You may notice more "study full" or "high demand" messages than usual. This is expected right now while we make some improvements. It's not a problem with your account, and there's nothing wrong on your end. Here's what's going on, and what to expect.
What's happening
We're improving how we distribute studies across Prolific. As more researchers run studies with us, we're upgrading the systems that match the right studies to the right people, so the platform stays fast and reliable for everyone. While we roll these improvements out, studies can fill up more quickly than you're used to, so you may click into a study and find it's already full or in high demand.
What this means for you
We know it's frustrating to click into a study only to find it's full. This is temporary and it's affecting Prolific as a whole, it's not a problem with your account. You may notice it more if you use the platform often, simply because you're browsing more studies.
Your approval rate and account status are unaffected. If a study is full, head back to your dashboard and try the next one. You may need to check more often than usual to find available studies.
How long will this last?
We're working to resolve this as quickly as we can, and we expect it to improve over time. We'd rather get these improvements right than rush them, so we're not putting an exact date on it. We'll update this article as things change.
Do I need to contact support?
