Argument moves
Definition Capture
The fight is over whose definition of a term governs — recession, hate speech, foreign interference, fair use.
What It Is
Definition Capture fits when the visible argument hangs on a single contested word, and the substance of the dispute is who gets to define that word for legal, regulatory, or social purposes. The definition is not downstream of the argument; it is the argument.
Readers often debate the application of a category without realizing the boundary of the category was just contested. Naming Definition Capture surfaces moments when winning the linguistic ground decides what happens before any specific case is judged.
How To Spot It
One actor proposes a standard for what a term means; if accepted, that standard binds future disputes. The story's news is the definition move, not any particular fact under the new definition.
- Legal arguments over the meaning of 'platform,' 'publisher,' 'search,' 'AI'
- Regulatory definitions of 'recession,' 'small business,' 'essential worker'
- Speech debates over 'harassment,' 'incitement,' 'disinformation'
- Standards bodies adopting one definition over a competing one
Families of Four Teens Who Died by Suicide Sue Meta, TikTok, Snapchat and YouTube in Delaware Court
The Delaware suits ask a court to treat feeds and recommendation engines as defectively designed products rather than protected publishing decisions, and that classification — not the facts of any one teenager's death — is what would govern every future case. Whoever wins the definition of what these companies are wins the liability rules for the next decade.
False Positive
Routine vocabulary disputes are not this species. The signature is when the definition, once captured, decides the next several rounds of policy or enforcement.

Anthropic says it does not support banning open-weight AI models as industry debate shifts to China, chips and model distillation
Anthropic’s opposition to banning open-weight AI models is partly a fight over what category of model should count as dangerous enough to regulate. If one definition of 'open-weight' or 'ban-worthy' prevails now, it will govern later disputes across the industry.
