In the Clark-Hatfield street study, 75% of men agreed to have sex with an attractive stranger who approached them on campus, while exactly 0% of women agreed to the same offer.

Moving to personality, Stewart-Williams focuses on the two most consistent sex differences in the Big Five: neuroticism (women higher, ~0.2–0.5 SD) and agreeableness (women higher, ~0.2–0.5 SD). Neuroticism is explained as the flip side of male risk-taking — anxiety is self-protective, and women evolved more of it because the cost-benefit calculus of risk is different when your ceiling offspring number is lower. Agreeableness maps onto reduced within-sex competition and stronger selection for cooperative, compassionate social bonding. Smaller differences in openness, conscientiousness, and extraversion are noted. The episode's most empirically striking finding in this section is the people-versus-things career interest gap [1] — Steve Stewart-Williams "People vs things difference found in 80/80 nations: The sex difference in people-versus-things career interests was found in 53 out of 53 n…" 2:06:40 : an effect size of around one standard deviation or more, first documented in 1911, and found in 53/53 nations in one study and 80/80 in another with half a million participants. Despite decades of deliberate social pressure to close it, the gap has not budged. Its persistence through the gender equality paradox — growing larger in more egalitarian societies — is one of the strongest arguments for an innate contribution.
In the Clark-Hatfield study, a good-looking stranger approached random campus students offering a date, a visit to their room, or immediate sex. For the sex offer: 75% of men said yes, 0% of women did. Men who declined apologised and asked for a rain check. Women who were approached simply reacted with disgust.
The sex difference in people-versus-things career interests was found in 53 out of 53 nations in one study and 80 out of 80 nations in another, making it one of the most cross-culturally universal findings in social science.
The sex difference in people-versus-things career interests was first documented in 1911 and has remained consistent ever since, predating most modern gender role pressures.
Animals first sensed light 540 million years ago, triggering an evolutionary acceleration known as the Cambrian explosion within 10 million years.
It is estimated that half of all cortical activity in the human brain is involved in visual function, underscoring vision's central role in intelligence.
Cognitive neuroscience literature shows that by age 6, humans can recognize tens of thousands of different object categories — far more data than early AI systems were trained on.
Only about 3% of FDA-approved drugs have genuinely unclear mechanisms of action, making an unknown mechanism a meaningful early red flag for any compound.
Even compounds that clear preclinical testing often fail in humans: 30 to 50% of drugs entering phase 1 trials do not advance to phase 2, frequently because human behavior differs from animal models.
More than 80% of published BPC-157 research comes from a single academic group whose researchers have IP and commercial interests connected to the molecule, limiting independent replication.
Roughly 100 peptide drugs are already FDA-approved, about 150 more are in clinical trials, and 600–700 are in preclinical development, underscoring the legitimacy of peptide science broadly.
The scientist who discovered BPC-157 refused to disclose the screening method used to identify the compound and has never fully published the parent protein sequence — what Peter Attia calls 'scientific trust me, bro.'
The brain's visual, auditory, and motor cortices light up nearly identically whether an experience is real or imagined, making visualization a form of actual neural training.
