I'm trying to start playing Democracy 3, but I'm having a little difficulty with the UI. I understand that a green arrow means a positive relationship and a red arrow means a negative relationship, but what does a black arrow mean?
For example, in this screenshot:
Narcotics are currently illegal. What does it mean that Narcotics has black arrows pointed towards Legal Drug Consumption, and Legal Drug Consumption has black arrows pointing towards Health, Productivity, and Alcohol Consumption?
