What Your Smartphone Knows That Your Mother Doesn’t
Can Your Smartphone Be Used to Detect Depression?
It’s always there, in your pocket or purse or on your desk, quietly collecting information. And apparently, when it comes to depression, there’s quite a lot your smartphone knows about you.
According to a small study from Northwestern Medicine, that data from your smartphone can predict with eerie 87 percent accuracy whether you’re suffering from depression or not.
The telling signs: You spend more time on your smartphone and less time leaving the house, and you visit very few places each day.

The researchers used Craigslist to find 40 test subjects between the ages of 19 and 58, and outfitted their smartphones with an app to monitor their location and usage. The individuals took a questionnaire that measured signs of depression; half of the subjects had troubling symptoms and half did not. Using GPS, the phones tracked the subjects’ movements and locations every five minutes. The subjects also were asked questions about their mood at different points during the day.
These factors were then correlated with the test subjects’ original depression test scores. And the results were uncanny. Depressed people used their phones more often and for longer periods of time —an average of 68 minutes a day. By comparison, the individuals who didn’t show signs of depression spent only 17 minutes on theirs. Researchers attributed the increased use of the phone to task avoidance, another symptom of depressed people.
Perhaps more significant than the findings of this small study — only 28 of the 40 subjects had enough data to be studied — is the potential the researchers felt that smartphones could play in future medical diagnosis.
When loaded up with the correct sensors, the smartphone can be used to detect a person’s emotional states, and monitor moods, without the user having to utter a word. It also has the ability to offer suggestions to reinforce positive behaviors when depression is detected. The results of the study were published in the Journal of Medical Internet Research yesterday, but one conclusion was becoming increasingly evident even before the report came out: Smartphones — and the sensors they now contain — just keep getting smarter.
Stat of the Day: 0.2%
The New York Times’ Jim Tankersley tweets: “In order to raise enough revenue to start paying down the debt, Trump would need tariffs to be ~4% of GDP. They're currently 0.2%.”

Number of the Day: 44%
The “short-term” health plans the Trump administration is promoting as low-cost alternatives to Obamacare aren’t bound by the Affordable Care Act’s requirement to spend a substantial majority of their premium revenues on medical care. UnitedHealth is the largest seller of short-term plans, according to Axios, which provided this interesting detail on just how profitable this type of insurance can be: “United’s short-term plans paid out 44% of their premium revenues last year for medical care. ACA plans have to pay out at least 80%.”
Number of the Day: 4,229
The Washington Post’s Fact Checkers on Wednesday updated their database of false and misleading claims made by President Trump: “As of day 558, he’s made 4,229 Trumpian claims — an increase of 978 in just two months.”
The tally, which works out to an average of almost 7.6 false or misleading claims a day, includes 432 problematics statements on trade and 336 claims on taxes. “Eighty-eight times, he has made the false assertion that he passed the biggest tax cut in U.S. history,” the Post says.
Number of the Day: $3 Billion
A new analysis by the Department of Health and Human Services finds that Medicare’s prescription drug program could have saved almost $3 billion in 2016 if pharmacies dispensed generic drugs instead of their brand-name counterparts, Axios reports. “But the savings total is inflated a bit, which HHS admits, because it doesn’t include rebates that brand-name drug makers give to [pharmacy benefit managers] and health plans — and PBMs are known to play games with generic drugs to juice their profits.”
Chart of the Day: Public Spending on Job Programs
President Trump announced on Thursday the creation of a National Council for the American Worker, charged with developing “a national strategy for training and retraining workers for high-demand industries,” his daughter Ivanka wrote in The Wall Street Journal. A report from the president’s National Council on Economic Advisers earlier this week made it clear that the U.S. currently spends less public money on job programs than many other developed countries.
