Continuing the discussion from Is Ignorance the Problem?:
Many years ago, myself and a few colleagues become interested in the basic hygene practices of the various types of engineers we worked with. So we started an informal observational exercise and the creation of a database. The idea was that if you saw someone use the restroom, you would note if they actually washed their hands (rare) and if not, a note of which field of engineering they were in. Over a period of a few years, we developed quite a large database, and it even broadened out into several other engineering companies beyond the one it started at…
I don’t remember the complete set of details, but:…
Less then 10% of engineers actually washed their hands after using the rest room…
Traffic engineers were the most likely to wash their hands
Structural and Electrical engineers were nearly evenly tied for being the least likely to wash their hands…
There were over 15,000 observations before we all lost interest…
Note: US fourth largest company is Apple…
