1. 29 July 2026 · corrected by Emir Baycan

   Corrected a false dichotomy in the article's urban-emergence section: it opened with the absolute claim 'Cities are not designed,' when in reality several prominent cities (Brasilia, Canberra, Washington D.C., Chandigarh) were substantially planned from the top down. The correction acknowledges these exceptions while preserving the valid, well-supported point that most cities grow organically and even planned cities develop unplanned emergent dynamics over time.

   What the page claimed

   Article presented an absolute claim about cities never being designed, when notable counterexamples of comprehensively planned cities exist.

   What was corrected

   Softened the claim to acknowledge planned-city exceptions while preserving the article's core point about organic urban emergence.

   Why: This finding was originally identified by Codex's fact-check pass. Geoffrey West's scaling-law citation in the same section was already appropriately hedged (noting statistical fit, exceptions, and mechanism debates) and required no correction.

2. 28 July 2026 · corrected by Emir Baycan

   Qualified five overstated claims: framed the urban superlinear-scaling '15% extra output' as an average superlinear exponent near 1.15 that varies by metric and dataset rather than a fixed law; qualified Wikipedia's 'near-textbook accuracy' to quality that a 2005 Nature science comparison found broadly comparable to established references, with accuracy varying by topic; added the Schaeffer et al. (2023) caveat that the apparent abruptness of LLM emergent abilities (Wei et al. 2022) can be an artifact of metric choice; softened the strong-emergence framing that LLM behaviors appear entirely outside training encoding to note the debate over whether they are novel properties or smoothly acquired skills; and qualified urban scaling laws as broadly similar statistical regularities with notable exceptions rather than a universal invariant mechanism. The point that cities are not centrally designed was retained as a valid emergence example.

   What the page claimed

   The article stated a fixed 15% superlinear output gain, near-textbook Wikipedia accuracy, an abrupt jump to near-human LLM abilities (Wei), LLM behaviors appearing outside training encoding, and universal invariant urban scaling laws.

   What was corrected

   Scoped the scaling figure to an average exponent, qualified the Wikipedia accuracy with the 2005 Nature comparison, added the Schaeffer 2023 mirage critique, and framed urban scaling as statistical with exceptions.

   Why: The underlying research (Bettencourt/West scaling, the 2005 Nature Wikipedia study, Wei et al. 2022) is genuine but was overstated. Corrections scope the claims and add the relevant counter-evidence rather than adding unverified sources.
