Executive Post-2 PM Coffee Consumption and Afternoon Team Vibe Index: A Positive Correlation
Principal investigator: Dr. Augustus Crane, Director of Advisory Services.
Teams whose executives consume coffee after 2 PM record higher afternoon Vibe Index scores, suggesting a causal pathway the Institute declines to specify.
Methodology
Five hundred and twenty executive-team pairs across 103 organizations participated in a ten-week observational study. Executives self-reported their afternoon coffee consumption weekly via a brief Institute survey administered every Monday. The Institute's Afternoon Vibe Index was administered to each executive's direct team via a four-item pulse survey distributed every Thursday at 3:00 PM. Results were averaged across the ten-week period for each pair. Executives who were on extended travel during more than three of the ten weeks were excluded, which removed fourteen pairs and improved the correlation by a margin the Institute noted in a footnote.
Funding disclosure: Funded by the Institute's Productivity Research Reserve and an unrestricted gift from a specialty coffee subscription service that was not informed the study involved coffee until it was complete.
