You aren't wrong to be curious, but you are going to get unhelpful and emotional answers when asking about this. You should genuinely read the wikipedia page on this topic: https://en.m.wikipedia.org/wiki/Lobotomy https://en.m.wikipedia.org/wiki/Lobotomy it will answer your questions and reveal the horror of what you are asking about and why people respond the way they do. To sum up though; the procedure was mostly performed on women and children, who were also frequently not aware of what was being done to them (not consenting), on men it was mostly performed on homosexuals. The best case outcomes came at the cost of 'decreased psychic complexity', a sort of 'permanent childhood'. The worst cases don't bear repeating here. I would also like to caution you, when reading on this, note whose voice is present; is it ever the subject who reports positive outcomes?
