If it is not true, it will be.
Georgina Sturge interview: “The numbers don’t count. People do” – New Statesman
An interview with Georgina Sturge, a statistician in the House of Commons Library. The first quote deals with an issue I have heard about before, although I do not know further details. If it is not true it will be.
Sturge also cites the cautionary tale of Carmen Reinhart and Kenneth Rogoff, two Harvard economists whose 2010 model purported to show that, if a country’s debt-to-GDP ratio exceeded 90 per cent, the risk of a negative impact on long-term growth became significant. This research was used by George Osborne to justify austerity, on the grounds that if the UK didn’t get its debt under control, the economy would shrink. The only problem? Reinhart and Rogoff had made an error, missing off five rows of data on their spreadsheet, negating their conclusion about the risk of negative growth. By the time this was spotted, austerity was well under way and its effects are still being felt now. And while it’s a stretch to say that David Cameron and Osborne would have pursued a different course had the mistake been caught earlier, bad data gave them cover for their economic programme.
If we want our politicians to use data more responsibly, Georgina Sturge argues, we need to invest in better ways of collecting it. It’s perverse that we know more about the performance of Premier League footballers than how many children are out of school.
Not really. It’s just money.
