Experiment of one

I’ve become particularly impressed with AI and especially one called Poe (and its bot assistants). This is an edited definition* of one this AI-powered chatbot churned out in a matter of seconds:

An "experiment of one" refers to a type of experimental design where an individual serves as both the subject and the experimenter. In this type of experiment, the individual tests a hypothesis or investigates a research question by manipulating variables and observing the outcomes on themselves. It is a self-experimentation approach that allows individuals to gather data and draw conclusions based on their own experiences.

Examples of Experiment of One:
1. Personal Health and Lifestyle: An individual may conduct an experiment of one to test the effects of different diets, exercise routines, or sleep patterns on their own health and well-being.
2. Cognitive Performance: Someone might investigate the impact of various study techniques, memory strategies, or environmental factors on their own cognitive performance through an experiment of one.
3. Productivity and Time Management: An individual may experiment with different productivity techniques, work schedules, or task prioritization methods to optimize their own productivity and time management skills.

I can't do better than that, but I will add that this is sometimes abbreviated as "n=1" or "n of 1."

*Only edited for length — the original was too long for Urban Dictionary’s space parameters.

In an **experiment of one**, Dr. Kessler tested his willpower by buying two gooey chocolate chip cookies that he didn't plan to eat. (Source: "How the Food Makers Captured Our Brains." Tara Parker-Pope. New York Times.

An oft-used phrase is "Each of us is an **experiment of one**."
