Paradox of automation
edit
The paradox of automation says that the more efficient the automated system, the more crucial the human contribution of the operators. Humans are less involved, but their involvement becomes more critical. Lisanne Bainbridge, a cognitive psychologist, identified these issues notably in her widely cited paper "Ironies of Automation."[49] If an automated system has an error, it will multiply that error until it is fixed or shut down. This is where human operators come in.[50] A fatal example of this was Air France Flight 447, where a failure of automation put the pilots into a manual situation they were not prepared for.[51]](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:byjjq67p7iau6qufzjmizpbn/bafkreie4ootzzyowpylsxjg7gxsp63iujxh4qceuuxxhwm63yrm2qffa4e@jpeg)
