Evaluation as inference denotes a family of methodologies in which evaluation is treated as a statistical, causal, logical, or decision-theoretic inference problem rather than as the mere reporting of a score. In this view, evaluators specify an evaluation condition or data-generating process, define target quantities such as treatment effects, size, coverage, bias, win rates, success probabilities, or protection rates, and then infer those quantities from measurements, simulations, verifier outputs, or adversarial probes under explicit assumptions about calibration, equivalency, sampling, and causality [2404.00021][1912.08772][2509.02892]. Across these formulations, evaluation becomes an experiment plus inference: outcomes are measured, uncertainty is quantified, and decisions are tied to confidence intervals, credible intervals, posterior distributions, or sequential tests rather than to ad hoc summaries alone [2404.00021][2512.03109]. ## 1. Ontology and general formulation A general formulation appears in “Evaluatology: The Science and Engineering of Evaluation” [2404.00021]. There, evaluation is organized around *subjects*, *evaluation conditions* (ECs), *evaluation models* (EMs), *measurement and testing*, and *evaluation results*. The EC is formalized as $C = E' \times E \times A' \times A \times S$, where $E'$ is the problem/task space, $E$ the space of problem/task instances, $A'$ the algorithm-like mechanism space, $A$ the implementation space, and $S$ the support system space. The EM is then $M = C \times U$, with $U$ the subject space, and observed outcomes are written as $y = (\rho(m), \tau(m))$, where $\rho(\cdot)$ denotes measurement and $\tau(\cdot)$ testing. Composite evaluation results are obtained through a value function $r = v(y)$ [2404.00021]. This formalization makes explicit that evaluation depends on what is held fixed, what varies, and what inferential quantity is extracted from observations. The same paper introduces five axioms: the Axiom of the Essence of Composite Evaluation Metrics, the Axiom of True Evaluation Outcomes, the Axiom of Evaluation Traceability, the Axiom of Comparable Evaluation Outcomes, and the Axiom of Consistent Evaluation Outcomes [2404.00021]. It also distinguishes *Equivalent Evaluation Conditions* and *Least Equivalent Evaluation Conditions*, thereby making comparability itself an inferential assumption rather than a default property of benchmark scores. A related framing appears in Ferman’s “Assessing Inference Methods” [1912.08772]. There, evaluation is explicitly described as the estimation of performance functionals—size, coverage, bias, variance, and power—under a specified data-generating process. The paper emphasizes that these quantities are not known; they are estimated with uncertainty from finite Monte Carlo replicates. The Monte Carlo estimate of expected loss is \[ \widehat{\mathbb{E}[L]} = \frac{1}{R}\sum_{r=1}^R L\big(M(Y^{(r)}),\theta\big), \] with Monte Carlo standard error \[ \operatorname{MCSE}\big(\widehat{\mathbb{E}[L]}\big) = \sqrt{\frac{\hat{\sigma}^2}{R}}. \] This shifts attention from single benchmark numbers to the inferential status of the benchmark itself [1912.08772]. Taken together, these formulations suggest that “evaluation as inference” is not a single method but a methodological stance: evaluation requires a target, a model of uncertainty, a controlled comparison structure, and an explicit account of what conclusions are warranted under the chosen design. ## 2. Estimands, uncertainty, and inferential machinery Several papers instantiate this stance by defining evaluation targets as estimands with explicit inferential operators. In “Statistical Inference for Score Decompositions,” expected forecast scores are decomposed into miscalibration, discrimination, and uncertainty, \[ S_i = MCB_i - DSC_i + UNC, \] and inference is performed on these components rather than only on aggregate predictive scores [2603.04275]. This decomposition connects score-based evaluation to classical calibration tests such as Mincer–Zarnowitz regression and financial backtests, and enables tests for equal calibration or equal discrimination under both smooth and non-smooth scoring functions [2603.04275]. In “Efficient Inference for Noisy LLM-as-a-Judge Evaluation,” the