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.
Small Business Owners Say They’re Raising Worker Pay
A record percentage of small business owners say they are raising pay for their workers, according to the latest monthly jobs report from the National Federation of Independent Business, based on a survey of 10,000 of the group’s members. A seasonally adjusted net 35 percent of small businesses say they are increasing compensation. “They are increasing compensation at record levels and are continuing to hire,” NFIB President and CEO Juanita Duggan said in a statement accompanying the report. “Post tax reform, concerns about taxes and regulations are taking a backseat to their worries over filling open positions and finding qualified candidates.”
The US Is Running Short on More Than 200 Drugs
The U.S. is officially running short on 202 drugs, including some medical staples like epinephrine, morphine and saline solution. “The medications most vulnerable to running short have a few things in common: They are generic, high-volume, and low-margin for their makers—not the cutting-edge specialty drugs that pad pharmaceutical companies’ bottom lines,” Fortune’s Erika Fry reports. “Companies have little incentive to make the workhorse drugs we use most.” And much of the problem — “The situation is an emergency waiting to be a disaster,” one pharmacist says — can be tied to one company: Pfizer.

Chart of the Day: Could You Handle a Sudden $400 Expense?
More Americans say they are living comfortably or at least “doing okay” financially, according to the Federal Reserve’s Report on the Economic Well-Being of U.S. Households in 2017. At the same time, four in 10 adults say that, if faced with an unexpected expense of $400, they would not be able to cover it or would cover it by selling something or borrowing money. That represents an improvement from 2013, when half of all adults said they would have trouble handling such an expense, but suggests that many Americans are still close to the edge when it comes to their personal finances.
Kevin Brady Introduces Welfare Reform Bill
The Tax Policy Center’s Daily Deduction reports that Rep. Kevin Brady (R-TX), chair of the House Ways and Means Committee on Friday introduced The Jobs and Opportunity with Benefits and Services (JOBS) for Success Act (H.R. 5861). “The bill would rename the Temporary Assistance for Needy Families (TANF) program and target benefits to the lowest-income households. Although the House GOP leadership promised to include an expansion of the Earned Income Tax Credit as part of an upcoming welfare reform bill, this measure does not appear to include any EITC provisions.” The committee will mark up the bill on Wednesday.
