[Ed. – Well, thank heavens we finally have a study on this.]
“When male journalists reply to other beltway journalists, they reply to another male journalist 91.5% of the time,” according to a study to be published in the the International Journal of Press/Politics, titled “Twitter Makes It Worse: Political Journalists, Gendered Echo Chambers, and the Amplification of Gender Bias.”
Of the 25 reporters who received the most replies from male political reporters, zero were women. …
The study also identified the 25 political reporters who male political reporters retweet the most. Of the 25, just three are women.
“We found that male journalists, indeed, were more likely to retweet other male journalists— in fact, when male journalists retweet, they retweet men almost three times more often than they retweet women.”
