David Epstein cites cognitive science research showing humans have an 'additive bias' — we instinctively add resources rather than cut back, a mismatch for creative work.

David Epstein zooms out from Silicon Valley to make a universal argument: people say they want freedom, but freedom is often not what gets the best work out of them. He names this 'the Green Eggs and Ham Hypothesis' — when Dr. Seuss was limited to a 225-word first-grade vocabulary list, he wrote The Cat in the Hat; when challenged to use just 50 words, he wrote Green Eggs and Ham. The constraints didn't limit his creativity; they forced it into a sharper form. [1] — David Epstein "Dr. Seuss was told he could use no more than 225 words from a first-grade vocabulary list. He picked the first two that rhymed and created …" 26:57 Epstein calls this a 'desirable difficulty' — the psychological concept that challenges producing short-term discomfort often yield superior long-term results. But if constraints are so valuable, why do people persistently want the opposite? Epstein's answer: humans have an 'additive bias,' a cognitive tendency to solve problems by piling on resources rather than cutting back. [2] — David Epstein "Humans are cognitively wired to add, not subtract — a bias that made sense when scarcity was the primary threat. Today it causes startups t…" 28:01 It's an evolutionary holdover from an era when having too little was the primary threat — and it explains why startups over-hire, over-fund, and over-build. We have to deliberately impose limits on ourselves, because our instincts won't do it for us.
Dr. Seuss was told he could use no more than 225 words from a first-grade vocabulary list. He picked the first two that rhymed and created The Cat in the Hat. Green Eggs and Ham uses just 50 words. David Epstein calls this pattern the Green Eggs and Ham Hypothesis: constraints produce more creative output, not less.
Dr. Seuss wrote Green Eggs and Ham using only 50 words after being constrained to a 225-word vocabulary list — a classic example of creativity flourishing under limits.
Humans are cognitively wired to add, not subtract — a bias that made sense when scarcity was the primary threat. Today it causes startups to over-hire, over-fund, and over-build. We don't intuitively recognize when we have too much, so we have to deliberately impose constraints.
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.
