This was roughly the process that awaited me at Harper’s: every day for three months, I sat with three other young journalists, meticulously researching sentences that would appear in the upcoming issue. Once we had investigated a fact to satisfaction, we pored over our work with an imperious senior editor, who would interrogate us about nuances and details. I was thrilled by the rigour of the process. When our work was done, the published product would be empirically incontestable. Over the next few years, I worked as a freelance fact checker for various publications, and I eventually became head of research at The Walrus for two years, until 2019—a job in which I took on a similar role to that of the imperious Harper’s editor.
