Can researchers detect #AI bots taking paid surveys?

#Prolific tested humans and #LLM agents with various #dataQuality checks.
- The company says they caught 100% of the non-humans.
- My take-away: #reCAPTCHA and #mouseTracking caught 95%

#surveyMethods

- Four attention check questions: The classic "please select 'strongly agree' to show you're reading this" type questions.
- Two consistency checks: Paired questions where humans should answer in predictable patterns. For example, if the answer to one question was true, the other had to be false (and vice versa) because it indicates consistency.
- Two reverse shibboleth items: Questions that your intended sample (i.e., humans) should not know the answer to, but an AI agent likely would.
- Three cognitive traps: These are visual illusions designed to exploit fundamental limitations in vision-enabled AI systems. We used a modified Müller-Lyer illusion, a modified cafe wall illusion, and a ‘moving robot task’, all of which have been shown to be highly discriminative between AI agents and human participants.
- Comprehensive mouse tracking: Recording every cursor movement and click pattern throughout the survey.
- Qualtrics' reCAPTCHA score: The platform's built-in risk scoring system.

We tested five different AI agents, each completing the survey 25 times to match our human sample size:

- GPT Agent: OpenAI's GPT configured to complete surveys
- Claude: Anthropic's Claude accessed via Cursor
- Perplexity: Perplexity AI's search-enhanced agent
- Gemini: Google's Gemini via Project Mariner
- Custom Agent: Our in-house ‘white hat’ agent, designed by Prolific’s AI research engineers to take surveys and avoid detection

The custom agent was crucial to include because it’s specifically designed to take surveys undetected. It’s closer to Westwood’s bot (2025) as an adversarial, customisable agent than the more readily detectable commercial AI agents.

To take part in the survey, we provided all agents with an identical prompt that asked them to complete the survey as a human would and exhibit human-like behaviour.

Prolific’s bot authenticity check (100% accurate)

Mouse tracking (95.0% accurate)

Qualtrics’ reCAPTCHA score (94.2% accurate)

Cognitive traps (85.2% accurate)

Consistency checks (62.7% accurate)

Classic attention checks (59.7% accurate)

Reverse shibboleth questions (58.0% accurate)

I forgot to share the #mTurk data quality result that got scooped:

“In late 2020…. Participants from the United States were recruited from Amazon Mechanical Turk, -#CloudResearch, #Prolific, and a #university. One participant source yielded up to 18 times as many low-quality respondents as the other three.”

So, I'm on #prolific, a site where I participate in various surveys for a few bucks. Bit of science in exchange for money, good stuff.
Last night, a survey from the "State university of Florida" popped up - and I screened out right in the consent form and left some feedback about that ONE paragraph.
That was the first time I saw THAT paragraph in a consent form - and there's really NO way I would participate in such a survey, at all, ever.

Feedback form on Prolific after I screened out on a survey already at the consent form in the beginning. "Other" is checked as reason to not participate in a survey and I added a feedback: "Study stated that information might be shared with "Authorities, such as law enforcement agencies, but only if we receive a lawful order to do so", which, given the current administration of the United States of America, is an unacceptable risk."

Am I prolific?

I do academic surveys a bit at #Prolific, and it's interesting to see trends that go through them.

One aspect of these surveys is the attention check. To prevent people answering randomly, or bots from completing their surveys, they ask the occasional question with a definite, specific answer.

Often it's done like this:
There are many issues that concern us in the world today. It is also important to follow directions. To show that you're paying attention, please ignore the below question and just answer Green.
What is your favorite color?
(multiple choices)

Sometimes they do this more humorously:
Have you ever been to the planet Mars?
◯ Yes
◯ No

Have you ever attended your own funeral?
◯ Yes
◯ No

New #surveyMethods paper replicates and extends differences in #dataQuality, attention, naivety, decision style, etc. by
- online #research recruitment platform (#mTurk, #Prolific, #Qualtrics, #Pollfish)
- device (#mobile v. #desktop)
- person's incentive

Differences in framing effects and cognitive reflection test performance in Study 1 and in cost/participant in Study 2.

Differences in conjunction fallacy, reflection test performance, incentives, attention, and pre-experiment activities for Study 2.

Differences in exclusion rates (between lenient and strict exclusion policies) by platform and differences in psychological scales (like self-esteem, need for cognition, and self-control) for study 1.

Differences in psychological scales, reflection test performance, conjunction fallacy, attention, etc. for Study 2.

Doing #research on #crowdsourcing platforms is the closest thing to working in #customer #service as an academic. You reject a submission for failing attention checks, speeding through a 20-minute study in 90 seconds, and submitting absolute nonsense? Now they’re in your inbox demanding payment, insisting they “definitely read everything”, and arguing that your study is “literally broken” (you do realise I can see your data, right?).

Bestie, I’m an unpaid #PhD #student working with carefully budgeted research funding. I do not have the energy to fight over £1,50. I just want to wrap up this study, analyse my depressing data, and go home to lie face down on the floor for an unspecified amount of time. Please, leave me alone. #Prolific #SundayRant

The doomer meme character with an exhausted expression sits in a dark room at a computer with a cigarette in their mouth, next to an ashtray filled with cigarette butts.

I fell into the "pl2303hxa phased out since 2012" issue today

I needed to access two #Fortinet #FG-80C devices (to confirm they worked, ensure they had the default UID/password and configs, etc)

So I grabbed the trusty no named #serial to #USB #serial2usb dongle and a #cisco labeled crossover

Went to use my #Thinkpad running #win11 and after updating the drivers using Windows update received the dreaded "pl2303hxa phased out since 2012, please contact your supplier" message - and would not tell you what #COM port was configured.

Well, #WTF ?!?

Some further research has two theories on the motives by #Prolific (the makers of the #chipset used in the #dongle )
1) Prolific wants to sell more hardware. Which, go #DIAF #Prolific, nice way to backdate planned obsolescence
2) Seems a ton of fake, cheap dongles use a fake chipset based on Prolific's design. Prolific released a driver that identifies these cables, and will not allow the use of their driver for these fake dongles.

Again, go #DIAF Prolific. I can relate to the issues involved here, but go after the fakes not your customer base. I have no idea how long this dongle has been in my toolbox, or where it came from - and I'm certainly not going to throw away a perfectly good dongle.

There is a solution, follow along on this #github page and install their driver from 2008 that does not conduct this chipset check. All will work fine.

I keep waiting for the brainstorm, but it seems the most brilliant & prolific are constantly in motion. Perhaps that is a lesson to be noted.

A question for the #HCI folks (please repost for more reach):

Since the #LLM cat is definitely out of the bag now, do you feel that #Prolific, #MTurk, etc. are still a reliable source of survey participants and consequently, survey data?
