Introduction: There’s a lot of free advice out there. I offer some of it myself! As I’ve written before (see this post from 2008 reacting to this advice from Dan Goldstein for business school students, and this post from 2010 reacting to some general advice from Nassim Taleb), what we see is typically presented as advice to individuals, but it’s also interesting to consider the possible total effects if the advice is taken. It’s time to play the game again. This time it’s advice from sociologist Fabio Rojas for Ph.D. students. I’ll copy his eight points of advice, then, for each, evaluate whether I think it is positive or negative sum: 1. Show up. Even if you feel horrible, show up. No matter what. Period. Unless someone died in your family, show up. 2. Do your job. Grade the papers. Do the lab work. Unless the work is extreme, take it in stride. 3. Be completely realistic about how you will be evaluated from day #1 – acquire a teaching record and a record of publication. Don’t h

1 This time it’s advice from sociologist Fabio Rojas for Ph. [sent-5, score-0.436]

2 I’ll copy his eight points of advice, then, for each, evaluate whether I think it is positive or negative sum: 1. [sent-8, score-0.474]

3 Be completely realistic about how you will be evaluated from day #1 – acquire a teaching record and a record of publication. [sent-20, score-0.425]

4 Don’t have the fantasy that you will magically get the job of your dreams sans publications. [sent-21, score-0.208]

5 These people are actually pretty easy to identify – they do well in teaching and publication and they have a track record of placement. [sent-25, score-0.4]

6 Instead, if you actually offer to help and present a solution, then you’ll make a difference and people will appreciate it. [sent-31, score-0.242]

7 No excuses: the only thing that matters is task completion. [sent-37, score-0.211]

8 If you don’t show up, this inconveniences others; whereas if you’re distracted and show up and do a crappy job, this still is likely to be better than people having to cover for you or reschedule the meeting. [sent-47, score-0.391]

9 But I’d like to emphasize the last sentence of Rojas’s advice #3, and point out that, if you do something un-work-related because you care, that’s cool too. [sent-54, score-0.436]

10 Similarly, I generally recommend that students taking classes shop around and, to the extent possible, choose instructors with excellent teaching evaluations. [sent-57, score-0.493]

11 The signal isn’t perfect but it’s there (in my impression), and it also has generally positive effects in the sense of encouraging instructors to try harder and take their teaching more seriously. [sent-58, score-0.622]

12 This advice could be positive or negative sum, depending on how it’s taken. [sent-60, score-0.91]

13 If someone reads this advice and is encouraged to be constructive and help people, this is positive. [sent-61, score-0.706]

14 But if someone reads this advice and is discouraged from offering frank criticism, I think it could be negative. [sent-62, score-0.673]

15 I disagree with Rojas’s statement that criticism alone “really doesn’t accomplish much. [sent-64, score-0.22]

16 ” It might not seem to be accomplishing much, but if you can save someone a year of effort by pointing out they’re on the wrong track, that can be a big deal! [sent-65, score-0.142]

17 I’ve seen so many students say they’re too busy to take on a new project, and what does it get them? [sent-70, score-0.148]

18 On one hand, everyone benefits when a task is completed. [sent-74, score-0.189]

19 On the other hand, we can all benefit from when we help each other understand things, so if people literally follow the advice that “the only thing that matters is task completion,” this could make like more difficult for everyone. [sent-75, score-0.879]

20 Ok, in sum, that’s 6 points on the positive side and 2 on the negative side. [sent-83, score-0.474]

2 0.27416262 278 andrew gelman stats-2010-09-15-Advice that might make sense for individuals but is negative-sum overall

