High refusal rates are a major source of error because those who refuse to participate are likely to differ in important respects from respondents, leading to non-response bias. Personal interviewing may also have higher refusal rates than mail surveys, but this is not the main point addressed in the question. While refusal rates may be beyond a researcher's control, it is still important to understand and address the issue to minimize non-response bias. Simply replacing non-cooperative respondents with others may not fully solve the problem of non-response bias.
