Participation in the survey is voluntary. Answering individual questions is also voluntary. If you cannot or do not wish to answer a specific question, you can generally skip that question and go to the next one without any problems. This does not apply to “filter” questions, which lead to different follow-up questions depending on the response. These kinds of questions must be answered in order to enable correct forwarding within the survey.
Please note that especially with regard to personal information, we are not interested in individual responses, but instead are striving to obtain overall results that are as representative as possible. Every question you answer helps us review how representative the results are.
