Prolific vs. MTurk

How are we different?

Highly reliable data

When testing Prolific, MTurk, CloudResearch, Dynata and Qualtrics, research shows that Prolific produces significantly higher data quality on all measures. This includes attention, honesty, comprehension and reliability. Read the full paper or blog summary.

Free audience filtering

Use all of Prolific's 250+ pre-set filters at no extra cost. Only representative samples cost more. On MTurk, each additional screener adds to your bill.

*Should you need a niche sample of participants we don't have screeners for, contact us.

Representative samples

Get more accurate national conclusions on Prolific using our representative sample feature. Our algorithm will distribute your survey across sex, age and ethnicity within either the US or UK.

Built for multi-part studies

Prolific’s tools help you easily find the same participants and run follow-up studies. You have to manually trace participants on MTurk.

Ethical rewards

Part of high quality research is following universal ethical standards. Unlike MTurk and other platforms, Prolific sets a minimum hourly reward of £6.00 or $8.00 for all participants.

Scientific expertise and support

Prolific is designed by researchers for researchers. That's why set up is so quick and easy – think 15 minutes, not hours. Our support team comes with extensive training too. Ask us for anything you need or view our Help Centre.

Message participants anonymously

Prolific protects researcher and participant privacy. Our research rules and anonymous in-app messaging system help you chat freely and safely about your studies.

Large active participant pool

MTurk doesn’t list how many active participants they have, but claim to have a total pool of 500,000. Prolific has 130,000+ active participants, with 800,000+ total pool size.

Self-service on demand

Prolific is built to put researchers in control. Recruit participants when you need them and collect data at 10x the speed of traditional research methods.

Fast study completion

The average study takes 2 hours to complete on Prolific, and MTurk is speedy too. Completion time depends mainly on your audience and study length.

Affordable pricing

Both are affordable, but Prolific’s free audience filters and reliable data help remove hidden costs. Prolific’s minimum reward is $8.00 per hour + 30% service fee for industry customers, or 25% service fee for academics and non-profits. MTurk’s minimum is $0.01 per task + 20% service fee (or 40% for 10+ tasks). Whilst MTurk can be cheaper, paying to prescreen and replace unreliable data can quickly increase costs.
