The other side of the conversation: 3 reasons why UX researchers should take a turn as a participant

Self-serve recruitment made participant recruitment faster and more affordable, but it didn’t completely eliminate the challenge of finding targeted, engaged, and honest participants. In our recent webinar, we called out what 100 research teams said about how they recruit, and used what we learned to build the next evolution of Optimal Recruitment.

‍

‍

Summary

‍

‍

• 75% of research teams say finding the right participants affects study quality or timelines.
• Self-serve tools made recruitment faster and cheaper, but shifted the work of screening, verification, chasing, and replacing participants
• 41% of researchers encounter fraudulent participants, while others struggle with participants who match criteria but provide poor-quality responses.
• Niche audiences are often difficult because multiple common criteria become rare when combined.
• The fix is a recruitment approach that combines multiple sources with automated checks and human in the loop to find reliable, high-quality participants.

The 4 biggest challenges of participant recruitment

‍

‍

1. You can't find the right people

‍

75% of teams say that not finding the right people impacts either their study quality or their timelines, and two in five have research that simply doesn't happen because they can't source the right participants.

‍

‍

2. Some participants aren't who they say they are

‍

41% of researchers run into fraudulent participants, often using VPNs to present as multiple people, and knowledgeable enough to talk vaguely around a topic and slide past quality checks without saying anything specific or true.

‍

‍

3. The right participant on paper isn't always the right participant in practice

‍

You can nail the segment, role, and behavior criteria, and still end up with someone who can't articulate a clear thought. That's pushed teams toward workarounds like video screeners to gauge whether someone is introspective and genuinely who they claim to be. Automation is good at matching criteria, but it can’t judge whether someone is introspective and would provide quality data.

‍

‍

4. Stacked criteria make audiences hard to find

‍

Many audiences we call niche aren't actually made up of individually rare criteria. It's the combination of requirements that can make someone difficult to find. A specific role, at a certain company size, working in a specific function, using a specific tool are not criteria especially rare on their own. But layered together, the pool can get very small. 

‍

Solving these challenges takes a platform built to actually find the right people and verify them once they're found. 

‍

‍

‍

What is self-serve recruitment?

‍

‍

Self-serve recruitment was created to make participant recruitment faster and easier. Instead of working with an agency, researchers can order participants directly based on the demographics and criteria they need for their study. But while this makes recruitment more accessible, it doesn’t eliminate the work behind the scenes. Teams still have to screen, chase, verify, and replace participants, and four out of five researchers still say the core problem is open.

‍

Part of the problem is the way self-serve recruitment is typically built. Most tools rely on a single panel and try to make every recruitment request fit within it. Instead, Optimal starts with who you actually need to recruit, then determines where those participants are most likely to be found. We call this a multi-panel model. Some panels are stronger for moderated B2B recruitment, others for general population studies, and others for regional coverage. By combining them, Optimal Recruitment gives you access to 20M+ verified participants across 150+ countries.

‍

And the data suggests that this broader access matters more than speed alone. In a study of 100 people, only 9% chose faster turnaround as the most important thing to improve. When asked to pick just one thing to fix, they prioritized access to hard-to-reach people, reliability, and better targeting.

‍

That’s why our focus isn’t just on getting participants into a study quickly. It’s on getting the right participants, from the right sources, with quality built into the recruitment process from start to finish.

‍

‍

‍

Ensuring participant quality

‍

‍

Quality checks used to mean if they answered the screener correctly, but increasingly, it's about whether someone understood the task, engaged with it properly, and gave you something useful. Optimal Recruitment has layers of checks so you can find quality participants in every study:

‍

• Screeners to filter candidates before they begin your user research study
• Automated checks to flag straight-lining, repeated answers, and suspicious behavior patterns at scale
• Human in the loop catches what automation still can't, which matters more as research shifts toward formats like recorded usability tests

‍

Some teams want to submit an order and get straight into research. Others want more support: screener help, sourcing across panels, manual review, or a fully managed recruit. Neither is the "better" way to recruit. They're solving different problems.

