When you run a survey you are getting responses from people

- who are made aware of the survey
- who are given access to the survey
- who are willing to respond
- who are able to respond

People who are disenfranchised, living with disabilities, struggling with time, money and/or language/literacy generally will not respond.

Surveys are rarely representative because the time and effort required to make surveys inclusive is not invested.

The effect of surveys is then that people who are made invisible by society are made even more invisible by organisations that often call themselves data-driven.

Because they run surveys.
