This article on first principles thinking was largely well sourced and accurate, including its Tesla battery-cost example, its SpaceX example's underlying figures, and its accounts of Marshall and Warren's H. pylori discovery and Warren Buffett's investment philosophy. Two issues were found: a direct quotation attributed to chip architect Jim Keller from a specific, real, checkable interview could not be verified anywhere in that interview's actual transcript, and a cost-reduction figure for SpaceX's reusable rockets overstated the reduction relative to the article's own cited baseline.
What the page claimedThe article quoted Jim Keller directly, attributing a specific multi-sentence statement to a named 2020 Lex Fridman podcast interview, when that exact quote could not be verified against the real, publicly available transcript of that interview. It also described Falcon 9 reusability as reducing launch costs by 'roughly an order of magnitude' when measured against the $10,000 per kilogram figure the article itself had just cited, a reduction that is closer to three to four times against that specific baseline.
What was correctedThe article now describes Jim Keller's real, general views on analogical versus first-principles reasoning without an unsourced direct quotation, and describes the SpaceX cost reduction more precisely as three to four times relative to the article's own cited baseline, noting that a full order-of-magnitude reduction holds only when compared against the highest historical launch costs, such as those of the Space Shuttle.
Why: A web search for the quoted passage attributed to Jim Keller, checked directly against the real interview's transcript, found no matching text, which is a more serious issue than an ordinary statistical error since it presents unverified wording as a verbatim, checkable statement from a real, named, living person. The SpaceX figure was a defensible but generous rounding that did not match the article's own stated baseline. Both were corrected while preserving the article's otherwise accurate and well-documented examples.
