Who can take part in paid research studies, and which ones: age, countries, professions

Three general conditions

The first condition is age. Prolific accepts only people over 18 with a created and verified account, and researchers are prohibited from recruiting minors. Askable allows sign-up from age 13, but for people between 13 and 18 a parent or guardian must read and agree to the terms.

The second condition is where you live. Prolific states that eligibility is based on where you currently live, not your nationality. User Interviews publishes a separate list of countries where you can take part. Askable operates in many countries but not all, and you can check yours when creating an account.

The third condition is an honest profile. Every study looks for specific people, and platforms cross-check your answers. Untrue screener answers are the fastest way to lose an account.

Countries: where the big platforms work

Prolific publishes its country list. It covers most OECD nations, including the US, the UK, Canada, Australia, Germany, France, the Netherlands, Poland, Spain and Italy, as well as Brazil, Mexico, India, Indonesia, South Africa, the UAE and others. Ukraine is not on the list. Ukrainians living in another country on the list can take part as residents of that country.

Everyday consumers

The largest group of studies is about everyday life. Respondent gives examples: studies about grocery shopping or travel are open to a general audience with relevant experience. Companies need people who actually use their product or service, or a competitor’s.

What researchers most often want to know: how you shop, which apps you use, how you choose a bank or insurance, how you plan a holiday, how you look after your health. The profile of an "ordinary person" is still a profile, and it gets paid.

Professionals and B2B

The best-paid studies are for professionals. Respondent says senior B2B roles regularly pay $400 or more per session. Companies that sell software, equipment or services to businesses want to talk to the people who make buying decisions: IT managers, finance staff, marketers, doctors, lawyers, heads of department.

For professionals it is important to state your job title, industry, company size and area of responsibility precisely in your profile. Researchers filter participants by exactly these fields. Sometimes a platform asks you to confirm your role, for example through a LinkedIn profile.

Special groups researchers look for

Some profiles are in particularly high demand because they are hard to find.

• parents of children of a certain age: for studies of products, education and apps
• owners of specific devices: a particular phone model, smartwatch or car
• users of specific services: a bank, streaming, delivery, work software
• people who have just made a big decision: moved, bought a home, changed jobs
• speakers of languages other than English: for studies of local markets
• gamers: for testing games before release

Formats: what you will actually do

User Interviews publishes ranges by format, and they show how different taking part can be: from a ten-minute survey to a diary kept for several weeks.

Why you might not be selected

Being screened out is not a judgement of you as a person. A researcher may be looking for, say, ten people of a certain age from a certain city who use a certain service. If the places are filled, or you do not match one field, the screener closes. Respondent says it directly: some studies look for specific professional backgrounds, but many are open to everyday consumers, so you will qualify for some studies and not others.

Askable says the same: anyone who meets the conditions can join, but each study targets specific demographics, so members will qualify for some studies but not others. The practical conclusion is to treat rejections as part of the process and keep applying, rather than changing your answers to fit.

• the study has already filled its places
• your profile did not match one of the criteria
• you recently took part in a similar study
• your screener answers contradict your profile

How to get into studies more often

The practical conclusions from the platforms’ rules are simple.

• complete your profile in full: the more fields, the more studies can see you
• update your profile after changes: a new job, a move, a new device
• answer screeners honestly and consistently
• apply quickly: places fill within hours
• sign up on several platforms that operate in your country

How much different profiles are paid

Pay depends not only on format but also on how rare your profile is. Respondent gives reference points for its platform: most sessions pay $50–250, focus groups and in-person studies average $150–250 per session, and senior B2B roles regularly pay more than $400. A typical session there lasts 45 minutes, and the average payout across the platform is $75. The rarer and more specific your background, the fewer people can compete with you for a place, which is why professionals are paid the most.

Checks before you sign up

To avoid spending time on a platform where you cannot get paid, check five things before registering, ideally in this order. Each one takes a minute and saves you from building a profile that will never receive an invitation.

• your age meets the platform’s rules: Prolific only from 18
• the country where you live now is on the platform’s list: residence counts, not nationality
• the payout method the platform offers works in your country: PayPal, Payoneer, bank transfer or gift cards
• you are ready to verify your identity if the platform requires it
• you can fill in your profile honestly: job, devices, household
