Your questions are profound but sadly I don't have profound answers to them. But I can put in my two cents for whatever they are worth. So . . . here goes . . .

Do you know the old saying . . . Bad news sells newspapers and good news is no news?"

I was in journalism. And this was the axiom for us. I could not go on national television and say this: "Today 40,000 aircraft took off and landed safely. Today 10,000 trains did not derail. Today billions of children went to school and did not commit an act of mayhem. Today 99 percent of the earth was not destroyed by an earthquake, fire or flood."

In journalism we assume that things are 90% or more okay and that exceptions are what people are interested in. It is the one crash out of 40,000 flights that people are interested in, it is one derailment, it is the one earthquake, it is that one student who today went berserk.

Evil makes the news because it is rare because good is the rule rather than the exception. Of course evil is terrible. But it is shocking because it is rare in comparison with good. Yes, today a certain number of human beings are going to commit a felony crime. But the vast majority of people on this earth are not going to do this. Many people on the earth are in prison but most [billions] are not.

So I think evil is the little sliver although 24 hour news cycles make evil seem so big.
We journalists need to make money through advertisers. And advertisers look at circulation, market share and so on.

Evil gets people tuned in, but I don't think good is a sliver.

I don't know enough about the statistics of relationships. Someone else will have to speak to that. .

If tomorrow, one trillion people go berserk and commit mayhem on the earth, and 40,000 planes crash, and 10,000 trains wreck, and almost every student in every school goes berserk, then I would be able to say goodness is a sliver in the huge plank of evil.

Now that I am out of journalism, I avoid it because I know it gives a warped view of things. Journalism can be really hard on people with mental illness since it can feed our confirmation bias.

Others here will have other opinions. I will be interested in reading them. Best wishes to you!
