How happiness works? (answer is here)

[Grandpa Kim]

From Asmala:

Every +5% in Happiness causes -0,1% and every -5% in Happiness causes 0,1% change in anger level.

Sounds like you tested this thoroughly but that ratio sounds awfully low to me. Raising your happiness characteristic to 20% would not even come close (only.4%) to counter-acting the 2% natural anger increase of alien races. Seems modifying your your happiness upward would be a waste of points, yet it has always paid dividends for me.

Perhaps I am reading you wrong; my experience says its better than this.
