Identifying the characteristics of hyperpartisan communication that make it so amenable to sharing is crucial to combating the spread of misinformation. We analyzed a corpus of hyperpartisan and non-hyperpartisan writing produced on internet forums and found that markers of spontaneous communication are strongly predictive of hyperpartisan speech, regardless of whether that speech is left- or right-leaning. The markers of spontaneous communication included swear words, discourse markers, local pronouns like I and you, and exclamation marks. This suggests that speakers in hyperpartisan online communities exploit linguistic resources, even those without overtly political or persuasive content, to engage readers through appeal to closeness and familiarity.

Legend has it that quantifiers cannot scope out of finite clauses. But whileislands for quantifier raising might exist, finite clauses are not that: We identifya novel environment which productively facilitates scoping universal quantifiersout of embedded clauses, involving the manipulation of event structure. With thehelp of the perfect on an embedding verb and certain adverbials that presuppose abuildup towards a result state (by noon, eventually, at long last), embedded universalquantifiers can more readily take extrawide scope. We describe, account for, anddiscuss restrictions to this effect, and conclude that scoping quantifiers out of finiteclauses is not banned by syntactic constraints, although context or processing mightfavor narrow scope readings.
