Four Samsung Galaxy Fold review units in the hands of major US tech journalists all experienced device-breaking display failures today. AndroidPolice: Steve Kovach of CNBC, Mark Gurman of Bloomberg, and Dieter Bohn of The Verge have reported major failures of their phones' display panels, just two days after receiving them. To say this is a disaster for Samsung is probably underselling it. Well-known YouTuber MKBHD claims to be having similar problems, but hasn't posted any images. Bohn and Kovach claim their displays failed without removing the panel's protective film (Samsung says not to take it off), but both Gurman and Brownlee did. The company has yet to begin shipping the device to consumers. So far it has only handed the phone to select journalists, most of whom reported issue with it today.

Alibaba founder Jack Ma fired a shot at the United States in an interview at the World Economic Forum in Davos, Switzerland. An anonymous reader shares a report: Ma was asked by CNBC's Andrew Ross Sorkin about the U.S. economy in relation to China, since President-elect Donald Trump has been talking about imposing new tariffs on Chinese imports. Ma says blaming China for any economic issues in the U.S. is misguided. If America is looking to blame anyone, Ma said, it should blame itself. "It's not that other countries steal jobs from you guys," Ma said. "It's your strategy. Distribute the money and things in a proper way." He said the U.S. has wasted over $14 trillion in fighting wars over the past 30 years rather than investing in infrastructure at home.

To be sure, Ma is not the only critic of the costly U.S. policies of waging war against terrorism and other enemies outside the homeland. Still, Ma said this was the reason America's economic growth had weakened, not China's supposed theft of jobs. In fact, Ma called outsourcing a "wonderful" and "perfect" strategy. "The American multinational companies made millions and millions of dollars from globalization," Ma said. "The past 30 years, IBM, Cisco, Microsoft, they've made tens of millions -- the profits they've made are much more than the four Chinese banks put together. ... But where did the money go?"

An anonymous reader quotes a report from Business Insider: In a small recent study, researchers from New York University found that those who considered themselves in higher classes looked at people who walked past them less than those who said they were in a lower class did. The results were published in the journal of the Association for Psychological Science. According to Pia Dietze, a social psychology doctoral student at NYU and a lead author of the study, previous research has shown that people from different social classes vary in how they tend to behave towards other people. So, she wanted to shed some light on where such behaviors could have originated. The research was divided into three separate studies. For the first, Dietze and NYU psychology lab director Professor Eric Knowles asked 61 volunteers to walk along the street for one block while wearing Google Glass to record everything they looked at. These people were also asked to identify themselves as from a particular social class: either poor, working class, middle class, upper middle class, or upper class. An independent group watched the recordings and made note of the various people and things each Glass wearer looked at and for how long. The results showed that class identification, or what class each person said they belonged to, had an impact on how long they looked at the people who walked past them. During Study 2, participants viewed street scenes while the team tracked their eye movements. Again, higher class was associated with reduced attention to people in the images. For the third and final study, the results suggested that this difference could stem from the way the brain works, rather than being a deliberate decision. Close to 400 participants took part in an online test where they had to look at alternating pairs of images, each containing a different face and five objects. Whereas higher class participants took longer to notice when the face was different in the alternate image compared to lower classes, the amount of time it took to detect the change of objects did not differ between them. The team reached the conclusion that faces seem to be more effective in grabbing the attention of individuals who come from relatively lower class backgrounds.
