Briefly

By
  • Jessica Mackenzie on the “dire” wolf story, and how it got that way: “It’s important to consider how sausage like this is made, and I mean the stories—not the actual wolves.”
  • Visualisation of the “demise of the love song” from pudding.cool
  • Proportions and totals: is the individual risk of Alzheimer’s going down over time? (apparently, yes, even though the total number of cases goes up with the number of older people)
  • Australian Associated Press fact check: Claim – 710,000 new voters on the electoral roll include migrants who arrived under Labor.  False: Migrants who arrived under Labor are not eligible to vote in the 2025 election.
  • Stuff headline: Traffic ‘worse than Auckland’: Is this New Zealand’s most ‘anti-car’ city? We’re seeing proper use of headline single quotes here — ‘worse than Auckland’ is an attributed quotation in the text. It is, however, attributed to a single motorist.  Headlines about traffic density/slowness really shouldn’t just be one person’s opinion — traffic is measurable, and measured.

ISI on US official statistics

By

The International Statistical Institute is a professional organisation of statisticians. Its membership includes quite a lot of expertise on the production and use of official statistics, and it has a habit of commenting on political interference with official statistics.

The ISI has a statement on US official statistics

The International Statistical Institute (ISI) is concerned about government interference in the compilation and availability of Federal Statistics in the United States of America (USA). A proposed change in measuring and reporting U.S. Gross Domestic Product (GDP) serves as an important and timely example.

The statement goes on to explain that the USA has proposed removing government expenditures from GDP, and that this is both intrinsically a bad idea and also a weakening of international agreements on which official statistics to measure and how to define them.

 

[Disclaimer: I’m a member of the ISI, but I wasn’t involved in any way in producing this statement]
