It seems that there is a lot of confusion as to how this chart works. I've encountered numerous players that are trying to figure out how to fix the concerns shown here, even when those concerns really aren't issues for their colony.
My suggestion would be to add "not concerned" or something to that effect to the pie chart. I believe much of the confusion would be eliminated if it showed something like "2% depression, 98% no concerns" rather than "2% depression, 98% fatigue" and causing many players to try and solve the issue with fatigue, or whichever concern is showing at that time...
I think what's confusing is people don't put it into perspective of how the happiness is and how the health is. Plus we mis vital information about the causes. It's hard to micromanagement if you have to speculate. So I would want a option to click on the chat and see a list of reasons. Like lack of hospitals, commute distance, lack of entertainment. Etc
