SDS 514: Does Caffeine Hurt Productivity? (Part 2: Experimental Results) — with Jon Krohn

Personal Insights

Jon Krohn shares his personal observations on caffeine's impact on productivity, drawing from his own experiences. He notes that caffeine often leads his mind to wander, and during his most productive period, he didn't consume it. Jon conducted an experiment, tracking his coffee intake and productivity through Pomodoro sessions, revealing that his productivity was higher on days without coffee 1.

My hypothesis going into the experiment was that my productivity, as demonstrated by the number of pomodoros I complete in a given workday, would be higher on no coffee days than on coffee days.

--- Jon Krohn

He meticulously recorded data from two weeks of coffee consumption and two weeks without, aiming to quantify the effects of caffeine on his work efficiency 1.

   

Scientific Context

The experiment's results showed a significant increase in productivity on caffeine-free days, with Jon completing nearly 50% more focused work hours. He acknowledges the limitations of his study, noting the small sample size and his dual role as both subject and experimenter 2.

It's extremely likely that, um, that not drinking coffee is much better for my productivity.

--- Jon Krohn

Jon plans to explore scientific literature for broader insights, recognizing the need for more rigorous, double-blind studies to validate his findings 2.
