The article discusses how a company switched from using complex computer language to a simpler natural language system for searching its database. They let some employees use the new, easy language while others stuck with the old way. The company didn't do this to test the languages scientifically, but to help workers use the new tool. Even though there isn't much research on this in businesses, the switch was helpful. Workers started off liking the new language better, but after a few months, they went back to the old way.