estimand is typically a mean parameter such as average benchmark score or pairwise win rate, but the observed judge output $Z$ is treated as a noisy surrogate for latent ground truth $Y$ [2601.05420]. The paper studies two corrective families—measurement-error correction and prediction-powered inference—and derives efficient influence function based estimators. Under the surrogate-outcome formulation, with $m(x,z)=\mathbb{E}[Y\mid X=x,Z=z]$, the efficient estimator is \[ \hat{\psi}_{\mathrm{EIF}} = \frac{1}{|U|}\sum_{i\in U}\hat{m}(X_i,Z_i) + \frac{1}{|L|}\sum_{j\in L}\bigl[Y_j-\hat{m}(X_j,Z_j)\bigr], \] which makes inference depend on both abundant noisy evaluations and a small labeled calibration set [2601.05420]. The paper’s central claim is that evaluation with LLM judges should be treated as inference with noisy surrogates, not as direct observation. A third formulation appears in “Prediction-Powered Inference Across Many Tasks for AI Evaluation & Social Science Research,” where the per-task estimand is the finite-population mean \[ \theta_k=\bar Y_N^{(k)}=\frac{1}{N_k}\sum_{i=1}^{N_k}Y_i^{(k)}, \] and cross-task recalibration exploits shared structure in the proxy–ground-truth relationship to improve per-task confidence intervals while preserving task-specific inference [2605.29249]. The paper proves that efficiency gains beyond power-tuned PPI are only possible when the proxy–ground-truth relationship contains nonlinear structure; affine cross-task recalibrations are asymptotically equivalent to using the original proxy [2605.29249]. These works differ in domain and mathematical apparatus, but all treat evaluation metrics as estimators or decompositions of latent quantities whose uncertainty must be modeled explicitly. ## 3. Causal evaluation and benchmarking A major strand of evaluation-as-inference arises in causal evaluation, where the objective is to infer treatment effects or estimator performance under counterfactual uncertainty. In “Bayesian causal inference in automotive software engineering and online evaluation,” randomized field experiments remain the gold standard, but the paper argues that in the automotive domain randomization is “not always desired, possible, or even ethical” [2207.00222]. It introduces BOAT, “Bayesian causal modelling for ObvservAtional Testing,” and presents three Bayesian causal inference models for three common challenges: Bayesian propensity score matching, Bayesian regression discontinuity design, and Bayesian difference-in-differences [2207.00222]. The abstract’s core claim is that online software evaluation can be enabled “without the need of a fully randomised experiment” when causal assumptions are modeled explicitly [2207.00222]. “Improving Generative Methods for Causal Evaluation via Simulation-Based Inference” moves the inferential burden to the benchmark itself [2509.02892]. SBICE treats the evaluation of causal estimators as a posterior predictive problem over uncertain data-generating-process parameters. Rather than fixing the average treatment effect or confounding strength to point values, it places priors over generative parameters, infers their posterior with SMC-ABC, and evaluates estimators on posterior predictive synthetic datasets filtered to be close to the source distribution [2509.02892]. In this formulation, estimator performance is integrated over the posterior, \[ \mu_E = \mathbb{E}_{\theta \mid D_s}[m(E;D_{\text{sim}}(\theta))], \] so that benchmarking itself becomes posterior inference rather than fixed-scenario comparison [2509.02892]. Benchmark construction papers make the same move from different directions. The IBM “Benchmarking Framework for Performance-Evaluation of Causal Inference Analysis” simulates full counterfactual outcomes on real-world covariates and evaluates submissions using ENoRMSE, RMSE, Bias, Coverage, CIC, and ENCIS, with separate scaling and censoring tracks [1802.05046]. “An evaluation framework for comparing causal inference models” complements mean ATE error and PEHE with performance profiles of Dolan and Moré, the Friedman test, and the Bergmann–Hommel procedure, explicitly to reduce the influence of a small number of simulations dominating the benchmarking process [2209.00115]. This literature treats evaluation as inference at