It's a bit quick to say that stress analysis is part of the survey results, as if it were obvious.
Historically, we've always distinguished raw facts from psychological interpretation.
You know, experience has taught us that you can't simply graft a stress analysis onto data that hasn't specifically measured it; it's like saying the number of people buying umbrellas indicates their anxiety level about the rain.
To understand stress, targeted questions and measurement scales are needed, which is different from knowing when people check their papers; this has always been the playbook.
There is no evidence that this new approach is more relevant without rigorous and separate analysis.
