Higher IQ correlates with patience and risk aversion.
"Intelligent people tend to be patient because they have long time horizons."
This is likely a contributing factor to lower fertility rates among the intelligent.

Intelligent people (≥130 IQ) have a lower risk of mental illness than average people (85-115 IQ), while unintelligent people (≤70 IQ) have a significantly higher risk.
"Studies reporting that highly intelligent individuals have more mental health disorders often have sampling bias, no or inadequate control groups, or insufficient sample size. We addressed these caveats by examining the difference in the prevalence of mental health disorders between individuals with high and average general intelligence (g-factor) in the UK Biobank."

"Brains don't fully mature until age 25!" is pseudoscience weaponized by feminists to justify bad behavior. It has been refuted by mainstream academics, libtard mainstream media, and it even has a Wikipedia refutation.
The concept of a "fully mature" brain is also pseudoscience. This is a complex topic so I will attempt to simplify...
Brain "maturation" = neural pathways becoming stabilized, large reduction in passive neuroplasticity (automatic rewiring), pruning of weak/unused pathways, and so on.
Different brain regions "mature" at different ages, with some individual variability (and presumably some variation between races and sexes).
Brainstem/hindbrain = infancy
Sensory & motor cortex = childhood
Limbic system = adolescence
Prefrontal cortex = early to mid 20s
Social cognition network = early 30s
Hippocampus = never.
Conversely, brain regions begin to decline at different ages/rates. The prefrontal cortex, which feminists constantly ramble on about, is the first to decline — a mere half decade after it "matures"! This is why fluid IQ (raw problem-solving ability) peaks during the early 20s.
Brain maturation does not necessarily equate to "more adult" behavior, it means that your brain no longer adapts automatically. If you have a dysfunctional brain when it reaches "maturity," it can be difficult to repair; I'm sure you've met many old farts who behave like little kids.
"Mature brain" pathways become more efficient, whether they are beneficial to the individual or not, and harder (but not impossible) to change. You can maintain active neuroplasticity via exercise, metabolic health, constant learning, etc., and in this way "repair" a dysfunctional brain, but it requires conscious effort.
Brains continually change throughout our lifetimes, geared toward different tasks at different stages. So, at what point do we define "full maturity"? The brain hardware + fluid IQ peak of early 20s-30s? Crystalized IQ peak of 60s-70s? "Emotional intelligence" peak of mid 40s?

Kate Mills, a developmental neuroscientist at the University of Oregon, was equally puzzled. “This is funny to me—I don’t know why 25,” Mills said. “We’re still not there with research to really say the brain is mature at 25, because we still don’t have a good indication of what maturity even looks like.”
According to a 2016 Neuron paper by Harvard psychologist Leah Somerville, the structure of these and other brain areas changes at different rates throughout our life span, growing and shrinking; in fact, structural changes in the brain continue far past people’s 20s. “One especially large study showed that for several brain regions, structural growth curves had not plateaued even by the age of 30, the oldest age in their sample,” she wrote. “Other work focused on structural brain measures through adulthood show progressive volumetric changes from ages 15–90 that never ‘level off’ and instead changed constantly throughout the adult phase of life.”

Brain matures at 25 myth

Sewall Wright, the inventor of Fst (fixation index, a method of measuring genetic differentiation between populations) said "there is no question" that human races should "be considered to be of different subspecies."
Many animal species have lower Fst (less genetic differentiation between subpopulations) than humans.
Humans (5 or 6 subspecies) = ~0.15
African buffalo (5 subspecies) = 0.059
"It does not require a trained anthropologist to classify and array of Englishmen, West Africans, and Chinese with 100% accuracy by features, skin color, and type of hair, in spite of such much variability within each of these groups that every individual can easily be distinguished from every other."

156,200 permanent residence permits (-27.3%)
60,000 deportations (-68.4%)
~840,000 illegals in total (source; accuracy unknown).
Ethnic Russians are ~70% of the total population (2021 data, probably lower now).

SSRIs:
They more than double a patient's risk of suicide.

They cause sexual dysfunction in 83% of patients, some of whom experience these effects even after quitting SSRIs.
- https://doi.org/10.1159/000091777
They turn patients into emotionless, apathetic zombies; the effect is dose-dependent.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC2989833/
They increase risk-taking behavior, disinhibition, impulsivity.

Correction: The prefrontal cortex does NOT "mature" early-to-mid 20s: It depends on what you measure. Intracortical myelination — a better biomarker than gray matter thickness, studied in the old "brain matures at 25" study — peaks during the mid-to-late 30s.
The steady myelination decline following the mid-to-late 30s peak results in reduced efficiency: worse problem solving, decision making, memory, processing speed, etc. Brain hardware doesn't revert back to "adolescent" building/learning phase, it just deteriorates slowly.
The "brain matures at 25" claim doesn't even come from the old study, since their sample was age 4 to 21; it was the authors' guesstimate from interviews conducted after the paper was published.
(Debunking myself because I found a paper I saved 3 years ago)

Age of first-time months in America, 1980 versus 2016:
In 1980, the modal age of first-time mothers was 19, and the percentage of 16-year-old first-time mothers was almost double that of 30-year-old first-time mothers.
In 2016, the percentage of 18- and 30-year-old first-time mothers is practically equal, and 20-years-old has taken the modal spot from 28-years-old by a minute fraction of a percentage.
