Be Very, Very Careful What You Tweet

First there was Facebook.  Then, Cambridge Analytica.  Now here comes Twitter. A  majority of Twitter users don't know that researchers often gather and study their tweets – and occasionally, even the deleted ones, according to newswise.com.
Most believe researchers should be asking for permission and wrongly assume not doing so violates Twitter's Terms of Service, says a new study by University of Kentucky Assistant Professor Nicholas Proferesand Casey Fiesler, an assistant professor at the University of Colorado Boulder. 
On the heels of the Cambridge Analytica controversy, in which 87 million Facebook users might have had their data shared with the firm, "questions abound about data, privacy and ethics on social media and beyond," reports newswise.com.
"In light of recent events, transparency is even more important," states Proferes, co-author and faculty member in the UK College of Communication and Information's School of Information Science.
By surveying 268 individuals who used public Twitter accounts, the authors also found that many users thought researchers were banned from collecting and analyzing public tweets, were surprised that deleted tweets might be used in studies; and had very strong opinions on the practice if those users were taking steps to protect their account.
Part of the problem, Proferes notes, is how social media companies neglect to explain how information flows and is used beyond users' intended audiences, newswise.com explains.
Many areas of research rely on social media data, from predicting sentiment for products to better understanding how communities respond to social events. In the study, most users thought using public social media data for science is important and would be willing to let their content be used for scientific research if they were asked.
"This raises a number of questions about how we, as researchers, should handle user content, and how we might go about informing users about research that uses their publicly available content," he asserts.
Typically, researchers are required to go through Institutional Review Board (IRB) processes when conducting research on human subjects, but these can differ among institutions. For example, some IRBs may treat research using publicly available social media data as an observational study in a public space that doesn’t require consent.

    "But is Twitter equivalent to a public park?" Proferes asks. "It's not. If I see someone observing me, I can walk away. Twitter is a one-way mirror."
    Proferes and Fiesler also found that users’ attitudes toward the practice differed depending on contextual factors, such as the topic of the research, the pool of data — one tweet or the user's entire history — and whether the tweets would be attributed or anonymous.
    "Twitter is a really rich source of data for scientists to understand social phenomena," Proferes said. "But we can do better about informing people about our research, getting their permission when possible and sharing our findings."

    Ever Make a Bad Choice? Make it Worse by Rationalizing It?

    I knew it was probably a risky thing to do.  But I hadn't been paid, and kept getting the runaround, so when I went over my boss's head, and his boss told me he'd look into it the following week, what I'd been hearing all along, I kind of went a little nuts and said, "Please don't take this the wrong way but I feel like I'm getting the runaround again." And, poof!  They fired me. So how do we talk ourselves into rationalizing bad choices ? I had every right to get paid.  But most likely I should have known the guy had a thin skin and I should have been more careful.  Even my son, 16 at the time, told me I should have not done it. "When a reward is tempting enough, people will break their own moral codes to gain the desired prize," says newswise.com. "Afterward, they’ll tell you exactly how they were justified: 'It wasn’t as if anyone was harmed,' “I was only borrowing …,” 'My boss told me too,' or 'It’s our ...

    Happy? Stay Away From Others, Say Experts

    This may sound very strange but a new study says people protect their good moods to stay safe. What's that again? " Once happy, steer clear of choices that could invite in negative feelings," says newswise.com, quoting  Heath Demaree , professor and chair of the  Department of Psychological Sciences  in the  College of Arts and Sciences  at Case Western Reserve. “They wonder: How much better does it get? If you’re already happy, why risk making your mood worse?” says Demaree, co-author of the study, published in the journal  Frontiers of Psychology . “Essentially, it’s quitting while you’re ahead.” "The findings differ from some previous research, which has shown that a person’s risk-taking increases after they’ve become successful—known as the 'house money' theory. Still, other studies suggest that people risk more when they’re losing, hoping to break even," newswise writes. I don't know about you but when I'm happy, I want to shar...

    Does the 'Nudge Factor' Influence Your Decision-Making?

    I'm not much of a gambler.    Because it has had quite a negative impact on my family (my grandfather went to jail for it back in the 1920's), I've stayed away from it. But now a new study suggests why some people hold them, and others fold 'em. Why do people make high-risk choices – not only in casinos, but also in other aspects of their lives – even when they know the odds are stacked against them? A team led by a Johns Hopkins biomedical engineer has researched why some people make high-risk choices – not only in casinos, but also in other aspects of their lives – even when they know the odds are stacked against them, according to newswise.com. Scientists found that "the decision to 'up the ante ' even in the face of long odds is the result of an internal bias that adds up over time and involves a 'push-pull' dynamic between the brain’s two hemispheres ," the web site reports. Whether you are suffering from a losing streak or rid...
