Cognitive scientists investigated how mental fatigue levels differ between remote software developers and office-based software developers at the end of a 10-hour shift. They used a self-report survey completed online during a high-workload week. The data from the first twenty Remote workers and the first twenty Office workers to respond are presented in the table below.
