Now, the next thing that you need to understand is how to design with data.
另外一件你需要明白的事情就是如何在設計過程中應用數據。
Now, when you're working on products like this,you have incredible amounts of information about how people are using your product that you can then use to influence your design decisions,but it's not just as simple as following the numbers.
當你在設計一件這樣的產品的時候，你有大量關于人們會怎樣使用你的產品的信息,這將會影響你的設計理念，但是這不僅僅只關系到一堆數字。
Let me give you an example so that you can understand what I mean.
讓我來舉一個例子,你就會明白我在說什么了。
Facebook has had a tool for a long time that allowed people to report photos that may be in violation of our community standards,things like spam and abuse.
臉書在很久之前就有一個工具是用來讓人們反饋那些照片可能會給人們帶來不便的照片，例如就好像垃圾郵件和濫用信息。
And there were a ton of photos reported,but as it turns out,only a small percentage were actually in violation of those community standards.
每天有成千上萬的照片被上傳，但是事實證明，只有很小的一部分違反社區標準。
Most of them were just your typical party photo.
大多數是派對的照片。
Now, to give you a specific hypothetical example,let's say my friend Laura hypothetically uploads a picture of me from a drunken night of karaoke.
我們來假設一個具體的例子，比如假設我有個好朋友叫勞拉,她上傳了一張我醉酒后在卡拉ok的照片。
This is purely hypothetical, I can assure you.
我向你保證，這真的只是一個假設。
Now, incidentally,you know how some people are kind of worried that their boss or employee is going to discover embarrassing photos of them on Facebook?
順便說一句，你也知道現在有一些人擔心他們的老板或是員工看到他們在臉書上的不雅照片？
Do you know how hard that is to avoid when you actually work at Facebook?
你知道不讓我的朋友看見這些照片有多么困難么,尤其是我還在facebook上班！
So anyway, there are lots of these photos being erroneously reported as spam and abuse,and one of the engineers on the team had a hunch.
所以，當大量這類照片被當成是垃圾信息或是信息濫用來處理的時候，團隊的一個工程師有了預感。
He really thought there was something else going on and he was right,because when he looked through a bunch of the cases,he found that most of them were from people who were requesting the takedown of a photo of themselves.
他覺得這當中一定有什么,而且 他是對的，因為當他看到這么多案例以后，他發現大多數的反饋信息是來自那些照片的當事人,他們要求刪除有他們自己的照片。
Now this was a scenario that the team never even took into account before.
在這之前，我們的團隊從未考慮到這個情況問題。
So they added a new feature that allowed people to message their friend to ask them to take the photo down.
所以他們新加了一個功能就是允許人們發信息給他們的朋友讓他們把照片刪除。
But it didn't work.
但是，這并不起作用。
Only 20 percent of people sent the message to their friend.
只有百分之二十的人給他們的朋友發了消息。
So the team went back at it.
所以我們的工作人員又回到了這個問題上。
They consulted with experts in conflict resolution.
他們咨詢了專家該如何解決沖突。
They even studied the universal principles of polite language,which I didn't even actually know existed until this research happened.
他們甚至學習了禮貌用語的通用原則，直到他們做了這項研究以前我都不知道還有這樣原則存在，
And they found something really interesting.
我們的工作人員發現了 一件很有趣的事情，
They had to go beyond just helping people ask their friend to take the photo down.
他們不僅僅幫助人們讓他們朋友把照片從網上刪除。
They had to help people express to their friend how the photo made them feel.
同時也讓他們的朋友了解到被上傳照片的人的心情。
Here's how the experience works today.
如今的設計就是這個經歷所帶來的。
So I find this hypothetical photo of myself,and it's not spam, it's not abuse,but I really wish it weren't on the site.
當我看到自己這張假設的照片的時候，它既不是垃圾郵件也不是濫用郵件，但是我真的不希望在網上看到這張照片。
So I report it and I say,I'm in this photo and I don't like it,and then we dig deeper.
所以我反饋了意見，并寫道，我在這張照片里，但是我不喜歡這張照片，然后我們進一步去探討。
Why don't you like this photo of yourself?
為什么你不喜歡這張有你自己的照片?
And I select It's embarrassing.
我選擇了：它讓我感到難堪。
And then I'm encouraged to message my friend,but here's the critical difference.
然后我被鼓勵去發消息給我的朋友，然而這就是不同的關鍵。
I'm provided specific suggested language that helps me communicate to Laura how the photo makes me feel.
臉書上會給我提供專門的建議用語用來幫助我和勞拉交流我對這個照片的想法。
Now the team found that this relatively small change had a huge impact.
我們的工作人員發現，這個小小的改變帶來了巨大的影響。
Before, only 20 percent of people were sending the message,and now 60 percent were,and surveys showed that people on both sides of the conversation felt better as a result.
在這之前，只有20%的人會發信息給他們的朋友，但是現在有60%的人會去發消息，據調查顯示對話的雙方最后都會覺得不錯。
That same survey showed that 90 percent of your friends want to know if they've done something to upset you.
據同一調查顯示，你90%的朋友希望知道自己是否做了什么讓你不高興的事情。
Now I don't know who the other 10 percent are,but maybe that's where our Unfriend feature can come in handy.
我不知道另外10%的人的想法，但是也許就是到了我們解除好友的按鍵非常好用的時候了。
So as you can see,these decisions are highly nuanced.
正如你所看到的，這些改變是很微妙的。
Of course we use a lot of data to inform our decisions,but we also rely very heavily on iteration,research, testing, intuition, human empathy.
當然，這個過程中我們用了很多數據來支持我們的決定，同時我們以反復試驗，研究，測試，直覺以及人類的同理心為主。
It's both art and science.
這是藝術和科學的融合。
Now, sometimes the designers who work on these products are called data-driven,which is a term that totally drives us bonkers.
現在有時候，我們也把這些設計者叫做數據驅動者，這完全一個讓我們瘋狂的詞。
The fact is, it would be irresponsible of us not to rigorously test our designs when so many people are counting on us to get it right,but data analytics will never be a substitute for design intuition.
事實上，我們會因為沒有嚴格測試我們的設計產品而被認為是不負責任的，尤其是當有那么多的人在指望著我們做對事情的時候，但是數據分析絕對不會代替設計的直覺。
Data can help you make a good design great,but it will never made a bad design good.
數據能幫助我們使設計變得更加完美，但是絕對不會把一個不好的設計變成好的。
