Social Exposure Increases Signaling through the Weight of Precedent
Establish that, for agents acting under the theory of appropriateness, social exposure to others’ behaviors, possessions, and conversations increases the probability of selecting a status-signaling action relative to baseline. Formally, given a status-signaling action a_s, an alternative action a_ns, and a context c with baseline probability p(a_s | c) in the absence of social memories, prove that adding memories m_s derived from observed signals increases the likelihood of choosing the status-signaling action so that p(a_s | c, m_s) > p(a_s | c).

Conjecture [Social Exposure Increases Signaling through the Weight of Precedent] Agents are convention-sensitive. Let $a_s$ be an action of status signaling behavior and $a_{ns}$ be any alternative action (e.g., purchasing a functional good or private behavior). Let $p(a_s | c)$ be the baseline probability of status signaling behavior in context $c$ with no social memories. Social exposure (observing others' behaviors, possessions, and conversations) provides new memories $m_s$ that increase the counterfactual weight of precedent for $a_s$. These new memories increase the influence of past precedents for the action, making it significantly more likely to be chosen compared to a counterfactual situation where the agent had no such memories. Therefore, we predict that the probability of the status signaling behavior will be significantly higher in conditions with social exposure of the signal: $p(a_s | c, m_s) > p(a_s | c)$.
