So, this morning there was a news story that someone had put together a list of the states in order of happiness, using some "16 secret herbs and spices".
The researchers might have actually known what they are doing, but once something like this enters the popular media and some people will accept it, and turn it into popular legend. This is particularly true because the list seemed to show that some rural, conservative states were the happiest while some urban, liberal states were the unhappiest. (Oregon was the 30th on the list).
So, I decided to do what I usually do: scatterplot! I decided to compare the states' happiness to their suicide rate. And this is what I got:

The states on the left are the "happiest", and the states going upward have the highest suicide rate. As can be seen, some of the "happiest" states have the highest suicide rates, and some of the "unhappiest" have the lowest. New York, for example, is the "unhappiest", but also has the lowest suicide rate. (Oregon is unhappy, with lots of suicide, so it actually fits in with something).
Although, I don't think my debunking will penetrate very far: this list will probably be repeated endlessly as a piece of folk wisdom anyway, especially to prove that good, rural, traditional folk are way happier than those neurotic coastal liberals.
