Strange article, starts with a long story about Jim Smith, then has some actual information, then intersperses more bits of information with the opinions of Jim.
There are no doubt countless academic papers and government reports to read if you prefer something a little drier. As it is an article on the Guardian, I got what I was expecting, more or less.
