data Interpretation

What's a Research Wonder?  Read this to find out...

Most agree that people have numerous motivations to participate in research.  In a recent article, Florian Keusch thoroughly details the various reasons why people participate in web surveys.  It is clear that there is no single reason -- societal characteristics, individual characteristics, and survey characteristics all play a role.  But like most strong literature reviews do, it left me with this...

I wonder if we could start to capture the motivation(s) that play a role in causing respondents to respond so that we may use them in interpreting the data?  

OK, I know, that's a big one.  Let me get a bit more specific with this three-part Research Wonder:

I wonder...

If an appreciation for the contribution(s) that scientific studies make towards a society is a characteristic that may influence one's decision to participate in a survey.

And I wonder...

If we could capture this phenomenon by inviting respondents to follow through with an action (post-survey) that shows their interest in the survey results, for example, suggesting that a respondent could "like" a research study Facebook page or send an email to the study investigator if they are interested in seeing study results when they are available.

And I also wonder...

If this motivation has an impact on WHO responds, and HOW they respond to the survey.
