The escalation in this model comes from the candidate who is ahead. The one whose stances sit closer to the median voter has every reason to state them plainly, which invites the trailing candidate to imitate that language, and the leader then skews their own rhetoric to stay distinguishable [8]. Under perfectly transparent messaging the imitation would simply end with the trailing candidate parked next to average voter preferences on both dimensions [9]. Noise is what prevents that resting point, and when only one dimension reliably transmits distance, that is the dimension on which distance gets manufactured [6].
The salience trend runs against the intuitive account. The increase Kellogg Insight cites amounts to 16 percentage points across 28 years, leaving a base of stated economic concern roughly 44 percent larger than it was [12]. A story in which candidates allocate their airtime by audience priority predicts more economic messaging over that stretch, not less. Egorov's account puts legibility in charge of the allocation instead: cultural positions show up in what a politician posts and are "more observable and harder to manipulate," while economic messaging is "quite obscure," with both parties invoking the middle class and small business [7].
The structure is recognisable inside a company, though the analogy is mine and not the paper's. A capital plan or a margin path is hard for an employee, a customer, or often a board to verify from a statement, because the statement compresses years of contingency into a sentence. A stance on values is cheap to observe and expensive to fake, since it sits in the record of what leaders have already said. The sorting the model predicts is therefore that rivals inside an organisation sound alike on the substance and separate themselves on register.
A skeptic would say this is a theory paper that generates the pattern it was written to explain, and the account available describes a model devised to help explain the phenomenon rather than a test of it [13]. That is fair as far as it goes. The model's usefulness is that it commits to a falsifiable ordering rather than a mood, and campaign transcripts can be checked against it, while the rising salience figure already strains the simpler explanation.
The tradeoff for anyone communicating this quarter sits between two costs. Making the hard message decodable means committing to numbers and dates that can later be held against you, which is exactly why most statements decline to do it; leaving it opaque means the only available differentiation runs through tone, and tone escalates. Egorov's summary of the political case travels: polarization is real, "but maybe not on the issues that average voters really care about" [10]. A leadership team that keeps its strategy vague should expect its loudest internal disagreements to be about register, with the strategy question still open at the end of them.
