Possible effects of incentives on data quality:
- Motivation to participate changes. Instead of providing meaningful feedback, the survey becomes an ‘entry’ or ‘ticket’ to get something in return.
- The incentive may influence perceptions of the company, product or research and will therefore influence feedback.
- When you offer someone an incentive, they will complete the survey in the same way that they would return a favour and will feel obligated to do a good job.
- Respondents who receive an incentive are also more likely to say that the survey subject matter was interesting, and this causes them to place a greater value on their task.
