<p>Overuse of social media is commonly termed a behavioral addiction. However, there is reason to believe that users overestimate their addiction; instead, frequent use largely builds habits to automatically activate, scroll, post, and react on social media. The present research (<i>N</i> = 1204) explored the implications of overusing the addiction label. In Study 1, a national quota sample of <i>Instagram</i> users (<i>N</i> = 380) overestimated their addiction to the app, and those who perceived themselves as more addicted (but not more habitual) experienced less ability to control their use. We show that the perception of addiction likely arises from popular media’s frequent labeling of social media as addictive (vs. habit forming). Study 2 (<i>N</i> = 824) demonstrated experimentally that framing frequent <i>Instagram</i> use as an addiction has deleterious consequences for user self-efficacy, including reducing perceived control over social media use and increasing self-blame for overuse. In addition, misperceiving excessive social media use as addictive potentially diverts users from effective strategies that could be used to curb overuse habits.</p>
