The pith

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The reading

This paper analyzes 129,297 customer reviews from six e-commerce datasets to test whether culture and gender shape the emotions expressed in text. It finds that Western reviewers score higher on sentiment, valence, arousal, and dominance than Eastern reviewers, and that the two groups differ on advanced emotion categories such as admiration, love, disappointment, and annoyance. Gender differences appear on valence, arousal, and dominance, with female reviewers scoring higher, but not on overall sentiment or basic emotion categories. The paper's new claim is the interaction: the male-female emotional gap is larger in Western cultures than in Eastern ones across sentiment, valence, dominance, and advanced emotions. If correct, consumer emotion analysis and marketing personalization should treat gender effects as culture-dependent.

What carries the argument

The central machinery is a text-emotion measurement pipeline plus a moderation test. Each review is scored by five machine-learning models producing a sentiment score, sentiment category, valence-arousal-dominance (VAD) scores, basic emotion categories, and 27 advanced emotion categories; group differences are then tested with multivariate analysis of variance, and the gender-by-culture interaction is estimated with moderation regression. The load-bearing object for the new claim is the moderation analysis, which tests whether the gender effect on each emotional outcome changes between Eastern and Western reviewers and produces the crossover plots showing the larger Western female-male gap.

What would settle it

Translate matched Eastern and Western reviews into a single common language, re-run the same emotion models, and check whether the larger Western female-male gap persists; if the gap follows the original language rather than the cultural group, the moderation result is a measurement artifact.

Core claim

The paper claims that gender-based emotional disparities in online customer reviews are more pronounced in Western cultures than in Eastern ones. Across four emotional outcomes—sentiment score, valence, dominance, and advanced emotion categories—the moderation analysis shows the female-male gap widening among Western reviewers. In the Eastern group, male sentiment scores are higher than female scores; in the Western group, female sentiment surpasses male. Similar patterns appear for valence and dominance, where females move from near parity in the East to higher scores in the West. The paper interprets this as evidence that cultural norms around emotional expression and gender roles jointly shape consumer emotion, an interaction that coarse sentiment-based studies have missed.

Load-bearing premise

That the five English-trained emotion-scoring models measure the same emotional construct in Eastern and Western reviews; otherwise the cultural and gender contrasts are artifacts of language or training bias.

Editorial extensions

If this is right

  • Global sentiment and emotion models should be calibrated by culture, because a single gender adjustment will misrepresent at least one market.
  • Marketing campaigns can use different emotional tones for male and female audiences in Western markets, while Eastern markets need smaller or reversed gender adjustments.
  • E-commerce feedback dashboards should report valence, arousal, and dominance alongside sentiment, since gender differences are invisible in coarse sentiment categories.
  • Future studies on consumer emotion should include the interaction of gender and culture rather than testing either factor alone.
  • Advanced emotion categories, not just basic ones, carry the cultural signal in customer reviews.

Reading between the lines

Editorial extensions of the paper, not claims the author makes directly.

  • An implication the paper leaves implicit is that emotion datasets pooled across cultures will overstate or understate gender differences depending on the cultural mix, even when each group is balanced.
  • The crossover pattern, with males higher in the East and females higher in the West, is consistent with cultural display rules shaping emotional expression more than emotional experience; separating the two would require physiological or behavioural measures.
  • A direct test of the measurement-invariance worry would be to translate matched reviews into a common language and re-run the same emotion models; if the Western gender gap follows language rather than culture, the moderation result is an artifact.
  • Rerunning the analysis separately by product category would show whether the interaction is driven by hedonic purchases, where emotional expression is more culturally salient.

Referee Report

5 major / 6 minor

Summary. The paper examines gender and cultural differences in customer emotions expressed in online reviews. It pools six e-commerce review datasets (FashionNova, Amazon, Celsius, ASOS, Qatar Airways, La Veranda), applies off-the-shelf NLP models to produce sentiment, valence, arousal, dominance, and basic/advanced emotion scores, and tests three hypotheses: culture affects emotional experiences (H1), gender affects emotional experiences (H2), and culture moderates gender effects (H3). The authors report significant cultural differences on most continuous measures, significant gender differences on valence, arousal, and dominance but not sentiment, and significant Gender×Culture interactions for sentiment, valence, dominance, and advanced emotions. They conclude that gender-based emotional disparities are more pronounced in Western than Eastern cultures.

