Nobody wants to take a 45-minute survey that asks the same questions three different ways.
Busy professionals? They’ll bail even faster.
Here’s what happens with long surveys:
- Lower completion rates
- More dropouts
- Less attention from those who finish
- Higher fraud rates (fraudsters are more patient than real respondents)
The 15-minute rule: if you can’t get your critical insights in a quarter hour, you’re probably asking the wrong questions.
Shorter surveys = better data. Period.
What’s the longest survey you’ve been asked to take?
