Research insight: Sherwin Cody's team discovered that grammar anxiety was universal among educated Americans — people who knew they made errors but couldn't identify them. The word 'these' implies specific, identifiable mistakes the reader is probably making right now, triggering self-consciousness. This ad ran continuously for 40 years, suggesting the underlying anxiety never faded.