Significance. If the results were valid, the paper would offer a useful intersectional contribution to consumer-emotion research and practical guidance for personalized marketing. The manuscript uses a large combined dataset (129,297 reviews) and multiple emotion measures beyond simple sentiment, which are strengths. However, the validity of the central claims is undermined by the lack of measurement-invariance testing, the absence of coding rules for gender and culture, and a confounding of the Gender×Culture interaction with dataset and product-domain composition. The abstract and summary tables also misrepresent nonsignificant results as significant support.

major comments (5)
  1. [Abstract, Table 4, Table 6] The abstract's claim that there are significant variations between male and female consumers 'across all sentiment, valence, arousal, and dominance scores' is contradicted by Table 4, where Sentiment Score (p = .387) and Sentiment Category (p = .156) are nonsignificant. In addition, §5.1 declares Hypothesis 1 fully confirmed even though Table 3 shows Basic Emotion Category is nonsignificant (p = .825) and Table 6 marks this outcome as 'Yes' for H1. The abstract and summary tables should be corrected to report partial support rather than full confirmation.
  2. [§3.2, Table 1, §4.3.2] The Gender×Culture moderation analysis is not identifiable because the pooled sample combines six heterogeneous sources (fashion, electronics, cryptocurrency, cosmetics, airline, and hospitality) and the PROCESS models in §4.3.2 include only Gender, Culture, and their interaction. If the proportion of male/female and Western/Eastern reviewers differs across these sources, the interaction coefficient is a composition artifact: the larger gap among 'Western' reviews could simply reflect fashion/beauty platforms and the smaller gap among 'Eastern' reviews could reflect crypto or airline platforms. The manuscript reports no gender-by-culture-by-dataset cross-tabulation and no dataset or product-category fixed effects, so the interaction cannot be attributed to gender and culture rather than to what products each group reviews.
  3. [§3.2, §3.4, Tables 3 and 5] The coding rules for gender and culture are never defined. The text says the datasets include demographic information, but it never states how reviewers were classified as male/female or Western/Eastern, and Culture appears as a numeric variable in the PROCESS analyses (with a high value of 3.0 in §4.3.2). In Tables 3 and 5, Culture has df = 2, which implies three categories, yet only Eastern and Western groups are discussed in the text. Without explicit coding rules and category definitions, the central comparisons are not reproducible.
  4. [§3.3, Table 2, §5.1, §5.4] The emotion scores are generated by English-oriented models (VADER, word2affect_english, bert-base-uncased-emotion, roberta-base-go_emotions), and the manuscript offers no measurement-invariance test across cultures or languages. The paper itself concedes in §5.1 that automated text models miss culturally specific phrasing and in §5.4 that model accuracy and interpretability remain unresolved. Because the cultural contrasts in §4.1 and §4.3.2 are based on these model outputs, the observed Western–Eastern differences could be artifacts of training-data and language bias rather than genuine differences in consumer emotion.
  5. [§4.3.2] The central claim that gender-based emotional disparities are more pronounced in Western cultures than in Eastern ones is not supported by the statistics reported. For each moderation model, the manuscript gives only overall R², R² change, and a conditional effect at one value of Culture (3.0); it does not report the interaction coefficient, its standard error, simple slopes at Eastern and Western levels, or a formal test comparing the magnitude of the gender gaps at the two cultural levels. The figures are illustrative but cannot establish moderation without the corresponding inferential contrasts.
minor comments (6)
  1. [§3.1] The conceptual model text swaps the hypotheses: it says 'H1, suggesting that gender influences emotional experiences; H2, indicating that culture has an impact,' but earlier sections define H1 as the culture hypothesis and H2 as the gender hypothesis.
  2. [Figure 1, Figure 2] Figure 1 contains 'Categorial Emotions' and Figure 2 contains 'emotion itensifies'; these should read 'Categorical Emotions' and 'emotion intensities.'
  3. [§4.3.1] The section heading is typeset as '4..3.1' (double period), which should be corrected.
  4. [Table 6] The header 'Basic Emotion CCategory' contains a typo, and the H1 row lists 'Yes' for Basic Emotion Category despite the nonsignificant result in Table 3.
  5. [§3.2] The paper states that 'the customer reviews apparently randomly sampled from various dataset categories' but does not explain how random sampling was performed or whether it was needed; this phrasing should be clarified.
  6. [§3.4] The claim that the dataset contains a relatively equal representation of male/female and Western/Eastern reviewers is not supported by any descriptive table or distributional statistics per dataset.

