I have two reasons for showing you this picture, illustrating the decline in cigarette sales in Germany, France, Japan, Switzerland and the US over the past few decades. First, to show you the decline in cigarette sales in Germany, France, Japan, Switzerland and the US over the past few decades.
Second, to encourage those of you who like pictures like this to follow Max Roser on Twitter – @MaxCRoser . His twitter feed is chock-full of wonderful pictures like this. You will probably see some of them in my twitter stream, too, because these pictures deserve to be widely shared. But if you don’t want to miss any, I suggest you go right to the source.
Sometimes when I disagree with friends or family about contentious issues, and they accuse me of being partisan, I try to defend myself by explaining that I am basing my position on science, not politics. According to a recent poll, my defense is flawed, because it seems that science itself is partisan. Across a relatively wide range of issues, Republicans are less likely to follow scientific advice than Democrats, even on some issues I wouldn’t have guessed – like animal testing for medical research, and producing biotech food and crops. Here’s a picture showing these attitudes:
In short, far too many people on both the left and the right don’t have enough trust in science. The problem seems to be especially large among people who identify as Republicans.
This study came out a while ago, from ICYMI. The research team called up primary care practices and tried to make appointments for Medicaid patients. When states raised reimbursement rates, it became easier:
Health insurance doesn’t do much good when patients can’t find doctors willing to accept crappy reimbursement.
Here is Eisenhower drawing out the connection between science and liberty:
“Love of liberty means the guarding of every resource that makes freedom possible—from the sanctity of our families and the wealth of our soil to the genius of our scientists.”
I would love to see a presidential candidate pick up this theme.
People are correctly paying a great deal of attention to just how many calories it is possible to consume at American restaurants these days. The New York Times, in fact, recently showed just how many calories people typically consume at Chipotle:
But as the folks at Vox pointed out in a follow-up post, in focusing our attention on those calorie packed entrées, we shouldn’t forget about another very important source of calories – snacks! In fact, according to one study, by David Cutler, it is snack calories that changed the most in the US between 1977 in 1996:
Does anybody have any more recent data than this? With so many more people eating out for meals now, I wonder how this has changed.
Heuristics is jargon used by decision psychologists and behavioral economists to refer to cognitive shortcuts we humans take to make judgments and decisions. One of the first heuristics identified as such by Danny Kahneman and Amos Tversky was the anchoring heuristic. I would define it for you, but it is wonderfully captured in this cartoon:
Do you think it is safe to eat genetically modified foods? I do, because I believe that most foods we eat have been genetically modified. Cows wouldn’t be cows if humans hadn’t changed them genetically, through breeding practices. That also might be because I’m a scientist, and one of the beliefs that separates scientists from laypeople’s belief is whether genetically modified foods are harmful. Here is a list of other beliefs, from a Pew Center pole:
In the United States, the FDA tried to mandate that cigarette companies put nasty images of the harms of smoking onto cigarette packages, images that would take up at least half of the carton. It looks like that effort has failed, because the courts have determined that it violates the First Amendment. I wonder what the courts will think about this graphic image, which somebody painted onto the ceiling of a “smoker’s room”.
That’s got to give people reason for pause.
With so much recent news about airplane disasters, it’s easy to become frightened about flying. I wonder if a risk graphic like the following will do much to help?
As reported on recently in The Economist, the risk graphic comes from a new iPhone app called Am I Going Down?
I’m skeptical this will work. But I still love the way their display puts this risk information into a context we can all relate to. Hurrah!
Gerald Ashley (twitter handle @Gerald_Ashley) recently tweeted a photo of what was SUPPOSED to be a helpful nudge, reducing the odds that people would bump into each other going up and down the stairs. Can you see what might not be helpful here?
