According to a new study published in the Proceedings of the National of Sciences (PNAS), computer predictions based on a generic digital footprint (Facebook Likes) are more accurate (r = 0.56) than those made by the participants’ Facebook friends using a personality questionnaire (r = 0.49); (ii) computer models show higher interjudge agreement; and (iii) computer personality judgments have higher external validity when predicting life outcomes such as substance use, political attitudes, and physical health; for some outcomes, they even outperform the self-rated personality score.
The authors point out that “perceiving and judging other people’s personality traits is an essential component of social living. People use personality judgments to make day-to-day decisions and long-term plans in their personal and professional lives, such as whom to befriend, marry, trust, hire, or elect as president. The more accurate the judgment, the better the decision. Previous research has shown that people are fairly good at judging each other’s personalities; for example, even complete strangers can make valid personality judgments after watching a short video presenting a sample of behavior.”
This study compares the accuracy of personality judgment— a ubiquitous and important social-cognitive activity—between computer models and humans. Using several criteria, the researchers demonstrate that computers’ judgments of people’s personalities based on their digital footprints are more accurate and valid than judgments made by their close others or acquaintances (friends,family, spouse, colleagues, etc.). Our findings highlight that people’s personalities can be predicted automatically and without involving human social-cognitive skills.
Smartphone apps are being developed to address mental health issues such as support, reminders, monitoring of mood changes and even stress levels. Tools under development from startups, academic institutions, and research clinics aim to help people manage everything from severe depression to bipolar disorder and schizophrenia. A recent article in Wired magazine points out that “through the discreet and continuous recording of social and physical behavior, these apps can detect changes in mental well-being, deliver micro-interventions when and where needed, and give patients a new awareness of their own illnesses. In the long run, they may even diminish the stigma attached to mental health disorders.”
A Boston-based company Cogito was conducting a clinical trial of an app at the time of the Boston Marathon bombing. Their smartphone application continuously and passively monitors psychological health and well-being using built-in mobile sensors and survey questions. “The bombing offers a unique pre-and post-disaster dataset for understanding the longitudinal trajectories and risk factors for PTSD following trauma. Initial analyses of the data show that survey participation dropped by ~50% during the two weeks immediately after the Boston bombing, perhaps an early indication of the PTSD symptom of withdrawal. Of those that did respond, participants reported an average of ~14% increase in severity of attitudes and behaviors linked with depression and PTSD in the two weeks following the bombing than they did in the two weeks prior.”
A number of apps are being researched to monitor the symptoms of bipolar disorder and schizophrenia. The University of Michigan is working with a company to monitor individuals with rapid-cycling bipolar disorder. Although the possibilities are interesting, many of these ‘medical apps’ are untested and unregulated. Last year the FDA released a document for guidance on medical apps, however it focused mostly on apps that diagnose or turn a smartphone into an EEG. There are no guidelines for mental health apps as yet.

A survey by Bank of America states that 47 percent of U.S. consumers admit they wouldn’t last a day without their smartphone. Additionally, of those surveyed who use their phone for mobile banking, 31 percent said they log on at least once a day, while 82 percent access their accounts at least once a week or more. These findings are part of the inaugural Bank of America Trends in Consumer Mobility Report, “a study that explores broad mobile trends and banking behaviors among adult consumers across the country who own a smartphone and have an existing banking relationship. The survey found that mobile connectivity is so critical, the smartphone falls below only the Internet and personal hygiene when ranked by importance to people’s daily lives. Ninety-one percent say their mobile phone is very important, just as important as their car (91 percent) and deodorant (91 percent); and significantly more important than television (76 percent) and coffee (60 percent). The report also found that the youngest millennials ages 18-24 are most likely to view their mobile phones as very important (96 percent) — more so than deodorant (90 percent) and even their toothbrush (93 percent).”
So who own smartphones? The Pew Research Internet Project states that “As of January 2014, 90% of American adults have a cell phone. 58% have a smartphone.”
Here is the breakdown of their study.

According to an article in this month’s JAMA, organized medicine should change the medical profession guidelines on social media use that calls on doctors to separate their personal and professional online personas. The article suggests that “instead of focusing on professional and personal boundaries, physicians should zero in on the boundary between what is appropriate and what is not. When a physician asks, ‘Should I post this on social media?’ the answer does not depend on whether the content is professional or personal but instead depends on whether it is appropriate for a physician in a public space,” the authors said.
