Sexual selection does not lead nowadays to better genes. Good looks are positively correlated with intelligence and health, but only weakly so. There was a study "Human Capital Mediates Natural Selection in Contemporary Humans."

I'll copy-paste someone's summary: Traits are passed on to children, so the next generation will have more of the traits to the right of the dotted line, and fewer of those to the left. At the top, the traits most rapidly spreading in the next generation are ADHD, smoking, extraversion, high BMI, and large waist circumference. These last two are measures of fatness. Heart disease, depression, Alzheimer's, and schizophrenia are also on the right. To the left are the traits that are being bred out, and at the bottom, being bred out most rapidly, are three measures of intelligence.

So if intelligence is being bred out most radically, what does it tell about miladies' preferences? :D

I agree, it probably does not.

Good looks are positively correlated with intelligence and health, but only weakly so.

So if intelligence is being bred out most radically,

But how did you jump from weakly positively correlated, or even uncorrelated, to saying intelligence is radically selected against. You'd need a strong negative correlation to make this case, and according to you there isn't one.

Also, I'm not sure the health problems you mention are a result of sexual selection rather than a result of Americans having poor diets and exposure to environmental toxins. You say we are selecting for attractiveness and then say we are selecting for obesity, which would seem to contradict your idea about selecting for attractiveness

Read what polygenic risk scores mean https://www.genome.gov/Health/Genomics-and-Medicine/Polygenic-risk-scores

I haven't read the whole document I referred to above yet, but what it treats was genetic propensities to certain traits, and which of said traits are being selected for or against. Whether environment will compensate for something is wholly another matter.

If individuals with ADHD have constantly higher reproductive success, as the source indicates, this simply means more individuals will likely develop said disorder. I don't remember whether autism was listed in the graph, but anyone knows anyway that autists have very poor reproductive chances these days. Just bringing a comparison between two mental illnesses.

Also, I wouldn't like to jump into Caamib's territory, but last decades really show intelligence is being selected against. There's a collection of materials here: https://incels.is/threads/irrefutable-proof-of-the-hypergamy-and-why-the-current-mode-of-sexual-selection-is-dysgenic.396281/
