(I’m providing the following information as a public service, but for the purposes of full disclosure I’ll note that I secretly hope it will result in less survey requests coming to me..)
1. There’s a type of person that likes to fill out surveys. Unfortunately they are not the person you want filling out your survey, as they don’t represent a cross-section of your target audience.
2. There’s a special case, whereby a person is not the type of person that like to fill out surveys, yet they are so ticked off at you, that they jump at the chance to lash out at you. Unfortunately they are not the person you want filling out your survey either, because they make you look really bad, and have trouble staying objective.
3. All the rest of the people aren’t going to fill out your survey. If you do force or coerce them, it is going to make the data obtained useless.
In short, if you think you need a survey, it probably indicates a deeper problem that a survey is not going to solve.
