One of the problems with informed consent is you have to be informed.
There was a study into improving rates bowel cancer screening uptake. What they found when people have been given greater information about the possible side effects and treatments, quality of life and whether it actually prolongs life significantly enough to be worthwhile, consent levels dropped. The data showed that unfortunately whilst patients didn't die of bowel cancer their life expectancy didn't improve and they just died of something else because their body had pretty much just gone kaput all at the same time. (Source Margaret McCartney's patient paradox).
This causes something of an ethical dilemma for authority who want to increase uptake of the screening. Greater informed consent reduced uptake.
And of course withholding such information can lead to loss of trust elsewhere.
We know that measures to increase trans access were DELIBERATELY rushed through and rushed through quietly. They did not want public scrutiny. They wanted to actively bypass public consent checks and balances.
They didn't want women to have the opportunity express their consent or withdraw consent.
And now people are more aware of what the proposals mean in practice - the bearded wanker in your workplace watching you undress in the female changing room or accusing you of transphobia when you refuse to change whilst he's still there - suddenly the penny starts to drop.
This is about clearly conveying information and being transparent with implications and discussion of possible unintended consequences.
Just saying we should be nice, doesn't cut it. It's a lack of ability to engage with a subject in its entirety and to deal with inconvenient problems.
