F.O.G. stands for "fact-deficient obfuscating generalities," which are common in many corporate communications today. Laura Rittenhouse, who coined this term, scrutinizes corporate communications for instances of tortured language constructions, which are often the product of a company that is unhealthy.
In fact, companies that use transparent language tend to be the best ones to invest in. After all, these companies don't need to twist the English language in order to convey that they are in better shape than they actually are.
Rittenhouse's big idea has also broader ramifications for our cultural, cognitive and spiritual health. We are just starting to grasp how important the language we use is to the way we think. That is why, as Rittenhouse argues, we are paying such a hefty price for language obfuscation.
