Schwartz Department of Microbiology, UVA Health System, University of Virginia, Charlottesville, VA 22908, USA e-mail: maschwartz@virginia.edu Accepted 9 April 2008 I recently saw an old friend for the first time in many years. We had been Ph.D. students at the same time, both studying science, although in different areas. She later dropped out of graduate school, went to Harvard Law School and is now a senior lawyer for a major environmental organization. At some point, the conversation turned to why she had left graduate school. To my utter astonishment, she said it was because it made her feel stupid. After a couple of years of feeling stupid every day, she was ready to do something else. 最近我遇到一位許久未碰面的老朋友，我們在同一時間念研究所，一起研究科學，儘管是在不同領域。她研究所念到一半放棄，轉攻哈佛法學院，現在在一家大型環境公司擔任資深律師。聊天話題轉到她當時為什麼會放棄研究所。讓我吃驚的是，她說那是因為唸研究所讓她覺得自己很笨。有好些年她每天都覺得自己很笨，所以她決定要去做些其他事。 I had thought of her as one of the brightest people I knew and her subsequent career supports that view. What she said bothered me. I kept thinking about it; sometime the next day, it hit me. Science makes me feel stupid too. It's just that I've gotten used to it. So used to it, in fact, that I actively seek out new opportunities to feel stupid. I wouldn't know what to do without that feeling. I even think it's supposed to be this way. Let me explain. 我一直認為她在我所認識的人之中是最聰明的，於她隨後的職場表現也證明了我的觀點。她所說的話困擾著我，我一直想著這件事。有一天，我心頭一震，是的，科學這碼事也讓我覺得自己很笨，只不過我已經習慣這種感覺了。事實上我想到了該如何運用這種感覺，我不知道若沒這種感覺我該做甚麼。我甚至覺得這不是本來就理所當然的嗎？請聽我解釋。 For almost all of us, one of the reasons that we liked science in high school and college is that we were good at it. That can't be the only reason – fascination with understanding the physical world and an emotional need to discover new things has to enter into it too. But high-school and college science means taking courses, and doing well in courses means getting the right answers on tests. If you know those answers, you do well and get to feel smart. 對大多數的人來說，之所以在高中、大學會喜歡科學是因為成績表現突出。這不見得是唯一的原因，對了解世界運行深感興趣以及很想發現新事物也是可能的理由。但是高中、大學的科學代表著修課，而在課堂上表現良好意謂著在考試回答正確答案。如果你知道這些答案，你會表現傑出而覺得自己聰明。 A Ph.D., in which you have to do a research project, is a whole different thing. For me, it was a daunting task. How could I possibly frame the questions that would lead to significant discoveries; design and interpret an experiment so that the conclusions were absolutely convincing; foresee difficulties and see ways around them, or, failing that, solve them when they occurred? My Ph.D. project was somewhat interdisciplinary and, for a while, whenever I ran into a problem, I pestered the faculty in my department who were experts in the various disciplines that I needed. I remember the day when Henry Taube (who won the Nobel Prize two years later) told me he didn't know how to solve the problem I was having in his area. I was a third-year graduate student and I figured that Taube knew about 1000 times more than I did (conservative estimate). If he didn't have the answer, nobody did. 在博士班你必須開始研究計畫，這是完全不同的事。對我而言，這是令人氣餒的任務。我怎麼可能構想能引領重要發現的題目？設計並執行實驗而能給予令人信服的結論？預見困難並找尋方法繞過困難，或是遇到困境時能解決他？我的博士研究主題涉及多重領域，有一陣子，每當我遇到問題時，我就糾纏系上相關領域的老師。我記得有一天Henry Taube( 譯註：Henry Taube在1983年因在錯合物氧化還原機制探討有重大貢獻而獲諾貝爾化學獎) 回答他不知道怎樣解決我在他的領域遇到的問題。我只是個小博三，而且我知道Taube懂得比我多1000倍(保守估計)。如果他不能解答這個問題，沒有其他人可以。 That's when it hit me: nobody did. That's why it was a research problem. And being my research problem, it was up to me to solve. Once I faced that fact, I solved the problem in a couple of days. (It wasn't really very hard; I just had to try a few things.) The crucial lesson was that the scope of things I didn't know wasn't merely vast; it was, for all practical purposes, infinite. That realization, instead of being discouraging, was liberating. If our ignorance is infinite, the only possible course of action is to muddle through as best we can. 