Introduction: There’s a lot of free advice out there. As I wrote a couple years ago, it’s usually presented as advice to individuals, but it’s also interesting to consider the possible total effects if the advice is taken. For example, Nassim Taleb has a webpage that includes a bunch of one-line bits of advice (scroll to item 132 on the linked page). Here’s his final piece of advice: If you dislike someone, leave him alone or eliminate him; don’t attack him verbally. I’m a big Taleb fan (search this blog to see), but this seems like classic negative-sum advice. I can see how it can be a good individual strategy to keep your mouth shut, bide your time, and then sandbag your enemies. But it can’t be good if lots of people are doing this. Verbal attacks are great, as long as there’s a chance to respond. I’ve been in environments where people follow Taleb’s advice, saying nothing and occasionally trying to “eliminate” people, and it’s not pretty. I much prefer for people to be open

Introduction: Sociologist Fabio Rojas reports on “a conversation I [Rojas] have had a few times with statisticians”: Rojas: “What does your research tell us about a sample of, say, a few hundred cases?” Statistician: “That’s not important. My result works as n–> 00.” Rojas: “Sure, that’s a fine mathematical result, but I have to estimate the model with, like, totally finite data. I need inference, not limits. Maybe the estimate doesn’t work out so well for small n.” Statistician: “Sure, but if you have a few million cases, it’ll work in the limit.” Rojas: “Whoa. Have you ever collected, like, real world network data? A million cases is hard to get.” The conversation continues in this frustrating vein. Rojas writes: This illustrates a fundamental issue in statistics (and other sciences). One you formalize a model and work mathematically, you are tempted to focus on what is mathematically interesting instead of the underlying problem motivating the science. . . . We have the sam

4 0.19847856 1428 andrew gelman stats-2012-07-25-The problem with realistic advice?

Introduction: In an article entitled 16 Weeks, Thomas Basbøll ruthlessly lays out the time constraints that limit what a student will be able to write during a semester and recommends that students follow a plan: Try to be realistic. If you need time for “free writing” or “thought writing” (writing to find out what you think) book that into your calendar as well, but the important part of the challenge is to find time to write down what you already know needs to be written. If you don’t yet know what you’re going to say this semester, then your challenge is, in part, to figure that out. But you should still find at least 30 minutes a day to write down something you know you want to say. Keep in mind that we are only talking about sixteen weeks in the very near future. . . . Assuming that you do have something say, then, here’s the challenge: write always and only when (and what) your calendar tells you to. Don’t write when “inspired” to do so (unless this happens to coincide with your writing s

Introduction: This blog is an exercise in scalability. Instead of sending a long email to one person, I put the email in a blog where thousands can read it. Instead of devoting three hours to a referee report that will only be read by two people (the author and the journal editor), I do the equivalent here on the blog. When the American Statistical Association asked me to participate in a workshop to give writing advice for a select group of young researchers, I agreed to participate in this program, as long as the authors were willing to have their articles and my comments posted on the blog. I think my advice on writing research articles had much more effect being posted on the web than it would’ve had, if I’d kept it in that meeting. (On the other hand, my advice benefited from having those two student papers to push against. If I’d just tried to give general advice without the context, I don’t think it would’ve been so useful to anyone.) I’ve tried to be scalable for many years before

2 0.86606157 592 andrew gelman stats-2011-02-26-“Do you need ideal conditions to do great work?”

Introduction: John Cook links to a blog by Ben Deaton arguing that people often waste time trying to set up ideal working conditions, even though (a) your working conditions will never be ideal, and (b) the sorts of constraints and distractions that one tries to avoid, can often stimulate new ideas. Deaton seems like my kind of guy–for one thing, he works on nonlinear finite element analysis, which is one of my longstanding interests–and in many ways his points are reasonable and commonsensical (I have little doubt, for example, that Feynman made a good choice in staying clear of the Institute for Advanced Study!), but I have a couple of points of disagreement. 1. In my experience, working conditions can make a difference. And once you accept this, it could very well make sense to put some effort into improving your work environment. I like to say that I spent twenty years reconstructing what it felt like to be in grad school. My ideal working environment has lots of people coming in

