The primary disadvantages of mail questionnaires are that the response rate may be low, and the respondents may not be representative of the population. High mailing costs and decreased validity due to anonymity can also be drawbacks, but they are not as commonly cited as the other two factors. Inconvenience for respondents and potential bias/dishonesty in responses are not specific to mail questionnaires and can occur in other survey methods as well.
