This preprint proposes CBAS, a scenario scale for comparing cognitive bias in people and LLMs, and combines representational similarity analysis (RSA) with social network analysis (SNA). It describes 58 biases grouped into Calculation, Belief, Information, Social, and Memory and operationalized through 72 items. More than 230 initial biases were reportedly reviewed and ten experts helped select them, but no item, response option, key, scoring rule, dimension mapping, or language version is published. A sample of 330 people aged 18-71 is used for psychometrics and a second sample of 110 younger and older adults is compared with ERNIE 3.5 8K, DeepSeek V3, and DeepSeek R1. Model parameters are temperature .9, top-p 1.0, and 2,000 maximum tokens. The paper reports overall alpha .714 and CFA fit of chi-square/df=1.83, RMSEA=.057, CFI=.908, and TLI=.903. Relations with CRT, DMC, and DOI are reduced to p<.05, while an RNN clustering procedure is said to agree 89% with the dimensions. In the comparison, human variability is reported as SD=16.68 versus 4.95-9.78 for models, without defining the measure or repetitions. Average connectivity is .107 for younger adults, .150 for older adults, .055 for ERNIE, .036 for DeepSeek V3, and .097 for R1. The paper interprets younger adults as Calculation-centered, older adults as Social-centered, and models as having fixed cores with isolated Information. Two prompts, a cognitive-scientist role and that role plus explicit mitigation, aim to change behavior. DeepSeek V3 reportedly rises from 48.65% to 78.24% accuracy and R1 from 70.43% to 84.86%; no ERNIE result is given. These numbers do not yet validate CBAS or a cognitive architecture. There is a material version conflict: Methods says 72 items, but visible matrix axes reach Q92/Q93 and include groups such as Q90_Q91_Q92 plus average/unnamed fields. The figures are not demonstrably based on the described instrument. Overall alpha also does not validate five subscales: no dimension alphas, omega, or test-retest estimate is provided; with 72 items, alpha .714 implies an average inter-item correlation of approximately .0335. EFA, CFA, IRT, MDS, genetic factor analysis, and RNN methods are listed without loadings, eigenvalues, parameters, estimator, ordinal treatment, residuals, complete results, or sample splitting. It is unknown whether EFA and CFA reuse the same 330 people. All p<.05 cannot establish criterion validity without effect sizes, directions, or multiplicity control, and the RNN's 89% lacks a target, baseline, and held-out validation. Age comparisons provide no cutoffs, group Ns, recruitment, demographics, or adjustment; they are cross-sectional and do not show within-person adaptation. The central RSA problem is identification. Methods says an item-by-item matrix is built for each participant and model through Pearson correlations among responses. One scalar response per item is insufficient to correlate item pairs; repeated observations or feature vectors must be defined. The paper does not say whether cells use participants, runs, tokens, embeddings, or another dimension. Model run counts and seeds are also absent despite temperature .9. Even if computed correctly, behavioral-output correlations describe response similarity, not hidden representations, activations, or architecture. SNA has the same issue: correlations among five dimensions for one model require a repeated sampling unit that is not defined. Only connectivity and qualitative labels are tabulated, not the announced centrality, density, and integration metrics. The RSA appendix omits ERNIE and provides no post-intervention matrix or network. Table 2 calls Information isolated in ERNIE, but its own graph draws several nonzero Information links. Intervention accuracy has no normative answer, scorer, denominator, parsing rule, or separate role-only versus role-plus-mitigation result. Calling the gain significant is unsupported by t, df, p, effect size, or interval; Methods also specifies an independent t test for a pre/post design on the same models and items, which is paired. Claimed post-intervention structural reorganization has no numerical or visual evidence. For reproducibility and ethics, CBAS, data, code, full prompts, outputs, and analyses are absent. The 440 participants, health-history screening, and responses are reported without an ethics board, consent, privacy procedure, compensation, or recruitment description. Linguistic equivalence between the human population and Chinese models is undocumented. Several references are mis-cited or unverifiable as written, including citations used to motivate LLM RSA. The useful contribution is the proposal to evaluate bias through scenarios rather than abstract accuracy alone; all numbers should be read as exploratory author-reported results, not validation of a replicable scale or evidence of internal cognitive mechanisms.
Research question
Can a contextual scale of 58 biases and 72 items compare the response structure of young, older, and three Chinese LLMs, and can role and mitigation prompts bring the patterns of the models closer to those of humans?
