We must strive always to get a rich variation of voices into our work. This means avoiding dependence on the same academics or public figures for reactions to stories. We all must look for new specialists—especially women, younger people, unconventional thinkers and people who aren’t routinely quoted by us and other media outlets, but who constitute a large part of our readership, and of the general population. This won’t happen unless we make an effort. Reporters need to expand their universe of sources.
