# 做一個有知覺的產品 第十四課里，Keith Rabois 提到應該“關注那些不正常的數據”時舉了兩個例子，一個是 Paypal 的，一個是 Linkedin 的。而第二個例子很好玩，更適合講另外一個道理，**一定要做有知覺的產品**： > One insight I have had over my career is what you, you kind of want to look for the anomalies... > > ... I was at LinkedIn and I saw this stat that made no sense to me. The UI of the site was a little different then. 25% of all clicks, maybe 35% of all clicks from the homepage were people going to their own profile. And that didn't make any sense whatsoever. It was in the settings, you had to go to the margin and find a link. It was 25-35% of every click at scale, so this is just invalid stuff. And it made no sense whatsoever. I had never seen UI perform that way. > > I went around for weeks trying to figure this out, then someone smart, actually it was Max Levchin, said something to me and I was like, he was like, it's vanity. I was like, ah ha! People are looking at themselves in the mirror. Thats a very good answer, because they weren't editing their profile. Nobody has something to edit everyday in their profile. But they were just looking at themselves in the mirror every day because it made them feel good. Then you could test that with, if I had more content would I look at myself in the mirror more often? It turns out, you did. If you had more endorsements would you look at yourself more in the mirror? You did. So we figured out what was underneath the utilitarian product, the product the team thought they were building was actually more emotional vanity. 我喜歡有知覺的產品——這是做?[knewone](http://knewone.com/)?時學會并養成的習慣。現在開發者可以利用各式各樣的工具監控自己的產品每一處被點擊、被查看的數據。 當我有機會與某個團隊談他們的產品時，我最喜歡看的就是他們分析數據的方式（要是連數據都不給看，那就不用談了）——這是我做 DD 的最根本依據。 連我一個外行都很奇怪，怎么在今天還會有那么多團隊在維護一個完全沒有知覺的產品，他們連瞎子都不如，那產品完全是木頭疙瘩。少數團隊確實給自己的產品加上了一些監控指標，但粗糙得像單細胞動物。只有極少數極少數團隊花很長時間，用很耐心的方式一點一點給自己的產品加上各種各樣的知覺，然后再用很高級卻又很簡單的方式分析、處理、回應這些知覺，這樣的產品才是有生命的。即便如此，還是不夠，因為有了生命之后還要有[靈魂](http://zhibimo.com/read/xiaolai/growth/make-a-product-that-has-a-soul.html)，否則無法稱雄稱霸。 怎樣才能為一個產品注入靈魂？Keith Rabois 其實在這節課里有回答的。他引用了 Bill Walsh 的一本書，[The Score Takes Care of Itself](http://www.amazon.com/The-Score-Takes-Care-Itself/dp/1591843472)?里的一段文字： > “Do you know how to tell if you’re doing the job? If you’re up at 3 AM every night talking into a tape recorder and writing notes on scraps of paper, have a knot in your stomach and a rash on your skin, are losing sleep and losing touch with your wife and kids, have no appetite or sense of humor, and feel that everything might turn out wrong, then you’re probably doing the job.” 一個產品經理，在為自己的產品加上各種各樣的知覺之后，把那些知覺當作自己的神經末梢，用自己全部的時間精力去處理那些知覺，有靈魂的產品經理做出的產品就這樣有了靈魂。這不是鬼話，是我見過的頂級產品經理最自然不過的行為習慣。