The separation of personal and professional personae was a recommendation first made by the American Medical Association in 2010. Other physician organizations followed suit with their own guidelines, each promoting the same personal-professional separation advice. In April, the American College of Physicians and the Federation of State Medical Boards released similar guidelines. According to the JAMA authors, “Separation of identities online is operationally impossible.” They argue that an online search for a social media page would connect both personal and professional pages. “Despite the increasing availability of paid services to monitor and control a person’s Web presence, no current technology exists to overcome fully this particular barrier.”
In addition, the argument highlights that “Professional identity constitutes and is constituted by personal identity, perhaps as one of the many ‘subidentities’ or roles individuals might have, such as a spouse, parent and so on. Separation therefore verges on nonsensical. The argument is also made that separation may be harmful and that depersonalized online interactions could lead patients to believe the doctor is hiding something. They also could lead to a physician’s inability to normalize a difficult situation or express empathy.
Volunteers were recruited to provide information about their feelings and locations. The team created an application for the Android operating system that documented each person’s location and periodically sent the question, “How happy are you?”
Cell phones can efficiently capture information that is generally difficult to record and be “in the moment.” This is important because these notes are likely to be more accurate than feelings jotted down after the fact. Since our society is so mobile and ‘on-the-go,’ this study hopes to capture a range of emotions associated with a geolocation. Over a three-week period, researchers collected information from 270 volunteers in 13 countries who were asked to rate their happiness on a scale of 0 to 5. From the information collected, the researchers created and fine-tuned methods that could lead to a better understanding of how our environments influence emotional well-being. The study was published in the June issue of Demography.
According to the authors, “The mobile phone method could help overcome some of the limitations that come with surveys conducted at people’s homes. Census measurements tie people to specific areas — the census tracts in which they live — that are usually not the only areas that people actually frequent. People spend a significant amount of time outside their census tracks., If we want to get more precise findings of contextual measurements we need to use techniques like this.”
Though many of the volunteers lived in the United States, some were in Australia, Canada, China, France, Germany, Israel, Japan, Norway, South Korea, Spain, Sweden and the United Kingdom. The researchers noted that the team’s focus at this stage was not on generalizable conclusions about the link between environment and happiness, but rather on learning more about the mobile phone’s capabilities for data collection. “I’d be hesitant to try to extend our substantive findings beyond those people who volunteered.” said the lead author Palmer.

A study by the Privacy Rights Clearinghouse, a nonprofit advocacy organization in San Francisco, evaluated 43 popular free and paid apps that were made for consumer use. Apps used by health professionals were not part of the study.
Researchers reviewed the mobile application privacy policies and installed and used the apps to see what data were stored on the apps. They also looked at the communication between the apps and the Internet.
The study found that many of the apps sent unencrypted data to advertisers, probably without users’ knowledge. Seventy-two percent of the apps exposed personal information that could include dates of birth, personal location, ZIP codes, medical information, email addresses, first names, friends, interests and weights. Some apps sent information to as many as 10 third parties.
- Data were sent to app developers’ websites and third-party sites for analytic and advertising purposes.
- More than 75% of free apps and 45% of paid apps used behavioral tracking, usually through third parties, according to the study.
Paid apps, which ranged from less than $1.50 to more than $10, posed less risk to users’ privacy. That’s probably because they don’t rely only on advertisers to make money, according to the study. According to AMA News, “Physicians might think twice about advising patients to use some mobile health and fitness apps. A July report indicates that many of those apps compromise patients’ privacy. Just recommending apps may put doctors at risk for violations of the Health Insurance Portability and Accountability Act.”
A study published in Cyberpsychology, Behavior, and Social Networking evaluated 160 Facebook profiles to examine how drinking alcohol is portrayed in both text and images. A second component of the study sought to determine how friends react to these alcohol-related postings.
The analysis generated 2,575 pictures and 92 status updates referring to alcohol use, which represented about 6.50% of the pictures in the total sample and 2.90% of the text updates. These visual and textual references, as well as the peer reactions to these posts, mostly referred to alcohol use in a positive context (72.23% of the pictures and 72.83% of the messages).
The results of this study demonstrate that alcohol-related references are quite common, while negative reactions to these posts are seldom. The authors suggest that further research into the effects of these visual and textual messages is warranted.
