More evidence for the attractiveness = health brigade.
“Instead, plasma cortisol level was negatively associated with attractiveness, indicating that stressed women look less attractive. Fat percentage was curvilinearly associated with facial attractiveness, indicating that being too thin or too fat reduces attractiveness. Our study suggests that in contrast to men, facial attractiveness in women does not indicate immune responsiveness against hepatitis B, but is associated with two other aspects of long-term health and fertility: circulating levels of the stress hormone cortisol and percentage body fat.”
That’s great except-
cortisol is part of the immune response process.
Biologists know this.
I’m at the stage where I can spot Royal Society errors in under five seconds.
Sort your variables out. Acute cortisol release is anti-inflammatory.
Fat also lets your body free up energy quickly to fight illness. You need “some” depending on your body (race, sex, energy needs, diet).
Some (correct) biologists want it relabeled as an organ.
“Researchers have found that fat plays an important role in protecting bones and organs, regulating hormones and the immune system and managing women’s reproductive systems.”
Women just need more fat (as a %) for pregnancy (it’s most of a year, come on).
Try studying men, I doubt it doesn’t manage theirs too.
Like the free metabolic energy is scared of testicles or something.
Study the signals, quit with the noise.
To prove my grief, read this sack of shit Intro.
Can you tell me what’s wrong with it?
“The growing field of evolutionary psychology reports a large body of evidence to suggest that standards of beauty are not arbitrary cultural conventions, pointing to, for example, cross cultural agreement in preferences for cues to health and fertility . Furthermore, a number of studies suggest that facial preferences emerge early in childhood, before any cultural standards of beauty are likely to be assimilated, suggesting we have a strong inborn universal standard of facial beauty . Evolutionary psychologists interpret preferences as strategies evolved owing to the selective benefits accrued to those who chose their mates based on these criteria (reviewed in Rhodes ). To argue that such preferences are adaptive, however, it is necessary to show that preferred traits serve as cues to fecundity, health or other traits that enhance fitness, and contribute to higher reproductive success.
Nature or nurture, fucking PICK ONE.
Studies linking facial attractiveness and health records in men, however, have found only weak or no association between facial attractiveness and health (reviewed in Rhodes ).
Recently, Rantala et al.  found that men’s ability to produce antibodies in response to the hepatitis B vaccine correlated positively with facial attractiveness, suggesting that men’s facial attractiveness indicates immunity in humans.
Vaccines. Evolution. Don’t use those two ideas in the same sentence.
I can and shall laugh at you derisively.
Thus, by choosing men with attractive faces as partners, women may get direct benefits by avoiding contagion and indirect benefit by increasing health and immunity of their offspring.
Because, in humans, both sexes are choosy,
one could predict that female facial attractiveness may also be associated with immune defence and sex hormone levels.
However, to our knowledge, studies testing association between female facial attractiveness, immune defence and stress hormone levels are lacking. Studies linking facial attractiveness with indices of health have led to mixed results:
Where’s “health” on a blood test?
while certain studies
have found some evidence
that facially attractive women are healthier [5–7], other studies have found no association [8–10].
Rantala et al.  found that the link between facial attractiveness and immune response in men was mediated by their facial adiposity, not their masculinity (facial masculinity was however associated with immune response, independently of facial adiposity). Thus, we could expect that adiposity in women is associated with the strength of immunity and attractiveness. The aim of this study was to test whether facial attractiveness in women is associated with the strength of their immune response, circulating levels of the stress hormone cortisol and adiposity.”
Proof you don’t publish Asians and assume they’re all smart.
This is in the Royal Society.
Guess the race of the diversity hire running this English historical society now?
Estrogen is inflammatory. Testosterone is anti.
(So guys bitching about women with endometriosis are idiots, they have more).
“Braude’s new idea is that testosterone signals infection-fighting white blood cells to go out of the blood stream and into the skin. He says it’s also possible that testosterone merely triggers the stress response, and other steroids from the adrenal gland then execute the redistribution.”
a woman with elevated testosterone won’t be more attractive
women are not men!
