Kate Devitt has done some interesting work to improve upon Google Scholar’s journal rankings, creating two different measures. Google’s ranking is skewed because it doesn’t control for the number of articles published, so quantity can trump quality. See what she’s done here and here.
Delightfully, the BJPS has done well out of this, coming in at number three and number seven, respectively, and is the highest ranking philosophy of science journal on both measures. Bask in our glamour!
