Suppuration posts a graph. The graph shows unusually high spending on health care and low life expectancy for the U.S.
As statisticians know, our first instinct is to assume that the x-axis has some kind of relationship to the y-axis. "My god, they're on the same graph together! They must be connected!"
As the good scientists that we presumably are, we should look further and question that assumption.
Hmmmm, Japan has the highest life expectancy. America has one of the lowest. Here's a hypothesis. What if life expectancy has more to do with personal lifestyle choices?
Japanese people eat healthy foods in moderate quantities, they exercise, etc. In America, obesity is a huge problem; we eat a lot and don't exercise.
Looking just at the countries and the life expectancies, this hypothesis seems plausible. Let's look for more data.
I found some data from the international obesity task force:
IOTF
Apparently they have compiled BMI tables for many countries:
BMI tables
Now let's see.
Japan, #1 life expectancy:
obese males = 2.9%
overweight males = 23.9%
Switzerland, #4 life expectancy:
obese males = 14.1%
overweight males = 45.9%
Canada, #10 life expectancy:
obese males = 16%
overweight males = 40%
WAIT, I'M STARTING TO SEE A TREND!
England/UK, 7th from last life expectancy:
obese males = 22.2%
overweight males = 43.2%
United States, 5th from last life expectancy:
obese males = 27.7%!!!
overweight males = 39.3%
These numbers show a general trend, with of course, fluctuations. If you took the time to plot a graph of life expectancy vs. BMI, you'd see a significant correlation.
As I mentioned before, correlation is not sufficient to imply cause, you also need a plausible causal mechanism. In this case, indeed, there is a very plausible explanation for how unhealthy lifestyles affect life expectancy.
The fact of the matter is, per capita spending has little or nothing to do with life expectancy. What really matters is healthy living.
But if healthy living would improve our situation, why are we spending all that money? If indeed proper living is responsible for improved life expectancy, then it doesn't matter how much we spend.
BINGO! We've stumbled upon something interesting. Perhaps, just perhaps, the U.S. is mistaken on dumping money into the healthcare system. We think throwing money at a problem makes it go away. The graph strongly emphasizes how WEIRD it is that we spend so much. The conclusion: politicians have been wasting our money in order to make it look like they are solving the problem, when actually, the real problem is poor living on the part of American citizens. Clearly, we are spending way too much on healthcare, just so we can ignore the real problem: that we are fat and lazy.