Circularity Check

0 steps flagged · score 0.0 of 10

No circularity: the emotion scores come from externally pretrained models and the group contrasts are new measurements, not algebraic rewrites of the inputs.

full rationale

The paper's derivation chain is empirical: collect six public review datasets with gender and culture metadata, apply five named pretrained NLP models (multilingual sentiment analysis, VADER, word2affect_english, bert-base-uncased-emotion, roberta-base-go_emotions) to obtain sentiment, valence, arousal, dominance, and emotion-category scores, and then run MANOVA and Hayes PROCESS moderation regressions comparing groups. The outcome variables are model outputs, not quantities fitted from the hypotheses they test. The H3 moderation result is the Gender x Culture interaction term in regressions of those model outputs on Gender, Culture, and their product; it is not defined in terms of the Western/Eastern or male/female differences it is claimed to explain. No parameter is fitted to one subset and then relabeled as a prediction of a closely related quantity. The self-citations (Truong 2022, 2023, 2024; Truong and Hoang 2022; Truong et al. 2020) appear in framing and literature-review sentences and are not load-bearing for the measurement, identification, or statistical conclusions. The real threats to the central claim are measurement invariance of English-trained emotion models across cultures and confounding of group labels with dataset/product domain; the manuscript itself concedes in Sections 5.1 and 5.4 that automated models miss culturally specific phrasing and that model accuracy and interpretability remain unresolved. These are validity and generalizability concerns, not circular reductions. Since no load-bearing step reduces by construction to its own inputs, the honest circularity finding is none, score 0.

Assumptions & free parameters 1 free parameters · 5 assumptions · 0 invented entities

The central claims depend on treating off-the-shelf emotion scores as true cross-cultural measures and on trusting self-reported or platform demographic labels. No measurement invariance testing, no label validation, and no platform controls are provided, so the statistical contrasts may reflect classifier bias or data artifacts rather than consumer emotion.

free parameters (1)
  • Culture numeric coding for PROCESS moderation = not reported; conditional effects evaluated at Culture = 3.0
    The moderation analysis in Section 4.3.2 treats Culture as a numeric moderator and evaluates gender effects at Culture = 3.0, but the paper never defines the coding of Eastern and Western into numeric levels. The sign and magnitude of conditional effects depend on this arbitrary coding.
assumptions (5)
  • domain assumption The pretrained sentiment, VAD, and emotion classifiers are measurement-invariant across genders and cultures.
    Section 3.3 applies English-centric models such as word2affect_english and roberta-base-go_emotions to reviews from Eastern and Western consumers without any invariance testing; if false, observed differences are classifier artifacts.
  • domain assumption Gender and cultural labels in the six source datasets are accurate.
    Section 3.2 states demographic information was used 'when available' and no verification procedure is described, so mislabeled or self-selected demographics could bias all group comparisons.
  • ad hoc to paper The Western/Eastern binary is a valid operationalization of cultural difference for these reviews.
    Hofstede's framework is invoked theoretically, but the paper never specifies how individual reviewers were assigned to Western or Eastern groups or how mixed or ambiguous cases were handled.
  • domain assumption MANOVA assumptions (normality, homogeneity of variance, independence) hold for the emotion scores.
    Section 3.4 only mentions skewness and kurtosis checks; no Levene's test, Box's M, or residual diagnostics are reported for the 129,297-review sample.
  • ad hoc to paper Reviews from six very different platforms can be pooled without platform or product-category confounding.
    Table 1 mixes fashion, electronics, cryptocurrency, cosmetics, airline, and restaurant reviews; no platform fixed effects or product-category controls are included, so culture is confounded with domain and language.

Understanding consumer emotional experiences on e-commerce platforms is essential for businesses striving to enhance customer engagement and personalisation. Recent research has demonstrated that these experiences are more intricate and diverse than previously examined, encompassing a wider range of discrete emotions and spanning multiple-dimensional scales. This study examines how gender and cultural differences shape these complex emotional responses, revealing significant variations between male and female consumers across all sentiment, valence, arousal, and dominance scores. Additionally, clear cultural distinctions emerge, with Western and Eastern consumers displaying markedly different emotional behaviours across the larger spectrum of emotions, including admiration, amusement, approval, caring, curiosity, desire, disappointment, optimism, and pride. Furthermore, the study uncovers a critical interaction between gender and culture in shaping consumer emotions. Notably, gender-based emotional disparities are more pronounced in Western cultures than in Eastern ones, an aspect that has been largely overlooked in previous research. From a theoretical perspective, this study advances the understanding of gender and cultural variations in online consumer behaviour by integrating insights from neuroscience theories and Hofstede cultural dimension model. Practically, it offers valuable guidance for businesses, equipping them with the tools to more accurately interpret customer feedback, refine sentiment and emotional analysis models, and develop personalised marketing strategies.