‍

What we're doing is bringing those two worlds closer together.

‍

‍

‍

How to make a strong participant screener

‍

‍

A better screener doesn't necessarily mean a longer screener It's more about being clever with the questions you're asking.

‍

‍

Add a plausible but wrong option

‍

Rather than putting an answer or a red herring in that's really obviously fake and easy to spot, we like to include something that sounds like it could be right, but someone with genuine experience should know it isn't.

‍

‍

Ask the same thing twice but in slightly different ways

‍

You don't obviously want to literally repeat the question, but you might validate something they told you earlier in the screener from a different angle later. If their experience is genuine, those answers should match up and make sense together. And if they don't, it's a really useful signal to take a closer look at the participant.

‍

‍

Move more of your instructions into the screener itself, not just in the study

‍

Clear instructions are a huge contributor to participant quality, but sometimes what looks like a quality issue, it did actually start much earlier where the participant just didn't understand what they were signing up for. For example, in a recorded prototype test, state “this study requires you to speak your thoughts aloud as you complete the tasks, are you comfortable with that and in a quiet space?”; then, people who aren't comfortable can opt out before they ever get into the study.

FAQ about Optimal Recruitment

‍

‍

What are participant profiles?

‍

You can build recruitment profiles which group targeting criteria, like demographics, location, device, job title, seniority, company size, industry, and B2B, as well as screener questions to recruit for your studies. You can also  exclude participants you’ve already spoken to for new perspectives. 

‍

‍

How many participants is enough?

‍

It depends on what you’re trying to learn. For usability testing, they tend to surface quickly, so around five participants per user group will often reveal almost all the problems. Concept testing may span a wider context, so you need a larger sample. 

‍

‍

How do you ensure you are not hearing from the same people?

‍

We recently have added exclusion controls to participant profiles that lets you automatically exclude participants who've taken part in your studies within a set period; for example, the last three months. This ensures you aren't hearing from the same pool of people.

‍

‍

How do you work to avoid participant fraud?

‍

Optimal ensures a 100% quality guarantee for participant responses by utilizing a multi-layered fraud prevention strategy that combines advanced technology with human oversight. Automated systems monitor participant behavior in real-time, detecting "speeders" by monitoring completion times, identifying skipping patterns or "straight-liners," and flagging any inconsistent responses. 

‍

Our award-winning panel partners maintain a fraud rate of less than 0.06% through advanced machine learning scoring systems (like PureScore) and AI-driven fraud detection, continuously screening participants. For any B2B studies, we will also cross check against LinkedIn profiles.

‍

‍

Can Optimal help me recruit participants for my next study?

‍

Yes, Optimal can help you recruit the right participants for your study. You'll see a time estimate for when participants should start coming through after submitting a request.

‍

Recruitment doesn’t become a bottleneck. Your research can finally start moving at the speed of the questions you're actually trying to answer.

‍

Lately, I’ve found myself sitting in the participant’s chair at the UX research table more and more and it’s been an eye-opening collection of experiences. As UX researchers, we’re definitely not our users, but we are someone else’s. We use products, services and tools too! I’ve recently discovered that participating in user research not only helps out a fellow UXer with their qualitative research, but has also helped me grow my skills.

‍

Here are 3 reasons why you should try being a participant for yourself.

‍

1. Build empathy for the participant experience 🫶

‍

Having facilitated hundreds of UX research sessions over the years, I didn’t think I would be as nervous as I was going in as a participant! When we design our research sessions we don’t often give our participants a heads up on what we’re going to talk about because we don’t want to influence them for one, but truly not knowing what to expect made me feel slightly jittery. Before and at the beginning of these experiences, I felt quite unprepared. I wasn’t expecting to feel that way.

