“Smoking increases androgen levels in women.”

Smoking is generally associated with modestly higher levels of some androgens in women. A 2022 meta-analysis and several clinical studies support this pattern, although an earlier meta-analysis found no clear association for testosterone specifically. Because the evidence is predominantly observational and varies by hormone and menopausal status, it does not firmly establish that smoking directly causes an increase in every androgen across all women.

“Men experience greater overall life hardship than women.”

The evidence does not support ranking men as experiencing greater hardship overall. Men fare worse in mortality, suicide, and occupational danger, while women face substantial disadvantages in discrimination, poverty, financial security, development, and gender-based violence. Because no validated measure combines these burdens into an overall comparison, treating male-specific harms as decisive is unjustified.

“Excessive dietary salt intake lowers estrogen levels in women.”

The evidence does not support the claim that excessive dietary salt intake lowers estrogen levels in women. The only direct human study cited found that changing sodium intake did not alter estrone or estradiol in postmenopausal women. Studies in this evidence set mainly show the opposite relationship: estrogen influences salt sensitivity and fluid balance, while animal findings suggesting hormonal changes with high salt do not establish the same effect in women.

“When controlling for relevant variables such as occupation, experience, and hours worked, women do not earn less than men for the same work.”

Multiple large-scale studies and government or peer-reviewed analyses find that even after adjusting for job title, experience, and hours, women still earn slightly less—usually 1–5 %—than men doing comparable work. A trade publication’s report of nine states with no measured gap is an outlier and does not negate the broader, well-documented residual disparity. Therefore, the assertion that controls eliminate the pay gap everywhere is not supported.

“Fasting is not healthy for women who have high cortisol levels.”

While fasting does acutely raise cortisol and women show sex-specific changes in cortisol rhythm, the peer-reviewed evidence does not establish that fasting is clinically harmful for women with pre-existing high cortisol levels. The claim conflates a measurable hormonal response with demonstrated health harm—a logical leap unsupported by the highest-quality studies available. Sources making the stronger causal claim are predominantly wellness blogs and commercial health platforms, not clinical research on this specific population.

“Women are more emotionally driven than men in decision-making contexts.”

The scientific evidence does not support the broad claim that women are more emotionally driven than men in decision-making. Peer-reviewed meta-analyses and empirical studies show that sex differences in emotional influence on decisions are small, task-specific, and inconsistent in direction — with some research finding men more susceptible to emotional spillover in financial decisions. The claim relies on conflating emotional sensitivity or neural activation with emotion-dominated choices, a logical leap that neuroscience research explicitly cautions against.

“Statistical data shows that women have worse driving records than men.”

This claim is false. The most authoritative data — from the Insurance Institute for Highway Safety (IIHS) and peer-reviewed research — consistently shows that men have higher crash rates than women when properly adjusted for driving exposure. Men's fatal crash involvement per 100 million miles is 63% higher than women's. The argument that women have "worse records" relies on poorly defined per-capita metrics from low-authority law-firm blogs, which lack valid denominators and conflict with rigorous, exposure-controlled studies.