A similar study last year in JAMA Pediatrics examined the associations between displayed alcohol use and intoxication/problem drinking (I/PD) references on Facebook and self-reported problem drinking using a clinical scale. The study included undergraduate college students (age range, 18-20 years) at 2 state universities with public Facebook profiles. The profiles were categorized into 1 of 3 categories: Nondisplayers, Alcohol Displayers, and I/PD Displayers.
Results showed that among 307 profiles identified, 224 participants completed an online survey that measured problem drinking using the Alcohol Use Disorders Identification Test (AUDIT) scale. (73% response rate). The average age was 18.8 years; 122 (54%) were female; 152 (68%) were white; and approximately 50% were from each university. Profile owners who displayed I/PD were more likely (odds ratio, 4.4; 95% CI, 2.0-9.4) to score in the problem drinking category of the AUDIT scale, had 64.0% (incidence rate ratio, 1.64; 95% CI, 1.27-11.0) higher AUDIT scores overall, and were more likely to report an alcohol-related injury in the past year (P = .002).
The authors concluded that Facebook displayed references to I/PD were positively associated with AUDIT scores suggesting problem drinking as well as alcohol-related injury. Results suggest that clinical criteria for problem drinking can be applied to Facebook alcohol references.
Welcome to Camp Grounded, an adults-only summer camp about two and half hours north of San Francisco. Approximately 300 people gathered there for three days of color wars, talent shows, flag-raisings and other regressive activities organized by Digital Detox, an Oakland-based group dedicated to helping technology-addicted people to “disconnect to reconnect.”
So many of us feel compelled to stop what we are doing and read and respond to text messages, tweets, check out a friend’s Facebook post, comment on a blog entry, etc. By removing these things that “supposedly ‘connect’ us in this wireless, oversharing, humble-bragging age, the founders of Digital Detox hoped to build real connections that run deeper than following one another on Twitter or “liking” someone’s photo on Instagram.”
Without the distractions of the Web, social media, television and breaking news, campers, ranging in age from 19 to 67, were invited to share with one another and learn about ourselves. For many, this was the first time in a decade or more that they have not had their smartphone as a 24/7 companion.
The rules of Camp Grounded were simple: no phones, computers, tablets or watches; work talk, discussion of people’s ages and use of real names were prohibited.
The goal of the Camp is “to connect people. There’s always going to be more media, more to do outside of where you are. The only moment that matters is right now.” Not having technology for a weekend and facing who you really are or are not, can offer powerful insights and reboot nature’s operating system.

Imagine having access to the technology that we see on CSI or NCIS? Or being really able to sequence DNA or have a knowledgeable virtual assistant to show you how to use all their the cool new toys that can make you a Bio-Engineer?
Labster is a bio-tech education startup founded back in 2011. It has gone further than most by creating an entire virtualized laboratory for teaching bio-tech students without the need to purchase expensive lab equipment or conduct potentially hazardous experiments for real. Labster began selling licenses for its software to universities and schools, and also to corporations for training. Current customers include Stanford, Hong Kong and Copenhagen Universities. The software has been tested by more than 10,000 students over the past year.
Students and bio-curious folk could never get access to the hundred-thousand dollar “next-generation” sequencing (NGS) machines, Electron-Microscopes or even High-Performance Liquid Chromatography (HPLC) simulation, they now have 24/7 access to a virtual 3D laboratory full of all these awesome machines, with real-life mathematical simulations of anything from basic PH base/acidity simulations to DNA manipulations and enzyme simulations (all made in Unity3D for web and iPad).
It is basically a science video game but because access to the highly expensive lab instruments and equipment its software is simulating can be dangerous, the access to some aspects is necessarily limited. It’s offering free user accounts for people signing up in the first three months. After which it will be charging for use — with a fee for each new virtual cases (going the downloadable content route), selling via the iPad App Store.
As society struggles with wearable technology and privacy, along comes the “computer in a pill” that can monitor our internal systems. Inside the pills are sensors and transmitters. After ingestion, they make their way through the stomach and intestines and relay information.
One company, Proteus Digital Health, makes one of these swallowable health monitors which needs no battery, the body is the power source much like the science project of a potato what can power a light bulb – the Proteus pill has added magnesium and copper on each side of its sensor, which can generate electricity from stomach acids.
