When I was young, people generally submitted to every sort of authority figure. Be they doctors, teachers, parents, government ministers, civil servants or police officers, we did what they asked us to do because obviously we were ignorant young dimwits and they were older and wiser.
That attitude slowly caved in and people started to question authority figures and the idea that they knew best. Did they really know best or were they fallible individuals who could get things horribly wrong as well as totally right?
Confidence in experts has been shaken by a constant succession of disasters and blunders. Like the inferno at Grenfell Tower, which was covered in inflammable cladding. Like incompetent surgeons who leave patients in agony. Like houses that are knowingly built on flood plains.
Bit by bit automatic respect for authority figures has drained away as people got the confidence to challenge what they said. And quite right too. Instead of assuming they won't be questioned, they have to justify their opinions and take people's scepticism into account.
That questioning can be overdone of course. Those people who say they never trust an expert and rely on their own judgment are taking distrust too far. They're often grossly misinformed and horribly wrong themselves.
We need a happy medium where the opinions of experts aren't instantly dismissed but carefully examined and evaluated before we rely on them.
