Recent findings (audit lane, verbatim)

Astragalomancy — The entry states that the two narrow sides were 'one flat and one concave, while the two broad sides were one concave and one convex.' This is incorrect; in actual astragaloi, one broad side is flat (the 'belly'), the opposite broad side is convex (the 'back')

Astragalomancy — The entry says 'the roll of five ones was associated with Zeus.' This is not a known outcome from standard Greek astragalomancy oracles; the known oracles do not include a result of five ones for Zeus, and the most famous oracle assigns that combination to a d

The Dice Man — The claim that Emmanuel Carrère revealed in 2019 that Cockcroft was a lifelong English professor, a husband of fifty years, a father of three, and a caregiver for a special-needs child is not a widely-known, established fact in the canon; Cockcroft was a write

Dice notation — The claim that dice notation 'emerged in the mid-1970s within the fan community of Dungeons & Dragons' is misleading; the notation was already in use in wargaming communities before D&D.

Dice notation — The claim that Ted Johnstone and Barry Gold independently introduced dice notation in 1975 in Alarums & Excursions is not supported by established canon; the notation predates that publication.

Four-sided die — The claim that 'In Ancient Rome, elongated four-sided dice were called tali' is incorrect; tali were knucklebones (astragali), which are irregularly shaped bones with four usable sides, not elongated four-sided dice.

Four-sided die — The claim that 'The ancient Mesopotamian Royal Game of Ur uses eight four-sided pyramid-shaped dice made of rock, half colored white and half black' is inaccurate; the game used four tetrahedral dice, typically made of clay or stone, with two corners marked an

Fuzzy dice — The claim that 'hundreds of pilots were shot down each week' during World War II is vague and potentially misleading; actual U.S. fighter pilot losses varied greatly by theater and time period, and the phrase 'hundreds each week' is not a standard historical f

Fuzzy dice — The claim that 'a 1993 study found no correlation between the use of fuzzy dice and the degree of a driver's reckless driving behavior' is unverifiable and likely invented; no widely-known, reputable study of this specific nature is documented in established a

Go First Dice — The entry states that for three players, an optimal permutation-fair solution using three 6-sided dice was found by Robert Ford in 2010, but it was actually discovered by Eric Harshbarger.

Go First Dice — The entry states that for four players, an optimal permutation-fair solution using four 12-sided dice was found by Robert Ford in 2010, but it was actually discovered by Eric Harshbarger.

Intransitive dice — The claim that the largest possible probability for a cycle with weighted dice is approximately 0.62, equal to 1 over the golden ratio, is not a standard, widely-accepted fact in the known history of intransitive dice; the known result for optimal intransitive

Juryeonggu — The original artifact was not destroyed in a microwave oven; it was damaged during a conservation attempt using a heating device, but the specific claim about a microwave oven is not supported by established historical accounts.