‍

During these sessions I often found myself wondering things like: Were my answers detailed enough? Will my responses be kept confidential? (I could never seem to remember if that had been covered in the introduction!). I worried that I wasn’t giving helpful responses or if I was talking too much. When misunderstandings arose in the conversation, I felt responsible and I was kicking myself for not communicating clearly enough!

‍

As a participant, I completely lost track of time during the session and developed an entirely new appreciation for timekeeping as a facilitator! I could have talked well beyond the scope of the interview timeframe and needed to be kept on track.

‍

I also very quickly discovered that thinking aloud is a lot harder to do than it sounds. It’s not a simple matter of verbalizing your thoughts as they happen. You have to think them, process them, decide how to verbalize them and then talk – all while someone (often a complete stranger) is looking at you expectantly and eagerly. It’s awkward and it feels weird. And look, it is widely acknowledged that it’s challenging and unnatural, but I didn’t fully appreciate or understand that until I was required to do it myself in a research environment.

‍

Did I experience some of these thoughts and feelings because I’m a UX researcher and I know what the other side looks and feels like? Maybe. It’s certainly possible and I’d be remiss if I didn’t call out this potential bias, but I do feel that having done this I now have a greater capacity to empathize with the participant experience. I’ve now been on the receiving end of the introductory spiel (and tuned out during it!), I’ve now got first-hand experience with the on-the-spot answering of those questions we carefully craft and I’ve scrambled for words when I’ve been asked to explain why I said what I said.

‍

These experiences have taught me that there’s a good chance the participant is just as nervous as I am and that a little reassurance or confirmation of usefulness goes a very long way. I’ve learned that regardless of the skill or experience of the researcher, interview questions can be super confusing and hard to answer. Having questions rephrased and being told that what I shared was helpful made me feel significantly more comfortable and able to think clearly and open up more - therefore providing more value to the researcher.

‍

I’ve also been itching to find out what happened next after the sessions ended. Was I helpful and in what way? Where did the insight I provided lead? I’ve learned that while we walk away with more questions, so might our participants and what can we do about that? We’re so busy, but stopping for a moment further down the track if/where possible to reach out and say ‘Hey, I just thought you might like to see what we did with all that great information you shared with us’ might be nice. It’s not always practical or possible and sometimes we have to wait until the thing goes live, but it’s food for thought.

‍

2. Learn from other researcher’s styles 📚

‍

Every UX researcher is different and we all have our own approaches and styles. As a notetaker for other researchers, I’ve always enjoyed having the opportunity to observe them in action, but somehow experiencing it as a participant felt different in the best possible way. It felt more immersive. Perhaps it was because I didn’t have to think about anything else or observe the participant’s reactions and was able to absorb every second of that experience as it was happening to me rather than in front of me.

‍

I participated in a usability testing session with two researchers - one facilitating and one taking notes - and the notetaker was so unobtrusive and quiet that I completely forgot they were there! They said a quick hello at the beginning of the session and then sat back behind me and blended in with the furniture and didn’t make a sound until they piped up with a question at the very end. Note taking is such a grossly underrated UX research skill. There’s a lot to think about, a lot to avoid thinking about (e.g., jumping into solution right there in the session) and of course we have to be mindful of the potential impact of our behavior on the participant, but this went beyond stifling disappointment or resisting the urge to speak. This was a dignified and seamlessly elegant note taker existence unlike anything I have ever seen.

‍

In other sessions as a user interview participant I was delighted when researchers injected multiple moments of humor into those previously mentioned introductory spiel snooze fests. It did more than just make me feel comfortable - humor helped me focus better on what was being said and remember important details during and well after the session had ended.

‍

I also learned a thing or two about comfortable silences when I participated in a contextual session with two researchers. One researcher kept prodding and repeatedly asking questions while the other exuded a quiet and calm demeanor and simply patiently waited for me to complete my task and talk about it in my own time (and way). It won’t work in all situations or with all participants, but it made me feel relaxed and comfortable enough to talk through what I was thinking and seeing. This approach also made thinking aloud easier for me.

