Do I trust the vastly larger number of people with whom I have no dealings in those matters? No—but this is not a harsh answer. Most of these are people I do not even know and have no reason either to trust or to distrust. Unfortunately, if we begin to articulate our questions precisely enough to get at such discriminating differences, we virtually have to explain what we are seeking to those we survey (or those whom we put through experiments). We thereby give them theoretical understandings they did not have, and we elicit answers or experimental responses to those understandings rather than to their normal experiences.

XREF: Relates to the observer effect in social science research and the problem of reactivity in survey methodology.
