Here’s an interesting detail from the 4th Estate Project, a group that uses data to monitor media trends. The project amassed oodles of numbers from coverage of the 2012 elections.
As you can read here, men were used as expert sources far more often than women. But, when the researchers focused on stories from National Public Radio, they found something interesting:
There was a huge discrepancy in the sourcing patterns between men and women journalists at NPR… While men NPR journalists quoted men 80% of the time and women 20% of the time, women NPR journalists quoted men 52% of the time and women 48% of the time. This is a dramatic difference, and suggests that NPR women journalists are doing their part in trying to change the culture of sourcing in new stories. Interestingly, NPR women journalists stand out in this regard as compared to their counterparts in print or broadcast. We did not see the same discrepancy when looking at the sourcing patterns of men and women journalists working in either print or broadcast.
