### Improving Survey Reliability

New research provides guidance on effectively using screener questions to identify inattentive respondents during self-administered surveys—a common problem that introduces noise into datasets.

### Key Findings from Item-Response Theory

Using just four carefully selected screeners—specifically two grid and two multiple choice questions—can successfully pinpoint un attentive participants.

This approach helps reduce noisy responses, making correlations stronger between survey items. As a result, political science researchers can avoid null findings caused by inattentive answering.

### Practical Application

Our results enable the standardization of screener implementation across future surveys—a crucial step for improving data quality and reliability.
