en.wikipedia.org/wiki/Sudo
- This is too absolute: sudo access does not require membership in a special group. The sudo policy can authorize individual users directly, or groups, via the sudoers policy.

- NCES data show K–12 administrative staffing did not 'barely budge.' School district administrative staff roughly doubled from 78,784 in 1980 to 155,273 in 2015.
- This overstates the evidence. NCES/NAEP data show several major national reading and math scores improved over the long term, rather than staying flat overall.

- This is too broad: some biblical prophets did hold privileged court positions. Daniel is explicitly called a prophet in Matthew 24:15, and the Book of Daniel says he was promoted, given many gifts, made ruler over Babylon, and remained in the king’s court.

en.wikipedia.org/wiki/Wiz,_Inc.
- The dates and investor details are wrong. Wiz announced the $130 million round on March 22, 2021, not April, and said it was led by Advent International with Greenoaks; the extra $120 million closed in June 2021, not May, from Salesforce Ventures and Blackstone with Aglaé Ventures.
- Wiz's own Series C announcement says the round was co-led by Insight Partners and Greenoaks Capital, not led by Greenoaks alone.

- The CRADL study was not a study of “more than 200 premature infants.” The published multicenter study enrolled 200 patients ranging from 25 weeks postmenstrual age to 36 months, including neonates and young children, for monitoring up to 72 hours.

- That is too absolute. Standard electrical impedance tomography often uses contact electrodes, but contactless impedance and dielectric spectroscopy methods also exist using capacitive coupling.

- The cited follistatin gene-therapy study was done in adult rats, not mice. Its abstract says adenoviral follistatin enlarged the livers of adult male rats to 146% of control without significant dysfunction.
- The cited Yap/Taz knockout paper reported liver adenomas, not liver cancers. It explicitly says the mice did not have hepatocellular carcinoma or cholangiocarcinoma.
- This is too categorical: human studies do report larger kidneys in obesity, and studies also report larger liver volumes in obese patients. So big livers/kidneys are not unique to athletes.
- The cited IL-6 hepatomegaly paper was done in mice, not rats. Its title and abstract both describe systemic IL-6 administration causing liver enlargement in nude mice.

- This mixes up two different eras of CFF funding. The first CF drugs were approved before the Foundation adopted its venture-philanthropy model in 1998–2000.
- AT&T was dominant, but it was not the only U.S. telephone provider. Thousands of independent telephone companies operated in the early 1900s.

- This overstates South Korea’s annual shipbuilding output. Recent South Korean output is about 21.2 million DWT, while U.S. World War II merchant shipbuilding totaled over 56 million deadweight tons.
- Recent U.S. steel output is well below 100 million tons. Major industry and government sources put it around 80–88 million tons per year, not above 100 million.

- This overstates what economics allows. Standard economic game theory explicitly studies credible threats, non-credible threats, and commitment strategies.
- Bargaining theory has in fact studied threat incentives directly. Mainstream bargaining texts and journal articles explicitly analyze commitment tactics, threats, promises, and outside options.

en.wikipedia.org/wiki/Buspirone
- Buspirone’s official contraindications do not include metabolic acidosis or diabetes. Current FDA labeling lists hypersensitivity and MAOI-related use, not metabolic acidosis.
- Buspirone-related patents predate 1980. A U.S. patent covering buspirone-class compounds was filed in 1969 and published in 1973; the 1980/1981 patent was for a later buspirone process, not the first patenting of buspirone.

- This mixes up two different quantities. In the classic Ellsberg urn, the known probability is 1/3 for drawing red; under a uniform prior over black-ball counts, the expected probability of drawing black is also 1/3, not 1/2.
- For the growth-rate formula given just above, Jensen’s inequality does not produce a strict gap. That formula is affine in p, so averaging over p gives equality: E[g(p)] = g(E[p]).
- This conclusion is mathematically wrong for the growth formula given in the post. For that formula, averaging over urn compositions gives the same value as plugging in the average probability, not a strictly smaller one; and in the classic Ellsberg setup the known probability is 1/3, not 1/2.

- The parenthetical time conversion is wrong. The story was posted at 1:48 p.m. in Texas, and on February 12, 2006 Texas was still on Central Standard Time, so that corresponds to 19:48 UTC, not 07:48.

- Reporting on the incident says Coinbase did provide AI-adoption support, including company-paid coding-tool licenses, planned training, and recurring internal AI seminars.
- The 'product engineer' role did not originate with Perplexity; Asana was publicly describing software 'product engineers' doing cross-functional product-and-engineering work by 2016.
- The Whitehall research did not show that job control is the single strongest predictor of mortality overall. It found mortality gradients by employment grade, and later found low job control was one important contributor to a narrower coronary-heart-disease gradient.
- Armstrong did not fire everyone who had not onboarded. Reporting says some employees at the Saturday meeting gave valid reasons, and only some without a good reason were fired.
