I don't think it is. In developed nations I'd guess that 0 is probably the majority (maybe 0, 1 and 2). The internet isn't the best place for these kinds of statistics. If they where everyone would be depressed, have contemplated or attempted suicide, have anxiety and a host of mental problems.
There is new research that suggests that talking about problem like depression may in fact cause depression and the internet is amazing at propagating the idea that all sorts of mental issue are something that everyone encounters.
My score was 0 and I have a happy, if middle class life and wonderful family. Stressful at times, but mostly not. It's also not terribly exciting, but that suites me.
You match me in every element, perhaps this outcome is expected for ACE 0. Or it could be confirmation bias.
Any other people with ACE 0 here? What is your life like?