4 0.84481519 515 andrew gelman stats-2011-01-13-The Road to a B

Introduction: A student in my intro class came by the other day with a lot of questions. It soon became clear that he was confused about a lot of things, going back several weeks in the course. What this means is that we did not do a good job of monitoring his performance earlier during the semester. But the question now is: what do do next? I’ll sign the drop form any time during the semester, but he didn’t want to drop the class (the usual scheduling issues). And he doesn’t want to get a C or a D. He’s in big trouble and at this point is basically rolling the dice that he’ll do well enough on the final to eke out a B in the course. (Yes, he goes to section meetings and office hours, and he even tried hiring a tutor. But it’s tough–if you’ve already been going to class and still don’t know what’s going on, it’s not so easy to pull yourself out of the hole, even if you have a big pile of practice problems ahead of you.) What we really need for this student, and others like him, is a road

2 0.98419636 902 andrew gelman stats-2011-09-12-The importance of style in academic writing

Introduction: In my comments on academic cheating , I briefly discussed the question of how some of these papers could’ve been published in the first place, given that they tend to be of low quality. (It’s rare that people plagiarize the good stuff, and, when they do—for example when a senior scholar takes credit for a junior researcher’s contributions without giving proper credit—there’s not always a paper trail, and there can be legitimate differences of opinion about the relative contributions of the participants.) Anyway, to get back to the cases at hand: how did these rulebreakers get published in the first place? The question here is not how did they get away with cheating but how is it that top journals were publishing mediocre research? In the case of the profs who falsified data (Diederik Stapel) or did not follow scientific protocol (Mark Hauser), the answer is clear: By cheating, they were able to get the sort of too-good-to-be-true results which, if they were true, would be

3 0.98407531 2353 andrew gelman stats-2014-05-30-I posted this as a comment on a sociology blog

Introduction: I discussed two problems: 1. An artificial scarcity applied to journal publication, a scarcity which I believe is being enforced based on a monetary principle of not wanting to reduce the value of publication. The problem is that journals don’t just spread information and improve communication, they also represent chits for hiring and promotion. I’d prefer to separate these two aspects of publication. To keep these functions tied together seems to me like a terrible mistake. It would be as if, instead of using dollar bills as currency, we were to just use paper , and then if the government kept paper artificially scarce to retain the value of money, so that we were reduced to scratching notes to each other on walls and tables. 2. The discontinuous way in which unpublished papers and submissions to journals are taken as highly suspect and requiring a strong justification of all methods and assumptions, but once a paper becomes published its conclusions are taken as true unless

4 0.98339736 1848 andrew gelman stats-2013-05-09-A tale of two discussion papers

Introduction: Over the years I’ve written a dozen or so journal articles that have appeared with discussions, and I’ve participated in many published discussions of others’ articles as well. I get a lot out of these article-discussion-rejoinder packages, in all three of my roles as reader, writer, and discussant. Part 1: The story of an unsuccessful discussion The first time I had a discussion article was the result of an unfortunate circumstance. I had a research idea that resulted in an article with Don Rubin on monitoring the mixing of Markov chain simulations. I new the idea was great, but back then we worked pretty slowly so it was awhile before we had a final version to submit to a journal. (In retrospect I wish I’d just submitted the draft version as it was.) In the meantime I presented the paper at a conference. Our idea was very well received (I had a sheet of paper so people could write their names and addresses to get preprints, and we got either 50 or 150 (I can’t remembe

5 0.98297024 1435 andrew gelman stats-2012-07-30-Retracted articles and unethical behavior in economics journals?

Introduction: Stan Liebowitz writes: Have you ever heard of an article being retracted in economics? I know you have only been doing this for a few years but I suspect that the answer is that none or very few are retracted. No economist would ever deceive another. There is virtually no interest in detecting cheating. And what good would that do if there is no form of punishment? I say this because I think I have found a case in one of our top journals but the editor allowed the authors of the original article to write an anonymous referee report defending themselves and used this report to reject my comment even though an independent referee recommended publication. My reply: I wonder how this sort of thing will change in the future as journals become less important.
