I think it’s hard to estimate improvements in joy/happiness. I’m already generally happy, and any gains I have I will get accustomed to and then not feel the benefit as much as I did initially. Having said that, I think I was four times more joyous it would be a pathological level and not a net good to this world. Other people who are miserable and net unhappy you could massively increase their happiness by making them have a net positive emotional valence. So if you want to increase the gross joy of the world, focus exclusively on those most unhappy. This has the caveat to help those who can be helped and made to feel happy of course, and most long term impacts. Fund wells and clean water, give job opportunities, improve social care, education, surgery for people in developing countries with terrible quality of life (e.g. women in Africa with horrible labour related tears and constant incontinence- that’s awful and relatively easily treated).