這在當時重重的打擊我：沒人可以！這就是為什麼稱之為「研究題目」。而作為「我」的研究題目，這應該是由「我」來解決才對。一但我開始正視這個殘酷的事實，幾天後我就解決了這個問題。(其實這並非真的很難，我只需要試幾個實驗就好。) 寶貴的一課：我所不知道的事並不僅是很多，而是無限！了解這道理後，我並沒有覺得沮喪，反而獲得紓解。如果我們的無知程度是無限，唯一能做的就是盡我們所能的去搞。 I'd like to suggest that our Ph.D. programs often do students a disservice in two ways. First, I don't think students are made to understand how hard it is to do research. And how very, very hard it is to do important research. It's a lot harder than taking even very demanding courses. What makes it difficult is that research is immersion in the unknown. We just don't know what we're doing. We can't be sure whether we're asking the right question or doing the right experiment until we get the answer or the result. Admittedly, science is made harder by competition for grants and space in top journals. But apart from all of that, doing significant research is intrinsically hard and changing departmental, institutional or national policies will not succeed in lessening its intrinsic difficulty. 我認為我們的博士班課程常會對學生的養成幫倒忙。首先，我不認為學生天生就了解他們所作的研究有多難，而作重要的研究更是靠背難。這比修最重的課也難得多。研究會難是因為其沉浸在未知中。我們不知道我們正在做甚麼，我們也不確定是不是問了個對的問題或是做了對的實驗，直到我們得到了結果。無可否認地，科學在經費有限與發表頂尖期刊的競爭下更形艱辛。但把這部分抽離，做擲地有聲的研究仍是他X的難，而改變系上規定、機構方針、國家政策都不會減少研究內在的難度。 Second, we don't do a good enough job of teaching our students how to be productively stupid – that is, if we don't feel stupid it means we're not really trying. I'm not talking about `relative stupidity', in which the other students in the class actually read the material, think about it and ace the exam, whereas you don't. I'm also not talking about bright people who might be working in areas that don't match their talents. Science involves confronting our `absolute stupidity'. That kind of stupidity is an existential fact, inherent in our efforts to push our way into the unknown. Preliminary and thesis exams have the right idea when the faculty committee pushes until the student starts getting the answers wrong or gives up and says, `I don't know'. The point of the exam isn't to see if the student gets all the answers right. If they do, it's the faculty who failed the exam. The point is to identify the student's weaknesses, partly to see where they need to invest some effort and partly to see whether the student's knowledge fails at a sufficiently high level that they are ready to take on a research project. 第二，我們在教育學生該如何擁有「具生產力的愚笨」仍做得不夠好。這指的是如果我們不覺得自己笨，那代表我們試的不夠勤。我並非談論「相對愚笨」，相對愚笨是指同在班上的學生確實念了書，並拿了比你好的成績。我也不是談論聰明人從事不符他們才智的工作。科學讓我們正視我們的「絕對愚笨」，這種愚笨是存在的事實，在我們嚐試把自己推向未知時便會發現。舉辦預口試與論文口試是個好構想，委員會的老師不斷的考驗學生，直到學生開始回答錯誤答案或是放棄，說「我不知道」。這些考驗的目的不是要看學生是否能正確回答各個問題。如果學生都正確的回答每個問題，那失敗的是老師而不是學生。這些考驗一部分是為了測驗學生的弱點，哪裡還需要加強；一部分是看學生所具備知識是不是能撐到很高等級的關卡才敗下陣來，看他們是否準備好接受研究計畫的挑戰。 Productive stupidity means being ignorant by choice. Focusing on important questions puts us in the awkward position of being ignorant. One of the beautiful things about science is that it allows us to bumble along, getting it wrong time after time, and feel perfectly fine as long as we learn something each time. No doubt, this can be difficult for students who are accustomed to getting the answers right. No doubt, reasonable levels of confidence and emotional resilience help, but I think scientific education might do more to ease what is a very big transition: from learning what other people once discovered to making your own discoveries. The more comfortable we become with being stupid, the deeper we will wade into the unknown and the more likely we are to make big discoveries. 具生產力的愚笨是指我們可以選擇性的忽略愚笨這件事，專注在重要的問題會讓我們很難去忽略自己的愚笨。科學美麗的其中一面是祂允許我們犯錯，一錯再錯，但當我們學到些道理時又能感覺一切都是如此完美。無庸置疑地。這對習慣甚麼問題都要能回答正確的學生很困難。無庸置疑地，一定程度的自信與情緒恢復力能幫助我們，但我想科學教育應該要做得更多：從學習別人的發現到自己發現事物有很大的鴻溝。當我們對自己的愚笨越感到自在，我們越能夠深入未知並更有機會做出重大發現。 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 75.111.128.110
