High refusal rates can significantly impact the validity and representativeness of survey results. Those who refuse to participate may differ from those who do participate in important ways that are beyond the researcher's control, such as demographic or attitudinal characteristics. This can introduce bias into the sample and result in inaccurate conclusions. While refusal rates may be lower in mail surveys, they can still be a problem if non-response is associated with specific characteristics. While it is possible to replace non-respondents with cooperative participants in some surveys (such as in quota sampling), this may not be feasible or effective in all cases.
