Survey companies are usually looking for a specific criteria of people in who they select to answer surveys.
This means that some surveys won't be right for your personal circumstances, or that the survey has fulfilled its quota of people in your particular demographic. This may mean that after starting a survey, you'll see a screen that says the survey isn't right for you, or that you've been "screened out".
Unfortunately, we don't have any control in the qualifying questions that our third party survey providers ask. Providing accurate, truthful, and consistent answers to all surveys is the best way to avoid this issue.
