不顯示數(shù)字的體重秤有助于減肥？

The scale of the future does not have numbers or dials. It won't even tell you how much you weigh. It doesn't have a screen to display your weight because, if you ask behavioral economist at Duke University Dan Ariely, weight is a metric of the past.

未來(lái)的體重秤沒有數(shù)字和表盤，不會(huì)告訴你有多重，甚至它連顯示體重的屏幕都沒有。如果你想知道原因的話，杜克大學(xué)的行為經(jīng)濟(jì)學(xué)家Dan Ariely會(huì)告訴你，體重只是一個(gè)關(guān)于過(guò)去的測(cè)量數(shù)值。

Ariely has spent his career researching the invisible machinery of human choice: why we neglect to save money for things we need we know, why we lie to our friends, and to ourselves.

Airely一直致力于探求人們決策過(guò)程的不可見機(jī)制：為什么我們會(huì)忘記為那些必需品存錢，為什么我們會(huì)欺騙朋友、欺騙自己。

Recently, he's turned his focus toward the choices we make about our health. Why, Ariely wondered, do people have such a hard time making healthy choices?

最近，他開始研究與健康相關(guān)的抉擇。Ariely想知道，為什么做出健康的選擇這么難呢?

Ariely imagines the common bathroom gadget as a gateway to better understanding our health, a way to subtly reshape human health behavior one pound at a time. But in order to do that, Ariely wants to rethink the scale's design.

Ariely認(rèn)為，通過(guò)浴室里一個(gè)常見的小物件，可以更好地了解人們的健康狀況。這是一種塑造健康行為的巧妙方法。為了達(dá)到這一需求，Ariely想要重新設(shè)計(jì)一款體重秤。

 

 

Most scales remind people of the shame, regret, and self-disgust they feel when they step onto one.

當(dāng)普通體重秤上的數(shù)值又上升一格時(shí)，人們會(huì)感到羞愧、后悔和自我厭棄。

Even the simplest nugget of data can be misleading. When you see your weight go up two pounds, you assume you've done something wrong. When you see your weight go down two pounds, you assume you've done something right. Most of the time, you haven't done anything at all.

最簡(jiǎn)單的數(shù)據(jù)也可能會(huì)誤導(dǎo)你。當(dāng)你看到體重增加了兩磅，你會(huì)覺得你做錯(cuò)了什么。當(dāng)你看到體重下降兩磅時(shí)，你會(huì)以為已經(jīng)做了一些正確的事。其實(shí)大多數(shù)時(shí)候，你什么都沒做。

"It's incredibly confusing and demotivating," says Ariely. "So we said, 'OK, let's rethink the numberless scale.'" More encouragement, less data. Ariely's dream of the unquantified self.

Ariely說(shuō)：“這簡(jiǎn)直是撲朔迷離，讓人失去了減肥的動(dòng)力。所以我覺得，我們要再考慮一下不顯示數(shù)字的體重秤。”更多的鼓勵(lì)，更少的數(shù)據(jù)。Ariely想要一個(gè)不被量化的體重秤。

The smart scale designed by Ariely captures bone density and muscle mass in addition to overall weight, and it connects to your phone. You simply step on, and step off. And it never tells you how much you weigh, not even in the app.

除了測(cè)體重，Ariely設(shè)計(jì)的智能秤還可以獲取骨密度和肌肉量，同時(shí)關(guān)聯(lián)著你的手機(jī)。你只需要站上去，然后下來(lái)。秤上不會(huì)顯示你的體重值，APP上也不會(huì)。

Instead, it analyzes all the granular information about your body and translates it into simple humanspeak: either you're doing fine, or you're not.

但是，它會(huì)綜合分析身體相關(guān)的所有信息，并將其轉(zhuǎn)換為最簡(jiǎn)單的人類語(yǔ)言：你做地很好，或者你表現(xiàn)不好。

Everything else happens in the scale's app, which connects to the scale via Bluetooth. The app also pulls data from the health kit on your phone — so, if you wear a smart watch, or track your workouts through a mobile app like Keep, it can synthesize that data along with your weight.

APP與體重計(jì)通過(guò)藍(lán)牙連接。APP可以從手機(jī)上安裝的健康工具中提出數(shù)據(jù) —— 因此，如果你佩戴智能手環(huán)，或使用像Keep這樣的APP跟蹤記錄運(yùn)動(dòng)，它可以將這些數(shù)據(jù)與體重?cái)?shù)據(jù)綜合起來(lái)。

Then, it then presents your health on a five-point scale: Either you're a little better, a little worse, much better, much worse, or basically the same.

然后，它會(huì)以五個(gè)等級(jí)呈現(xiàn)你目前的健康狀況：好點(diǎn)了、有點(diǎn)不太好、好很多了、變差了很多、或沒什么變化。

The five-point system takes into account the way people actually gain and lose weight. A few pounds up or down means nothing at all, especially if it's not sustained over time.

五檔分類考慮到了人們實(shí)際增重和減肥的過(guò)程。體重上升或下降幾磅沒有任何意義，特別是如果這種變化并沒有持續(xù)一段時(shí)間。

So the app creates a running average of weigh-ins over the past three weeks, and uses that to give feedback rather than your weight in a given moment. "If you're within one standard deviation," Ariely says, "then we say, 'You're just the same.'"

因此，這個(gè)APP計(jì)算的是三周內(nèi)的平均重量，然后反饋信息，而不是直接顯示體重值。“如果體重變化是在標(biāo)準(zhǔn)偏差范圍內(nèi)，APP會(huì)顯示，‘沒什么變化。’”Ariely說(shuō)。

He thinks this approach will help people better understand how their choices are affecting their health overall, rather than what makes someone gain or lose a few fractions of a pound in a day.

他認(rèn)為這種方法可以幫助人們更好地理解自己的選擇如何影響健康狀況，而不是讓某個(gè)人在一天內(nèi)增加或者減少一點(diǎn)點(diǎn)體重。

A five-month study to test the screenless scale has shown that in a control condition, people who used a regular scale gained 0.3 percent weight every month; People in the other group, using the numberless scale, lost 0.6 percent weight per month.

以測(cè)試這種不顯示數(shù)字的體重計(jì)的效果為研究目的的一項(xiàng)研究進(jìn)行了五個(gè)月。研究結(jié)果顯示：使用普通體重計(jì)的對(duì)照組平均每個(gè)月增重0.3%;使用無(wú)數(shù)字體重秤的實(shí)驗(yàn)組，平均每個(gè)月減重0.6%。

"That means we can take an everyday object, like a scale. Look at it from perspective of social science, think about it in a different way, and design it in a way that will be more compatible with how we make decisions to get the best results. It is not just the scale," Ariely says in a speech.

Ariely在演講中說(shuō)，“這意味著我們可以將日常生活中的一個(gè)物件，比如體重計(jì)，通過(guò)社會(huì)科學(xué)的方法，從不同的方式去思考，然后將其設(shè)計(jì)得與我們的日常決策更相容，以幫助我們?nèi)〉酶玫慕Y(jié)果。除了設(shè)計(jì)體重秤，這些知識(shí)還可以用在其他事情上。”
