Here’s what I’ve learned, and why I did it. In December 2015, I wrote a story about the potential uses of the gene-editing technology known as CRISPR. That piece, based on a conference that I attended in Washington, D.C., quoted six men and one woman. The six men included five scientists and one historian, all quoted for their professional expertise. The one woman was a communications director at a tissue bank organization, and her quote was about her experience as the mother of a child with a genetic disease. These disparities, both in the absolute numbers of men and women, and the ways in which their quotes were used, leapt out at me, but only after the piece was published. They felt all the more egregious because the CRISPR field is hardly short of excellent, prominent female scientists. Indeed, two of the technique’s pioneers, Emmanuelle Charpentier and Jennifer Doudna, are women, and both of them spoke at the same conference from which I reported. And yet, if you read my piece, you could be forgiven for thinking that CRISPR was almost entirely the work of men.
