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.
Map of the Day: Navigating the IRS
The Taxpayer Advocate Service – an independent organization within the IRS whose roughly 1,800 employees both assist taxpayers in resolving problems with the tax collection agency and recommend changes aimed at improving the system – released a “subway map” that shows the “the stages of a taxpayer’s journey.” The colorful diagram includes the steps a typical taxpayer takes to prepare and file their tax forms, as well as the many “stations” a tax return can pass through, including processing, audits, appeals and litigation. Not surprisingly, the map is quite complicated. Click here to review a larger version on the taxpayer advocate’s site.
A Surprise Government Spending Slowdown
Economists expected federal spending to boost growth in 2019, but some of the fiscal stimulus provided by the 2018 budget deal has failed to show up this year, according to Kate Davidson of The Wall Street Journal.
Defense spending has come in as expected, but nondefense spending has lagged, and it’s unlikely to catch up to projections even if it accelerates in the coming months. Lower spending on disaster relief, the government shutdown earlier this year, and federal agencies spending less than they have been given by Congress all appear to be playing a role in the spending slowdown, Davidson said.
Number of the Day: $203,500
The Wall Street Journal’s Catherine Lucey reports that acting White House Chief of Staff Mick Mulvaney is making a bit more than his predecessors: “The latest annual report to Congress on White House personnel shows that President Trump’s third chief of staff is getting an annual salary of $203,500, compared with Reince Priebus and John Kelly, each of whom earned $179,700.” The difference is the result of Mulvaney still technically occupying the role of director of the White House Office of Management and Budget, where his salary level is set by law.
The White House told the Journal that if Mulvaney is made permanent chief of staff his salary would be adjusted to the current salary for an assistant to the president, $183,000.
The Census Affects Nearly $1 Trillion in Spending
The 2020 census faces possible delay as the Supreme Court sorts out the legality of a controversial citizenship question added by the Trump administration. Tracy Gordon of the Tax Policy Center notes that in addition to the basic issue of political representation, the decennial population count affects roughly $900 billion in federal spending, ranging from Medicaid assistance funds to Section 8 housing vouchers. Here’s a look at the top 10 programs affected by the census:
Chart of the Day: Offshore Profits Continue to Rise
Brad Setser, a former U.S. Treasury economist now with the Council on Foreign Relations, added another detail to his assessment of the foreign provisions of the Tax Cuts and Jobs Act: “A bit more evidence that Trump's tax reform didn't change incentives to offshore profits: the enormous profits that U.S. firms report in low tax jurisdictions continues to rise,” Setser wrote. “In fact, there was a bit of a jump up over the course of 2018.”
