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.
Chart of the Day: Why US Fertility Rates Are Falling
U.S. fertility rates have fallen to record lows for two straight years. “Because the fertility rate subtly shapes many major issues of the day — including immigration, education, housing, the labor supply, the social safety net and support for working families — there’s a lot of concern about why today’s young adults aren’t having as many children,” Claire Cain Miller explains at The New York Times’ Upshot. “So we asked them.”
Here are some results of the Times’ survey, conducted with Morning Consult. Read the full Times story for more details.
A Record Low 47% of US Adults Say They're 'Extremely Proud' to Be American
Gallup says that, for the first time in the 18 years it’s been asking U.S. adults how proud they are to be Americans, fewer than half say they are "extremely proud." Just 47 percent now say they’re extremely proud, down from 70 percent in 2003.
Another 25 percent say they’re “very proud” — but the combined 72 percent who say they’re extremely or very proud is also the lowest Gallup has recorded. Pride levels among liberals and Democrats have plunged since 2017. Overall, 74 percent of Republicans and just 32 percent of Democrats call themselves “extremely proud” to be American.
Pfizer Has Raised Prices on 100 of Its Products
Weeks after President Trump said that drugmakers were about to implement “voluntary massive drops in prices” — reductions that have yet to materialize — Pfizer has raised prices on 100 of its products, The Financial Times’s David Crow reports:
“The increases were effective as of July 1 and in most cases were more than 9 per cent — well above the rate of inflation in the US, which is running at about 2 per cent. … Pfizer, the largest standalone drugmaker in the US, did decrease the prices of five products by between 16 per cent and 44 per cent, according to the figures.”
Crow notes that Pfizer also raised prices on many of its medicines in January, meaning that some prices have been hiked by nearly 20 percent this year. The drugmaker said that it was only changing prices on 10 percent of its medicines and that list prices did not reflect what most patients or insurers actually paid. The net price increase after rebates and discounts was expected to be in the “low single digits,” the company told the FT.
Chart of the Day: Pass-Through Tax Deductions Made Easy
The Republican tax overhaul was supposed to simplify the tax code, but most experts say it fell well short of the goal. Martin Sullivan, chief economist at Tax Analysts, tweeted out a chart of the analysis required to determine whether income qualifies for the passthrough tax deduction of 20 percent, and as you’ll see, it’s anything but simple.
A Conservative Bashes GOP Dysfunction on Spending Cuts
Brian Riedl, a senior fellow at the conservative Manhattan Institute, offers a blistering critique of congressional Republican’s problems cutting spending:
Since the Republicans took the House in 2011, nearly every annual budget blueprint has promised to balance the budget within a decade with anywhere from $5 trillion to $8 trillion in spending cuts. And yet, you may have noticed, the budget has not moved towards balance. This is because the budget merely sets a broad fiscal goal. To actually cut spending, Congress must follow up with specific legislation to reform Medicare, Medicaid, and all the other targeted programs. In reality, most lawmakers who pass these budgets have no intention whatsoever of cutting this spending. As soon as the budget is passed, the targets are forgotten. The spending-cut legislation is never even drafted, much less voted on.
The annual budget exercise is thus a cynical exercise in symbolism. Congress calculates how much spending must be cut over ten years to balance the budget. Then they pass legislation setting a goal of cutting that amount. Then they move on to other business. It’s like a baseball team announcing that they voted to win the next World Series, and then not showing up to play the season.
