On its face, one might think the case of Jo Boaler was put to rest seven years ago. But now, it is Jo Boaler herself who brings it back with her article of October 2012, cited by MPG. Interestingly, the issue Boaler raises is not her research, but her claim of persecution. From which I conclude that she gets more professional mileage from "persecution" than she gets from academic research.
By resurrecting this old canard, Jo Boaler indicts herself.
