Question 1

How quickly are payments processed and disbursed to participants?

Accepted Answer

Once a researcher approves your submission, the payment is credited to your Prolific balance. You can cash out your earnings to PayPal once your balance reaches £5.00 (or equivalent in other currencies). Withdrawals are typically processed within a few business days, though first withdrawals may take slightly longer for verification.

Question 2

What are the eligibility requirements to participate in studies?

Accepted Answer

Participants must be at least 18 years old and reside in one of the supported countries. You'll need to complete a comprehensive 'About You' section in your profile, which helps Prolific match you with relevant studies. Maintaining a good submission history and response quality is also crucial for continued access to studies.

Question 3

Can I use a VPN or proxy server while participating in studies?

Accepted Answer

No, using a VPN or proxy server is strictly prohibited. Prolific's system detects and flags such usage to ensure data integrity and prevent fraudulent participation. Using one will likely result in your submissions being rejected and could lead to account suspension, as researchers often target specific geographic locations.

Question 4

What are the costs for researchers to run a study on Prolific?

Accepted Answer

Researchers pay participants directly for their time, plus a service fee to Prolific. The service fee is a percentage of the participant payment, typically around 25-33%, depending on the study's complexity and participant targeting. There are no upfront subscription fees; costs are incurred per participant completed.

Question 5

How does Prolific ensure data privacy for participants?

Accepted Answer

Prolific acts as an intermediary, connecting participants with researchers. While Prolific itself collects minimal personal data for account management and study matching, the actual study data is collected by the researchers on their own platforms. Prolific emphasizes GDPR compliance and requires researchers to adhere to ethical guidelines, including data anonymization where appropriate, but participants should always review the consent forms provided by individual researchers.
