I was recently scheduled to present my Cautionary Tales podcast live on stage as a curtainraiser for a podcast conference. Talented voice actors, live sound effects and even a trombone would weave a dramatic soundscape for a full house. There was only one problem. Nobody seemed to have the authority to let me in.

The people issuing conference passes wouldn’t give me one — not unreasonably, since I wasn’t attending the conference proper and hadn’t registered to do so. They advised that I speak to “that lady there”. That lady there seemed puzzled: the conference wouldn’t officially open until tomorrow, so I didn’t need a pass. Just walk in, she said. The security guard had a different view. He had been given strict instructions that nobody gets in without a pass. Talk to the conference team, he told me. Nothing to do with us, they said — talk to security.

I realised I was facing what the writer Dan Davies has named an “accountability sink”, in which it was somehow nobody’s fault. In his recent book The Unaccountability Machine, Davies explains the basic logic of an accountability sink: decision-making power is removed from individuals you might want to shout at, and made instead by an algorithm or some distant committee both ignorant of and immune to your objections.
