Survey escape options: when to use each

Table of four escape options: None of these, Other, Not sure and Prefer not to say, with when to use each, wording that works and when to leave it out.
Each escape option fixes a different gap in a list, so pick it by the gap.

A table of the four escape options in survey and interview choice questions: None of these, Other, Not sure and Prefer not to say. For each it gives when the option belongs, wording that works and when to leave it out. Use it when you write a choice question and want an honest way out without inviting lazy answers. In Koji you can keep these options at the bottom while the rest of the list is shuffled.