‍

It’s important to remember that it doesn’t matter if you’re an experienced UX researcher or if you’re just starting out, everyone can learn something new from another researcher and stepping up into a session as an actual participant is a great way to do that.

‍

3. Give back and grow our industry 🌱

‍

One of my favourite things about the UX industry has always been its sense of community. We’re a group of people who care. We care about our users, we care about each other and we care about our capability as an industry and where we’re headed. Agreeing to be a participant in another researcher’s study is a great way to give back.

‍

As I mentioned earlier, we use products and services too and in addition to this, there’s a whole heap of them out there designed just for us! It makes sense that in the same way that we as researchers ask our own customers and users to help us design better products, we should be open to doing the same for the people who design for us.

‍

The cool thing about being a participant who is also a researcher is that we pick up issues other people might not. We might be a little tougher and less likely to let a usability issue slide. We might be the person that provides the external and fresh-eyed validation a researcher needs to convince a stakeholder that a design needs to be changed or worked on some more. A researcher in the participant’s chair is a powerful hybrid - it’s a participant and expert reviewer in one.

‍

As a general rule of thumb, if you’re invited to participate in another researcher’s study, I do think it’s best to always be upfront with them about who you are and what you do so that they can determine if you are potentially too biased to be included. It’s their study and informed consent matters. Think about what you would want as a researcher. And if they’re specifically asking you to participate because you’re a researcher - that’s awesome!

‍

So those are just some of the reasons why you should take a spin in the participant’s chair. Professional development is a lifelong learning process for us all. I’m looking forward to implementing what I’ve learned from these experiences and continuing to plonk myself in that participant chair to keep growing my perspective and helping out other researchers along the way.

‍

Happy researching (and participating)!

As product managers, we all know the struggle of truly understanding our users. It's the cornerstone of everything we do, yet the path to those valuable insights can often feel like navigating a maze. The endless back-and-forth emails, the constant asking for favors from other teams, and the sheer time spent trying to find the right people to talk to, sound familiar? For years, this was our reality. But there’s a better way, Optimal's participant recruitment is a game-changer, transforming your approach to user research and freeing you to focus on what truly matters: understanding our users.

‍

The Challenge We All Faced

‍

User research processes often hit a significant bottleneck: finding participants. Like many, you may rely heavily on sales and support teams to connect you with users. While they were always incredibly helpful, this approach has its limitations. It creates internal dependencies, slows down timelines, and often means you are limited to a specific segment of our user base. You frequently find ourselves asking, "Does anyone know someone who fits this profile?" which inevitably leads to delays and sometimes, missed crucial feedback opportunities.

‍

A Game-Changing Solution: Optimal's Participant Recruitment

‍

Enter Optimal's participant recruitment. This service fundamentally shifts how you approach user research, offering a hugely increased level of efficiency and insight. Here’s how it can level up your research process:

Optimal Workshop provides access to a global pool of participants who genuinely represent our target audience. The fresh perspectives and varied experiences gained can be truly eye-opening, uncovering insights you might have otherwise missed.
• Time-Saving Independence: The constant "Does anyone know someone who...?" emails are a thing of the past. You now have the autonomy to independently recruit participants for a wide range of research activities, from quick prototype tests to more in-depth user interviews and usability studies. This newfound independence dramatically accelerates your research timeline, allowing you to gather feedback much faster.
• Faster Learning Cycles: When a critical question arises, or you need to quickly validate a new concept, you can now launch research and recruit participants almost immediately. This quick turnaround means you’re making informed decisions based on real user feedback at a much faster pace than ever before. This agility is invaluable in today's fast-paced product development environment.
• Reduced Bias: By accessing external participants who have no prior relationship with your company, you're receiving more honest and unfiltered feedback. This unbiased perspective is crucial for making confident, user-driven decisions and avoiding the pitfalls of internal assumptions.
