Promise Anonymity or Confidentiality, Probe, Prompt, Use Props, Con, and Tinker for More

Survey researchers seek, and usually obtain, more response and reports, not only when (as discussed in the previous Chapter) they persist, tailor, and so on but, also, also when they promise anonymity or confidentiality, probe, prompt, use props, con, and tinker. These efforts for more affect answers and, thereby, contribute to The Problem.
