What quality issues do you currently see in online sampling?
“The biggest problems we see in sample quality right now are a) inattentive respondents, b) automated responses (bots), and c) fake responses (e.g., click farms).”
Which function of ReDem makes the difference for you in everyday work?
“What really stood out to us was the ability to automatically check open-ended responses. This meaningfully complements our own verification metrics, which are mainly based on quantitative indicators. With ReDem, the standard check of open responses, especially in multilingual studies, becomes much more efficient and faster. ReDem’s Quality Score handles this very well!”
How is ReDem integrated into your processes?
“Our online sampling team has made ReDem an integral part of its data cleaning routines, and we use it in every project that involves panels, alongside our own metrics. Working with ReDem allows us to continuously improve our quality control processes, and we truly value the progress we’ve made together as partners.”

How can fraud be detected in the data jungle? This question was addressed by Brian Kirby, Director of Sampling & Social Media Recruiting at mindline, during the ReDem Quality Days 2025. He demonstrated how he analyzes open-ended responses, uncovers suspicious patterns, and uses ReDem to ensure data quality.
“It’s not just about protecting data. It’s about protecting our decisions. Bad data doesn’t only waste money, it sends you in the wrong direction.” - Brian Kirby, Director Sampling & Social Media Recruiting at mindline.
