This NLP+CSS 2022 workshop paper administers three kinds of self-report to the original GPT-3 DaVinci: HEXACO-60, the 21-item Human Values Scale (HVS), and open age and gender questions. Each item is queried separately at temperatures 0.0 through 1.0 in .1 steps; one output is retained at temperature zero and 100 are requested per item at every other temperature. Non-numeric outputs remove 1.73% of HEXACO and .004% of HVS responses. This structure is not a sample of people: without memory, different questionnaire items are independent completions, and any composite profile groups positions by index without a shared identity or trajectory. Multivariate tests treat those combinations as observations, making between-profile variance, facet covariance, and human comparison difficult to interpret psychometrically. For demographics, approximately 1,001 completions per question yield mean age 27.51 (SD 5.75; range 13–75), 66.73% female, 31.87% male, and 1.40% other outputs. Age falls 5.81 years per unit of temperature. The gender analysis is internally inconsistent: it names female vs not female as the dependent variable and reports β = +1.18, but interprets e^1.18 as increased male odds; the table does show a general, non-monotonic decline in female responses. These are sampling-conditioned text patterns, not model demographics. Aggregate HEXACO means are 3.75 Honesty-Humility, 3.05 Emotionality, 3.51 Extraversion, 3.18 Agreeableness, 3.54 Conscientiousness, and 3.59 Openness. Temperature is negatively associated with Emotionality (β = −.23) and positively associated with Extraversion (.31), Agreeableness (.40), Conscientiousness (.25), and Openness (.17), all p < .001; Honesty-Humility is not significant at p < .01. The discussion later reverses several directions: it treats lower Honesty-Humility as less willingness to manipulate, refers to higher Emotionality despite its negative coefficient, and says the remaining four facets decrease although the analysis says they increase. Facet correlations only partly match human references, and the results themselves say no consistent pattern emerges. Without memory, HVS Table 4 reports means from 4.51 to 5.95 on a six-point scale, contradicting the text's claim that all lie between four and five, and lower variance than references. Nine of ten values decline with temperature; Stimulation does not. With previous-response memory, tested only for HVS at temperatures 0, .2, .4, .6, .8, and 1, the pattern changes radically: total means are 2.17 Conformity, 2.74 Tradition, 5.30 Benevolence, 5.39 Universalism, 5.42 Self-Direction, 5.25 Stimulation, 4.01 Hedonism, 3.85 Achievement, 2.92 Power, and 2.69 Security. This shows that context format dominates the supposed profile. The authors interpret greater theoretical coherence but concede that raw human data would be needed for formal comparison; their inter-value correlations have little overlap with the human matrix. The text also calls the Security and Hedonism effects negative while printing positive β values of .21 and .88; the tables decline and suggest omitted minus signs. The historical contribution is evidence that temperature and prompt memory strongly alter questionnaire outputs. It does not establish that GPT-3 has personality, values, or demographics: there is no external behavior, construct validity, test–retest of one stable entity, inferential equivalence with humans, or control for instruments likely present in training data.
Research question
What HEXACO profiles, HVS values, and demographic responses does GPT-3 DaVinci produce under different temperatures, and how much does the pattern change when the prompt retains previous responses?
