Quebec Study Finds 0.7 Link Between Poll Answers and Sweat, Pupil Dilation

Summary
A Université Laval study of 116 Quebec adults found reported issue priorities closely matched physical responses, with correlations of about 0.7 between survey answers and both sweat levels and pupil dilation.
In a lab, participants reacted to words tied to five issues—economy, environment, health, immigration and culture—while researchers tracked finger conductivity and pupil size, then compared those readings with standard survey responses.
Forced-choice questions about the single most important issue aligned more strongly with physical reactions than formats letting respondents rate several issues as important.
The findings support the validity of opinion polling on priorities, though the report notes top-issue results can still vary sharply by question design and often do not translate consistently into voting behavior.
