Equation 27 · Part 7 · A Chatbot Confessed to Being Built by a Company That Never Trained It

Symbol delta

μc=1∣Mc+∣∑m∈Mc+1[d(rm,ρ)>δ]\mu_c=\frac{1}{|\mathcal{M}_c^+|}\sum_{m\in\mathcal{M}_c^+}\mathbb{1}[d(r_m,\rho)>\delta]
δ\delta

The passage around this formula

…measures, among the trait-positive models in class c (the set Mc+\mathcal{M}_c^+ ), what fraction produce a response diverging from the seeded canonical form ρ\rho by more than a fixed threshold δ\delta under a declared distance function d : a high μc\mu_c says the trait is drifting as it moves, not being copied verbatim. The selection coefficient s=ln⁡\ln(ppost/(1−ppost)ppre/(1−ppre))\left(\frac{p_{\mathrm{post}}/(1-p_{\mathrm{post}})}{p_{\mathrm{pre}}/(1-p_{\mathrm{pre}})}\right) measures how a curation step — a filter, a…
