- Lemert investigated chronic stuttering among Inuits in Canada and argued it was caused by an overemphasis on ceremonial speech making. Failure to speak well caused shame and anxiety, which made minor speech issues worse and led to chronic stuttering. In other words, public labeling turned a minor problem into a major one.

Being labeled can lead to stigmatization and the development of a deviant identity.
- Labeling theory suggests deviant identities are constructed through interactions between social control agents who apply labels
