Centrelink debt notices based on 'idiotic' faith in big data, IT expert says

from the article:

IT and data expert Justin Warren – who has worked for IBM, ANZ, Australia Post and Telstra, among others – said Centrelink’s system appeared to rest on the “idiotic” assumption that “big data was magic”.
“It’s not. It’s a messy, complex, statistical system that is wrong a lot,” Warren said. “All models are wrong, but some are useful. It’s the choice of how you deal with when the system is wrong that reveals how you view the world.”