two levels simultaneously: first, in estimating causal effects from observational data; second, in inferring comparative properties of causal estimators from synthetic or semi-synthetic benchmarks. ## 4. Language, inference, and adversarial evaluation In natural-language evaluation, the phrase acquires a more literal meaning: quality is evaluated through inferential relations rather than surface similarity. “MENLI: Robust Evaluation Metrics from Natural Language Inference” argues that many BERT-based metrics are models of semantic similarity and therefore do not directly capture information correctness [2208.07316]. MENLI instead uses NLI posteriors over entailment, contradiction, and neutral labels, with task-dependent directional choices and pooling functions, thereby treating evaluation as inference over whether candidate claims follow from a source or reference [2208.07316]. The paper’s broader claim is that correctness is an entailment problem, not a similarity problem. “Stress Test Evaluation for Natural Language Inference” makes a related argument from the model-evaluation side [1806.00692]. It proposes automatically constructed stress tests that isolate inferential phenomena—word overlap, negation, length mismatch, antonymy, numerical reasoning, and spelling errors—and examines whether NLI systems can make “real inferential decisions” under label-preserving perturbations [1806.00692]. Here evaluation becomes a probe of logical invariance and targeted reasoning competence, not merely aggregate accuracy on SNLI or MultiNLI [1806.00692]. “Ordinal Common-sense Inference” extends the idea further by replacing binary entailment with ordinal plausibility judgments [1611.00601]. Given a context $x$ and a hypothesis $h$, the task is to predict one of five likelihood levels—very likely, likely, plausible, technically possible, or impossible—thereby evaluating a model’s estimate of graded plausibility rather than its assignment to a categorical truth state [1611.00601]. This explicitly reframes recognition of textual entailment as inference over ordinal human responses. The same inferential turn appears in privacy evaluation. “Subject-level Inference for Realistic Text Anonymization Evaluation” argues that span masking does not measure what an adversary can infer after anonymization [2604.21211]. SPIA therefore shifts the unit of evaluation from text spans to identifiable individuals and defines subject-level protection metrics: \[ \text{CPR} = 1 - \frac{\sum_{i=1}^{N} A_i}{\sum_{i=1}^{N} O_i}, \qquad \text{IPR} = \frac{1}{N}\sum_{i=1}^{N}\left(1 - \frac{A_i}{O_i}\right), \] where $A_i$ is the adversarially inferred score for subject $i$ and $O_i$ the number of ground-truth PIIs for that subject [2604.21211]. The benchmark’s central finding is that even when over 90% of PII spans are masked, subject-level inference protection can remain low because contextual inference is still possible [2604.21211]. ## 5. Interactive, human-centered, and sequential inference Evaluation-as-inference also appears in settings where the evaluator is a human reasoner or an online monitor rather than an offline benchmark script. “Inferential Tasks as an Evaluation Technique for Visualization” introduces *inferential tasks* as a structured task family in which participants generate or inspect a visualization, infer a candidate observation, explore the dataset to find a different subset exhibiting the same characteristic, and validate the finding [2205.05712]. The method is explicitly positioned between low-level tasks and open-ended insight studies, with observable outcomes such as accuracy, speed, search breadth, and validated findings [2205.05712]. The paper’s thesis is that visualization should be assessed by observing and measuring the user’s inferential reasoning with data. “InFerActive: Towards Scalable Human Evaluation of Large Language Models through Interactive Inference” treats human evaluation not as inspection of isolated outputs but as interactive exploration of an LLM’s deterministic probability space induced by autoregressive generation [2512.10234]. The system represents the output space as a branching probability tree, where a response corresponds to a root-to-leaf path with probability \[ P(\text{path})=\prod_{i=1}^{L} p(t_i \mid t_{
