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.
It’s Official: No Government Shutdown – for Now
President Trump signed a short-term continuing resolution today to fund the federal government through Friday, December 22.
Bloomberg called the maneuver “a monumental piece of can kicking,” which is no doubt the case, but at least you’ll be able to visit your favorite national park over the weekend.

Greenspan Has a Warning About the GOP Tax Plan
The Republican tax cuts won’t do much for economic growth, former Federal Reserve Chair Alan Greenspan told CNBC Wednesday, but they will damage the country’s fiscal situation while creating the threat of stagflation. "This is a terrible fiscal situation we've got ourselves into," Greenspan said. "The administration is doing tax cuts and a spending decrease, but he's doing them in the wrong order. What we need right now is to focus totally on reducing the debt."
The US Economy Hits a Sweet Spot
“The U.S. economy is running at its full potential for the first time in a decade, a new milestone for an expansion now in its ninth year,” The Wall Street Journal reports. But the milestone was reached, in part, because the Congressional Budget Office has, over the last 10 years, downgraded its estimate of the economy’s potential output. “Some economists think more slack remains in the job market than October’s 4.1% unemployment rate would suggest. Also, economic output is still well below its potential level based on estimates produced a decade ago by the CBO.”
The New York Times Drums Up Opposition to the Tax Bill
The New York Times editorial board took to Twitter Wednesday “to urge the Senate to reject a tax bill that hurts the middle class & the nation's fiscal health.”
Using the hashtag #thetaxbillshurts, the NYT Opinion account posted phone numbers for Sens. Susan Collins, Bob Corker, Jeff Flake, James Lankford, John McCain, Lisa Murkowski and Jerry Moran. It urged readers to call the senators and encourage them to oppose the bill.
In an editorial published Tuesday night, the Times wrote that “Republican senators have a choice. They can follow the will of their donors and vote to take money from the middle class and give it to the wealthiest people in the world. Or they can vote no, to protect the public and the financial health of the government.”

Can Trump Succeed Where Mnuchin and Cohn Have Flopped?
President Trump met with members of the Senate Finance Committee Monday and is scheduled to attend Senate Republicans’ weekly policy lunch and make a personal push for the tax plan on Tuesday. Will he be a more effective salesman than surrogates in his administration?
Politico’s Annie Karni and Eliana Johnson report that both Democrats and Republicans say Mnuchin and chief economic adviser Gary Cohn have repeatedly botched their tax pitches, “in part due to their own backgrounds” as wealthy Goldman Sachs alums. “House Speaker Paul Ryan earlier this month asked the White House not to send Mnuchin to the Hill to talk with Republican lawmakers about the bill, according to two people familiar with the discussions — though Ryan has praised the Treasury secretary’s ability to improve the legislation itself,” Karni and Johnson write.
