Glad you've started this - I just read this article and came looking for a thread.
It's a fascinating read. There are two main points, one which comes as no surprise (the existence of a pay gap) but the second, which is more revealing, is that the pay gap is perpetuated by the very people who think "there is no pay gap."
For those who don't want to read the whole article, the researchers submitted identical CVs (indicating high competence to do the job), one with a male name and one with a female name, to veterinary practices, and asked them what sort of starting salary such a person should get. On average the male name garnered suggested offers 8% above those for the female name.
But the interesting bit was when they asked the practice managers what they thought about the pay gap.
"Those most responsible for the gap believed that gender bias no longer existed in their profession. Those who believed bias still existed recommended roughly equal pay."
I know we often say on here "if you can't see sex, you can't see sexism", but this rather suggests a neat reversal - "those who can't see sexism still see sex, and still perpetrate sexism."
