"The photographs of celebrities and models in fashion advertisements and magazines are routinely buffed with a helping of digital polish. The retouching can be slight - colors brightened, a stray hair put in place, a pimple healed. Or it can be drastic - shedding 10 or 20 pounds, adding a few inches in height and erasing all wrinkles and blemishes, done using Adobe's Photoshop software, the photo retoucher's magic wand. "Fix one thing, then another and pretty soon you end up with Barbie," said Hany Farid, a professor of computer science and a digital forensics expert at Dartmouth. And that is a problem, feminist legislators in France, Britain and Norway say, and they want digitally altered photos to be labeled. In June, the American Medical Association adopted a policy on body image and advertising that urged advertisers and others to "discourage the altering of photographs in a manner that could promote unrealistic expectations of appropriate body image." Dr. Farid said he became intrigued by the problem after reading about the photo-labeling proposals in Europe. Categorizing photos as either altered or not altered seemed too blunt an approach, he said. Dr. Farid and Eric Kee, a Ph.D. student in computer science at Dartmouth, are proposing a software tool for measuring how much fashion and beauty photos have been altered, a 1-to-5 scale that distinguishes the infinitesimal from the fantastic. Their research is being published this week in a scholarly journal, The Proceedings of the National Academy of Sciences. "

"Andrew Pole had just started working as a statistician for Target in 2002, when two colleagues from the marketing department stopped by his desk to ask an odd question: "If we wanted to figure out if a customer is pregnant, even if she didn't want us to know, can you do that?

Post a Comment » Read All Comments (35) » Pole has a master's degree in statistics and another in economics, and has been obsessed with the intersection of data and human behavior most of his life. His parents were teachers in North Dakota, and while other kids were going to 4-H, Pole was doing algebra and writing computer programs. "The stereotype of a math nerd is true," he told me when I spoke with him last year. "I kind of like going out and evangelizing analytics." As the marketers explained to Pole - and as Pole later explained to me, back when we were still speaking and before Target told him to stop - new parents are a retailer's holy grail. Most shoppers don't buy everything they need at one store. Instead, they buy groceries at the grocery store and toys at the toy store, and they visit Target only when they need certain items they associate with Target - cleaning supplies, say, or new socks or a six-month supply of toilet paper. But Target sells everything from milk to stuffed animals to lawn furniture to electronics, so one of the company's primary goals is convincing customers that the only store they need is Target. But it's a tough message to get across, even with the most ingenious ad campaigns, because once consumers' shopping habits are ingrained, it's incredibly difficult to change them. There are, however, some brief periods in a person's life when old routines fall apart and

Part 1 of a 4-part series examining what happens when science is used for marketing (using brain-training software as the central example). Almost all of the programs that tout their ability to train your brain are limited in scope. Most train your ability to perform simple cognitive tasks by having you perform them repeatedly, often adapting the difficulty of the task over time to keep it challenging. Some determine which tasks you perform well and which need improvement and adjust the tasks based on your ongoing performance. The simplest ones, though, simply track how much you improve and inform you that such improvements have made increased the fitness of your brain. Such task-specific training effects can be really useful-if you want to enhance your ability to do Sudoku, by all means practice doing Sudoku. But what pitches for those programs regularly imply is that playing their videogame or using their training will enhance your ability to do other tasks that weren't specifically trained. For example, this advertisement for Nintendo's Brain Age implies that by using their game, you will be better able to remember your friend's name when you meet him on the street. The idea that playing games can improve your brain is pervasive, and it taps what Chris Chabris and I have called the "illusion of potential." A common myth of the mind is that we have vast pools of untapped mental resources that can be released with relatively minimal effort. This common intuitive belief underlies the pervasive myth that we only use 10% of our brains, that listening to Mozart can increase our IQ [pdf], and even the belief that some people have "discovered" psychic abilities. We devote the last main chapter of The Invisible Gorilla to this belief and its ramifications, and we recently wrote a column for the NY Times discussing how popular self-help books like The Secret and The Power capitalize on this mistaken belief. The marketing for some brain training programs

"It isn't often that a third of a movie audience sticks around to discuss its message, but that is the effect of "Race to Nowhere," a look at the downside of childhoods spent on résumé-building. " "How do you help your children balance when the whole education system is pushing, pushing, pushing, and you want your kids to be successful?" Alethea Lewis, a mother of two, asked a roomful of concerned parents who had just seen the film, a documentary, last week in Bronxville, N.Y., at a screening co-sponsored by the private Chapel School. With no advertising and little news media attention, "Race to Nowhere" has become a must-see movie in communities where the kindergarten-to-Harvard steeplechase is most competitive.
