Is it true that up to half of people have no inner monologue? I investigated | Arwa Mahdawi

Our brains are miraculous and weird things, and it turns out everyone has different ways of processing the world

Sometimes I like to start a column by asking myself: should this really be a column that will live on the internet forever, for all and sundry to see? Or is this really an airing of my many neuroses that is better shared privately, with a therapist?

Not infrequently the answer is the latter. But therapy is expensive and comment is free, so I'm afraid, dear reader, that you're going to have to be my shrink today. And I'll get straight into my issues: I have a voice in my head that won't shut up.
