Apply for membership
For methodological research reasons, we can not allow self-registration of members. It is therefore crucial that email lists, newsletters and online advertising at reputable web sites provide specific criteria, enabling us to select members we just need. Please understand that we cannot accept each application of interested persons.
You now have the opportunity to apply for a membership at opinion people.
We'll ask for some basic socio-demographic information and will send you an invitation as soon as we are in need of members.
