Rich people really do ignore you when they walk by: Study

October 25, 2016

New York, Oct 24: Wealthy people pay less attention to those around them as compared to people of lower social status, according to a new study that used Google Glass headsets to track gazes.

richThe research shows that people who categorise themselves as being in a relatively high social class spend less time looking at passersby compared with those who are not as well off, a difference that seems to stem from spontaneous processes related to perception and attention.

"Our research documents that other humans are more likely to capture the attention of lower-class individuals than the attention of higher-class individuals," said psychological scientist Pia Dietze of New York University.

"Like other cultural groups, social class affects information processing in a pervasive and spontaneous manner," said Dietze.

Dietze and co-author Eric Knowles hypothesised that our social class affects how relevant others are to us in terms of our own goals and motivations.

Compared with people who come from less-advantaged circumstances, people from relatively privileged backgrounds are likely to be less dependent on others socially; as such, they are less likely to view other people as potentially rewarding, threatening or otherwise worth paying attention.

Dietze and Knowles said this difference in what they call "motivational relevance" is so fundamental that it manifests in basic cognitive processes - like visual attention - that operate quickly and involuntarily.

In one study, the researchers had 61 pedestrians in New York City wear Google Glass, presumably as a test of the electronic eyewear.

The participants walked roughly one block while Google Glass recorded whatever they were looking at, and they also completed several survey measures that gauged social class.

In one measure, for example, participants categorised themselves as belonging to either the poor, the working class, the middle class, the upper-middle class, or the upper class.

Later, an independent group of raters watched the recordings and noted the various people and things each Glass wearer looked at and for how long.

Researchers then examined whether there were any links between what the participants paid attention to and their social class, taking participants' ethnicity into account.

The results indicate that social class did not seem to play a role in how many times Glass wearers looked at other people.

However, social class was associated with how much time they spent looking at passersby: Participants who categorised themselves as being in a higher social class spent less time looking at other people than those who placed themselves in a lower social class.

Two follow-up studies using more precise eye tracking technology showed similar results: Higher-class participants spent less time looking at people in a street scene than did their lower-class peers.

US dictionary Merriam-Webster will update the meaning of the word "racism" after being contacted by a Missouri black woman, who claimed the current definition fell short of including the systematic oppression of people of colour, according to media reports.

"A revision to the entry for racism is now being drafted to be added to the dictionary soon, and we are also planning to revise the entries of other words that are related to racism or have racial connotations," according to a statement of the 189-year-old dictionary shared by Kennedy Mitchum, a recent graduate of Drake University in Iowa, on her Facebook.

Mitchum, 22, emailed the dictionary last month, following the death of African American George Floyd in the custody of four Minneapolis police officers, Xinhua news agency reported.

"I kept having to tell them that definition is not representative of what is actually happening in the world," Mitchum told CNN. "The way that racism occurs in real life is not just prejudice, it's the systemic racism that is happening for a lot of black Americans."

Merriam-Webster's first definition of racism is "a belief that race is the primary determinant of human traits and capacities and that racial differences produce an inherent superiority of a particular race."

"It's not just disliking someone because of their race," Mitchum wrote in a Facebook post on Friday. "This current fight we are in is evidence of that, lives are at stake because of the systems of oppression that go hand-in-hand with racism."

Facebook will introduce a new notification screen on its platform that will warn users if the article they are about to share is over 90 days old, the company announced on Thursday.

“We’re starting to globally roll out a notification screen that will let people know when news articles they are about to share are more than 90 days old,” Facebook wrote in a blog post.

The social media platform had previously introduced a context button in 2018 that provides information about the sources of articles in the News Feed. Building upon that, the new feature will inform users about the timeliness of the article.

“To ensure people have the context they need to make informed decisions about what to share on Facebook, the notification screen will appear when people click the share button on articles older than 90 days, but will allow people to continue sharing if they decide an article is still relevant,” Facebook said.

The social media giant stated that timeliness is important in understanding the context of an article and curbing the spread of misinformation on the platform.

“News publishers, in particular, have expressed concerns about older stories being shared on social media as current news, which can misconstrue the state of current events. Some news publishers have already taken steps to address this on their own websites by prominently labelling older articles to prevent outdated news from being used in misleading ways,” Facebook added.

Apart from this, the platform will also be testing a similar notification screen for information related to the global Covid-19 pandemic. The notification screen will provide information about the source of the link shared in a post if the link is related to information on Covid-19. It will also direct people to its previously introduced Covid-19 information centre for “authoritative” health information, it said.

Melbourne, Jul 24: Home-made cloth face masks may need a minimum of two layers, and preferably three, to prevent the dispersal of viral droplets associated with Covid-19, according to a study.

Researchers, including those from the University of New South Wales in Australia, noted that viral droplets are generated by those infected with the novel coronavirus when they cough, sneeze, or speak.

As face masks have been proven to protect healthy people from inhaling infectious droplets as well as reducing the spread from those who are already infected, several types of material have been suggested for these, but based on little or no evidence of how well they work, the scientists said.

In the current study, published in the journal Thorax, the researchers compared the effectiveness of single and double-layer cloth face coverings with a surgical face mask (Bao Thach) at reducing droplet spread.

They said the single layer covering was made from a folded piece of cotton T shirt and hair ties, and the double layer covering was made using the sew method described by the US Centers for Disease Control and Prevention (CDC).

The scientists used a tailored LED lighting system and a high-speed camera to film the dispersal of airborne droplets produced by a healthy person with no respiratory infection, during speaking, coughing, and sneezing while wearing each type of mask.

Their analysis showed that the surgical face mask was the most effective at reducing airborne droplet dispersal, although even a single layer cloth face covering reduced the droplet spread from speaking.

But the study noted that a double layer covering was better than a single layer in reducing the droplet spread from coughing and sneezing.

According to the researchers, the effectiveness of cloth face masks is dependent on the number of layers of the covering, the type of material used, design, fit as well as the frequency of washing.

Based on their observations, they said a home made cloth mask with at least two layers is preferable to a single layer mask.

"Guidelines on home-made cloth masks should stipulate multiple layers," the scientists said, adding that there is a need for more research to inform safer cloth mask design.
