Who else's fault would it be?
If a girl becomes anorexic, is it her fault?
I certainly don't approve of shaming; it's a form of bullying.
On the other hand, I don't approve of enabling either..
That's a hard needle to thread and I think for public health purposes personal blame is unhelpful. What happens a lot is that some problems are "overdetermined." U.S. food manufacturers spend a lot of money figuring out how to get people to overeat. Now imagine that some people are genetically more predisposed to overeat than others, or have slower metabolisms, or are shorter. They are overdetermined to get fat. Either fact alone is a risk factor; taken together they become a near certainty. Certain Indian nations are highly prone to Type 2 diabetes. A genetic predisposition + risk factor = lots of suffering. If only they had some self-control ... but maybe it had something to do with living off Army rations of flour, salt and lard. You get a delicious metabolical disaster. Add alcohol, make it worse.
Other industries will push skeletal human clothes hangers as the epitome of attractive and teenage girls will starve themselves, sometimes to death. Why does this happen to some girls and not others? Is
agency involved at all? All they have to do to save themselves is
eat. But it's horrific to them. They will imagine themselves grossly obese when everyone else can see they're dangerously underweight. It doesn't happen to all young girls; but there might be patterns as far as who's at risk.
Freddie Mercury's death was his own fault. Or was it? There happened to be a brief period in history when the consequences of promiscuity were somewhat manageable (post-penicillin, post-Pill, pre-AIDS) and quite a few people fatally misjudged the finer points of viral epidemiology.
Thousands of people are "ejected" from cars every year; it's their own fault they weren't wearing a seat belt.
Many emergency room visits would be unnecessary if people refrained from patently stupid behavior.
Many problems in public health have a behavioral component, but often levels of risk involve other factors that are out of an individual's personal control. IMO the "blame game" is ... simplistic? Unhelpful? Counterproductive?
Let me give an example.
I'm not saying my sister is Mary Poppins but my nephews get fizzy drink and McDonald's only as a treat at someone's birthday party.
Fish and chips is the odd one they get every couple of weeks.
I totally get that public health problems are often the result of ill-advised choices. But there are other factors too. If a family is relying on McDonalds for supper and that becomes a pattern, then behavior gets more entrenched. A shocking number of people don't know that "fat-free" foods can make you FAT. They don't know that putting ranch dressing all over their salads makes calorie content soar. I tend to think Americans are more ignorant than people in other countries, though I don't know that for a fact. Partly it is not wanting to walk 10 steps if it can be avoided, lift anything heavy if it can be avoided, get up to change the channel if it can be avoided (we get our exercise looking for the remote!). It might just be easier in the U.S. to avoid walking. Put everything at the scale of automobiles, create drive-in windows and attached garages, and we barely have to move at all.
This Washington Post account may be
superficial and oversimplified, but it does illustrate what I'm talking about. The way societies are designed, or evolve, carries impacts down to the individual level, so that individual responsibility is partially eclipsed by larger changes in the environment.
