Are women academics less likely than their male colleagues to present themselves as experts? Shari Graydon, a former newspaper journalist who now runs a consulting firm called Informed Opinions, thinks so. Ms. Graydon runs regular on-campus workshops with academics in Canada about how to share their expertise with the public. She has surveyed hundreds of female academics and found that they are quoted in media reports far less often than men. “The skew is so significant – it’s currently about 80-20 [male to female],” says Ms. Graydon. She notes that women tend to fear that they will look presumptuous by speaking on a subject and they also prefer taking time to consider their answers – a definite impediment for television and radio broadcasts. “There’s a whole contribution and value that we’re not getting access to if they’re not sharing what they know,” she says.
