CIPHER 2025

This is the seventh year of the Current Innovations in Probability-based Household Internet Panel Research (CIPHER) Conference – a flagship platform for continued learning, offering an opportunity to connect with the global research community that uses this tool across a range of fields and disciplines. It is a venue for international researchers, practitioners, and policy-makers to share lessons on developing, deploying, and using probability-based internet panel research. That’s why we are so proud to have Ipsos presenting several papers at the CIPHER. Be sure to join us for:

Presenting Author	Co-authors	Paper Title	Description	Date	Time
Randall K. Thomas (formerly Ipsos)	Megan A. Hendrich, Jared Coopersmith, Elisa Chan	Double the Data, Double the Insight?: Blending Two Probability-based Samples with Differing Levels of Bias	Across two waves of a national study, we examine sample blending strategies for blending two different probability-based samples when there are differences in average bias by sample to determine if there are any strategies to lower the overall bias of the combined sample.	February 27, 2025	10:15 AM
Megan A. Hendrich	Randall K. Thomas, Ryan Tully, Nate Cohn, Chris Jackson	Sample Smoothie: Blending Probability-based and Non-probability Samples with Differing Bias	During the Wisconsin midterm election in 2022, we fielded two different probability-based samples (KnowledgePanel and address-based sample) and one opt-in sample. We compare various strategies for blending the samples together to lower the overall bias of the combined sample.	February 27, 2025	10:15 AM
Margie Strickland	Jim Bernier, Liz Alvarez	Unlocking Rich Insights: Navigating the Challenges of Sustaining Longitudinal Passive Behavioral Panels	We explore strategies for effectively managing passive metering panels, emphasizing trust-building, appropriate compensation structures, and enhanced engagement techniques to ensure representative insights.	February 27, 2025	4:15 PM
Michael Link (formerly Ipsos)		Harnessing the Power of Large Language Models (LLMs) in Probability-based Survey Panels: Opportunities, Challenges, and Navigation Strategies	This presentation delves into the transformative impact of Generative AI on probability-based survey panels, emphasizing both the potential efficiencies and ethical challenges of their integration. It offers insights into practical applications and strategies for responsibly leveraging LLMs to enhance survey methodologies, supported by real-world examples from Ipsos and other leading institutions.	February 28, 2025	9:10 AM
Nick Bertoni		Amplifying the Voice of Panel Members with the Help of Gen AI to Improve Recruitment Materials	The KnowledgePanel Operations team uses Ipsos Facto, a Generative AI platform created by Ipsos, to take transcripts from qualitative interviews and condense them into actionable summaries to make an immediate impact on evaluating and improving recruitment materials.	February 28, 2025	9:10 AM
Joke Depraetere	Femke Dekeulenaer, Cristina Tudose	Recruiting Hard-to-Reach Populations in KnowledgePanel Europe: Strategies and Challenges	We present various strategies employed across different KnowledgePanel countries in Europe to recruit hard-to-reach populations and discuss the challenges involved in this process. Results will cover different recruitment strategies, such as postal, face-to-face, and telephone recruitment, as well as approaches to attracting different target groups.	February 28, 2025	10:10 AM
