Tests have placed me in the top 1% of intelligence - I am also a very very happy person. I have a lot of friends who score in the same range on such tests - most of them are happy, but for a lot of them it took a long time to get there. I think intelligent people find happiness in different ways than most, and they need to find their own way - that might be difficult.

On the contrary. The middle class in the netherlands are continiously bitching about everything the think is done to them on purpose, like vaccins, maroccans, crisis, etc. Intelligent people are mostly happy people until a half dumb person comes pissing them off. It's the dumb people that pollute the most, socially as well as environmentally.

Just proves that old saying "Ignorance is bliss", might be that if you dont know about the certain issues with starvation in the world, poor living conditions, environment going to hell, etc etc you can go about your life without a care. OR the fact that an intelligent person has poor social skills. IE some of the prodigal children who loss it after a certain age. There are ALWAYS exceptions to the rules.

Smart people may be more cynical. Does cynicism destroy happiness or is it a construct to preserve happiness? If you are smart you have the keys for control of your life. This, it seems to me, is a prerequisite for happiness. Unless you are bipolar.
