The proverb "ignorance is bliss" is used to express that somebody feels better by not knowing all the details about a topic.
In an existing thread titled "ignorance is not bliss", it is claimed that an example of the opposite of "ignorance is bliss" is the discovery of a brain tumor, which, while devastating, allows starting the necessary life-saving treatment. In other words: ignorance is worse. Arguably, however, this is not the opposite of "ignorance is bliss" at all: when the cancer patient was ignorant, he was certainly much happier than when he found out about his life-threatening condition. Sure, it is better to know the details in that situation, but that doesn't mean it feels better, which is exactly the point made with the proverb "ignorance is bliss".
I'm looking for the actual opposite of this proverb, namely that it feels better to know more details, or even that it feels worse not to know all the details.
This can be applied to several contexts:
- Sometimes people overthink and over-worry about hypotheticals, and in such cases they are better served knowing the full story.
- Technological doomspellers claim that artificial intelligence will soon destroy the world. Yet, being a researcher in artificial intelligence myself, I am a lot less worried about this knowing the details of what is and isn't feasible. The opposite of "ignorance is bliss" is again more applicable here, since those who have a vaguer idea about the situation sleep worse at night, not better.
Does such an opposite exist in another proverb? If not, is there a common change English natives make to the proverb to flip the meaning (e.g. "ignorance is worry")?
