Do Fitbits make you sad?

Duke University business professor Jordan Etkin found evidence they might:

"In general, tracking activity can increase how much people do," Etkin said. "But at the same time, measurement has these pernicious effects. Enjoyable activities can became almost like a job, by focusing on the outcomes of things that used to be fun."

In another study, researchers had 310 participants read for eight minutes. One group read additional text that described reading as fun an enjoyable; for another group it was described as useful and educational — more like work. A third group received no additional information. In all three groups, some readers were told how many pages they had read as they went, others were not.

The readers who could see how many pages they had read reported that reading felt more like work and less enjoyable than those who could not — but not among participants who were told the project was more work-like at the start.

"This doesn't mean we should stop measuring our daily activity," she said, "but we need to balance that increased productivity against our underlying enjoyment. For activities people do for fun, it may be better not to know."

Finding out that my Fitbit might make me sad makes me sad.

Of course, this could just be a horrible example of bad science reporting, which Deeply Trivial just blogged about yesterday.

Missing my Fitbit numbers

For the last couple of days, I've missed my 10,000-step goal by 100 to 500 steps. This is why:

Yesterday Chicago got its biggest November snowfall in 120 years; today it's well below freezing. Walking is treacherous at best for bipeds and uncomfortable for quadrupeds. So today might also be a miss.

I haven't missed three days in a row since March 5th-7th—when, not coincidentally, we had a miserable, snowy week. Winter is hard on fitness.

A year of FitBit

I forgot that I picked up my FitBit a year ago this week. So how am I doing since 24 October 2014?

  • 4.76 million steps (13,000 per day)
  • 4,081 km (11 km per day)
  • 4,557 floors (12 per day)

By FitBit's reckoning, that puts me somewhere around the 90th percentile of FitBit users worldwide. It also means I've walked the entire length of Japan and climbed enough stairs to reach the normal cruising altitude of a commercial jet.

And Parker and I are about to get more steps in just a few minutes.

FitBit attack vector?

Via Schneier, a report that FitBit trackers could, in theory, spread malware to users' computers:

The athletic-achievement-accumulating wearables are wide open on their Bluetooth ports, according to research by Fortinet. The attack is quick, and can spread to other computers to which an infected FitBit connects.

Attacks over Bluetooth require an attacker hacker to be within metres of a target device. This malware can be delivered 10 seconds after devices connect, making even fleeting proximity a problem. Testing the success of the hack takes about a minute, although it is unnecessary for the compromise.

"Fortinet first contacted us in March to report a low-severity issue unrelated to malicious software. Since that time we’ve maintained an open channel of communication with Fortinet. We have not seen any data to indicate that it is currently possible to use a tracker to distribute malware," [FitBit said].

The researcher has made it clear that this is a proof-of-concept attack, and not one that exists in the wild.

FitBit challenge: crushed

The final score from my FitBit challenge over the weekend was: friend, 33,800; me, 37,800. Yesterday I gave Parker 3 hours of walks and also walked home from dinner instead of taking public transit or a Divvy, which got me almost to 23,800 steps (and 17.7 km) for the day.

There was a cost. My feet hurt, Parker was lethargic this morning, and I ate too much. And this week it's not likely I'll get 10,000 steps in every day this week because I've got an all-day meeting Wednesday. Which is probably a good thing, according to my feet and my dog.

FitBit challenge

Following a friend's example, I got a FitBit this week. The same friend has challenged me for the weekend, getting 15,300 steps to my 14,000 yesterday, and going hiking this afternoon. Ah, but I have a dog, you see. And the weather is perfect. So far today I've walked 15,400 steps (11.6 km), almost all of it with Parker, and we're about to go out for another walk.

Here's walk #1, this morning, in Lincoln Park:

And walk #2, at lunchtime, down the Lakefront Path:

I got my 15,000-step badge on Friday, my first full day with the thing. Today I'm aiming for 20,000. My friend is too. This will be close, I'm guessing...
