Why can’t you invite me only to studies I will qualify for or explain the qualification criteria in the invitation?

We invite you to studies that may be relevant based on the information in your profile. Keeping your profile accurate and up to date helps us send you more suitable opportunities, but it cannot guarantee that you will qualify.

Each study has specific requirements that are confirmed through screening questions. We cannot include all qualification criteria in the invitation because sharing them in advance could influence how people answer and affect the accuracy and reliability of the research.

We aim to include enough information in each invitation to help you decide whether you are interested in taking part, while keeping the screening process fair and unbiased.
