These attitudes, assumptions and prejudices [about women speaking in public] are hard-wired into us: not into our brains (there is no neurological reason for us to hear low-pitched voices as more authoritative than high-pitched ones); but into our culture, our language and millennia of our history. And when we are thinking about the under-representation of women in national politics, their relative muteness in the public sphere, we have to think beyond what the prime minister and his chums got up to in the Bullingdon Club, beyond the bad behaviour and blokeish culture of Westminster, beyond even family-friendly hours and childcare provision (important as those are). We have to focus on the even more fundamental issues of how we have learned to hear the contributions of women or – going back to the cartoon for a moment – on what I’d like to call the ‘Miss Triggs question’. Not just, how does she get a word in edgeways? But how can we make ourselves more aware about the processes and prejudices that make us not listen to her.
