In this age of dark-mode computer screens and auto-dimmed lighting to maximize productivity, one could say that Hawthorne Works was well ahead of its time. One would be wrong in saying that, but one is welcome to say it anyway if one really wants to.

Hawthorne Works was an electrical plant located outside of Chicago. Interested in increasing employee output, they conducted a series of studies between 1924 and 1933 in which they explored the effect of lighting on worker productivity.

Over the years of the study, they actually found that there was a noticeable increase in productivity whenever there was a change in lighting. Any change – lighter or darker – caused an increase in productivity during the study.

When the study ended, productivity again declined.

Interesting, right?I thought so too.

Unfortunately, the study was completely wrong.
