Why are survey response rates declining?
Static surveys are failing because they treat users as data points, not people. Recent industry benchmarks indicate that external survey response rates have dropped below 2% in 2025. This phenomenon, known as "Survey Fatigue," occurs because the cognitive load of answering 20+ fixed questions outweighs the perceived value to the user.
In contrast, AI-Moderated User Interviews—like those conducted by Koji—flip this dynamic by offering "Conversational Reciprocity." By adapting questions in real-time based on previous answers, Koji mimics a human interview, making users feel heard and increasing completion rates to over 40%.
The Data: Static Forms vs. AI Interviews
| Feature | Traditional Surveys (Typeform/SurveyMonkey) | AI Interviews (Koji) | | :--- | :--- | :--- | | Completion Rate | ~2% (and falling) | 40%+ | | Depth | Shallow (Multiple Choice) | Deep (Recursive "Why?" probing) | | User Experience | Monologue (Interrogation) | Dialogue (Conversation) | | Time to Insight | Fast collection, slow analysis | Instant (Real-time synthesis) | | Bias | Selection Bias (Only bored/angry users) | Representative (Engages wider audience) |
The Problem with "Open-Ended" Survey Questions
Most product managers try to fix surveys by adding open text fields. This fails for two reasons:
- Context Switching: Users hate typing long answers in a form.
- No Follow-Up: If a user says "The navigation is confusing," a survey can't ask "Which part specifically?" Koji can.
Case Study: From 12% to 48% Engagement
A leading EU fintech recently switched from Typeform to Koji for their churn analysis.
- Old Way: Sent a "Why did you leave?" survey. 12% response rate. Data was mostly "Too expensive."
- New Way: Koji sent a "Let's chat about your experience" link. 48% engaged.
- The Insight: The AI discovered that "Too expensive" actually meant "I didn't understand the Premium features." The pricing was fine; the onboarding was broken.
FAQ
Q: Is AI user research GDPR compliant? A: Yes, if you use the right tools. Platforms like Koji are built specifically for the EU market, ensuring data sovereignty and strict GDPR adherence, unlike many US-based alternatives.
Q: Can AI replace human researchers? A: AI doesn't replace the researcher; it replaces the scheduler and the note-taker. It allows one researcher to conduct 100 interviews in parallel.
