The sex difference in verbal aggression has an effect size of about 0.5, but for homicide the gap is enormous — men perpetrate 90%+ of killings in every nation where data exists.

Both sexes are prone to jealousy, but the triggers differ systematically. For men, sexual infidelity is typically more distressing than emotional infidelity because it introduces paternity uncertainty — the only species-wide reproductive threat unique to males. For women, emotional infidelity tends to be more distressing because it signals probable desertion: a partner who falls in love with someone else is likely to leave, which was historically catastrophic for a woman with dependent children. This asymmetry generates different mate-guarding behaviour: men are more focused on monitoring sexual access, women on monitoring emotional commitment. A 23andMe anecdote about a paternal affair discovered three decades later prompts a discussion of how jealousy evolved as a gut reaction that fires regardless of whether the evolutionary circumstances still apply — another illustration of proximate versus ultimate causation.
The verbal aggression gap between men and women is modest. The physical aggression gap is bigger. For homicide, it's enormous — men perpetrate over 90% of killings in every nation where data exists. The same pattern appears in chimpanzees, where males commit 92% of chimpicides. This is reproductive variance made lethal.
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.
