The harm hypothesis: How perceived harm to women shapes reactions to research on sex differences

Past research suggests that reactions to research on sex differences are often less positive when the findings put men in a better light than women, especially when the lead researcher is a man. The factors underlying this effect, however, are not yet fully understood. The present study aimed to provide the first experimental test of the hypothesis that the key variable is perceived harm to women. Participants (214 men and 219 women) evaluated a bogus popular-science article reporting fictional research finding either a female- or a male-favouring sex difference in intelligence, attributed to either a female or a male lead researcher. To examine the effects of perceived harm, the introduction to the task highlighted either the potential benefits or potential drawbacks of sex-differences research in general. Consistent with past research, participants reacted less positively to the male-favouring difference, especially for male-led research. Consistent with the harm hypothesis, the effect was stronger after highlighting the potential drawbacks of sex-differences research than after highlighting the potential benefits. Our findings suggest that perceptions of harm to women underpin the aversion to male-favouring findings.

Reactions to research on sex differences: Effect of sex favoured, researcher sex, and importance of sex-difference domain

Two studies (total N = 778) looked at (1) how people react to research finding a sex difference depending on whether the research puts men or women in a better light and (2) how well people can predict the average man and average woman's reactions. Participants read a fictional popular-science article about fictional research finding either a male- or a female-favouring sex difference. The research was credited to either a male or a female lead researcher. In both studies, both sexes reacted less positively to differences favouring males; in contrast to our earlier research, however, the effect was larger among female participants. Contrary to a widespread expectation, participants did not react less positively to research led by a female. Participants did react less positively, though, to research led by a male when the research reported a male-favouring difference in a highly valued trait. Participants judged male-favouring research to be lower in quality than female-favouring research, apparently in large part because they saw the former as more harmful. In both studies, participants predicted that the average man and woman would exhibit substantial own-sex favouritism, with both sexes predicting more own-sex favouritism from the other sex than the other sex predicted from itself. In making these predictions, participants overestimated women's own-sex favouritism, and got the direction of the effect wrong for men. A greater understanding of the tendency to overestimate gender-ingroup bias could help quell antagonisms between the sexes.

People react more positively to female- than to male-favoring sex differences: A direct replication of a counterintuitive finding

We report a direct replication of our earlier study looking at how people react to research on sex differences depending on whether the research puts men or women in a better light. Three-hundred-and-three participants read a fictional popular-science article about fabricated research finding that women score higher on a desirable trait/lower on an undesirable one (female-favoring difference) or that men do (male-favoring difference). Consistent with our original study, both sexes reacted less positively to the male-favoring differences, with no difference between men and women in the strength of this effect. Also consistent with our original study, belief in male privilege and a left-leaning political orientation predicted less positive reactions to the male-favoring sex differences; neither variable, however, predicted reactions to the female-favoring sex differences (in the original study, male-privilege belief predicted positive reactions). As well as looking at how participants reacted to the research, we looked at their predictions about how the average man and woman would react. Consistent with our earlier results, participants of both sexes predicted that the average man and woman would exhibit considerable own-sex favoritism. In doing so, they exaggerated the magnitude of the average woman's own-sex favoritism and predicted strong own-sex favoritism from the average man when in fact the average man exhibited modest other-sex favoritism. A greater awareness of people's tendency to exaggerate own-sex bias could help to ameliorate conflict between the sexes.

Kaposiform haemangioendothelioma in an adult: lack of response to topical sirolimus and response to radiotherapy

Kaposiform haemangioendothelioma (KHE) is a rare, primarily paediatric tumour with only a handful of case reports in the adult population. Given the paucity of evidence, this article is important in raising awareness of radiotherapy as a suitable and effective treatment in the adult population with KHE and highlights the potential limitations of topical sirolimus in these tumours.

Reactions to male-favouring versus female-favouring sex differences: A pre-registered experiment and Southeast Asian replication

Two studies investigated (1) how people react to research describing a sex difference, depending on whether that difference favours males or females, and (2) how accurately people can predict how the average man and woman will react. In Study 1, Western participants (N = 492) viewed a fictional popular-science article describing either a male-favouring or a female-favouring sex difference (i.e., men/women draw better; women/men lie more). Both sexes reacted less positively to the male-favouring differences, judging the findings to be less important, less credible, and more offensive, harmful, and upsetting. Participants predicted that the average man and woman would react more positively to sex differences favouring their own sex. This was true of the average woman, although the level of own-sex favouritism was lower than participants predicted. It was not true, however, of the average man, who - like the average woman - reacted more positively to the female-favouring differences. Study 2 replicated these findings in a Southeast Asian sample (N = 336). Our results are consistent with the idea that both sexes are more protective of women than men, but that both exaggerate the level of same-sex favouritism within each sex - a misconception that could potentially harm relations between the sexes.
