Lab Notebook: You know you are writing a paper when

Your "recently added" list in Mendeley is growing at an exponential rate:

(click to expand. note time added.)

Every new paper you read results in downloading at least two more (not unlike the Hounds of Resurrection. Coincidence? I think not).


I don't think I've ever actually finished my reading list for a paper. At some point, I shut down the process before it overwhelms my hard drive.

Since one can't be snarky in a response to a review...

I'll do it here. I am currently revising a paper for resubmission. On the whole, the reviews are fairly reasonable, with the exception of one cranky comment from a reviewer who complains that our literature review is woefully incomplete. This incompleteness seems to be our failure to cite one particular study. The reviewer writes
It is possible that this work is flawed, but it really should be discussed.
It does seem to be a relevant study and we would have cited it, had we known about it. Why didn't we know about it? Because it has never been published. It hasn't even been presented at any of the normal psycholinguistics conferences (though it has appeared at some linguistics conferences). Short of emailing every researcher who might be conducting a study that might be relevant, I'm not sure what this reviewer was expecting of us.

I'd also love to know what the folks who are obsessed with only citing studies published in peer-reviewed journals would say. (It's possible that some of these conferences it has been presented at have pretty thorough review procedures; I wouldn't know.)

Someday we will hopefully have good dictation software. For now, there is Dragon Dictate

Mary Grover at Salon has distilled the essence of using Dragon Dictate into a brief post. I couldn't possibly do better -- or even as well -- so I refer you to it.

I was assured by several people that if I continued to use DragonDictate and use the vocabulary training feature, eventually the software would learn to do a better job. I made sure to diligently train Dragon on everything that I wrote. Unfortunately, it appears that training function itself is broken. I was suspicious that even when I used very unusual words, it always insisted that it already knew all those words. So I tested it by training on a set of made-up words. When Dragon happily announced that it already knew all of those words, too, I wrote an e-mail to technical support.
I wasn't very optimistic about hearing from technical support, since they had not replied to my previous e-mails when I have had other questions. This time, they replied promptly to tell me the technical support had expired, but that I could pay for extended technical support. Presumably, if I were to pay, they would go back to not answering e-mails.
I spend a lot of time at the computer, and I bought Dragon so that I wouldn't have to spend all of that time typing. I pace when I think, but pacing and typing don't mix. I thought Dragon would give me more flexibility. As of yet, this remains a distant dream.

More on DragonDictate

DragonDictate continues to do a decent job of writing my email, so long as I don't talk about work. For writing papers, etc., it continues to be of limited use.

I was just dictating notes on how children learn to count. In two back-to-back sentences, I mentioned "subset-knowers". The first time, this was transcribed as "subset-members", and the second time, it was "sunset-whores".


Science, Grime and Republicans

Every time I go to Russia, the first thing I notice is the air. I would say it's like sucking on a car's exhaust pipe, but -- and this is key to my story -- the air in American exhaust pipes is actually relatively fresh. You have to image black soot spewing forth from a grimy, corroded pipe. Pucker up. [That's the first thing I notice, unless I'm in St Petersburg -- In many parts of Petersburg the smell of urine overwhelms the industrial pollution. And I say this as someone who loves Petersburg.]

So whenever I read that regulations are strangling business, I think of Russia. The trash everywhere. My friends, living in a second floor apartment, complaining how the grime that comes in through the window (they can't afford airconditioning) turns everything in the apartment grey. Gulping down breaths of sandpaper. The hell-hole that oil extraction has made of Sakhalin. Seriously, I don't know why more post-apocalyptic movies aren't shot in Sakhalin. Neither words nor pictures can describe the remnants of clear-cut, burnt-over forest -- looking at it, not knowing how long it's been like that, since such forests (I'm told) will almost certainly never grow back. It's something everybody should see once.

At least Russia has a great economy, thanks to deregulation. Or not. New Russians, of course, live quite well, but most people I know (college-educated middle class) are, by American standards, dirt poor. And even New Russians have to breath that shitty, shitty air.

Reality

Listening to people complain that environmental regulation is too costly and largely without value, you'd be forgiven for thinking such places didn't exist. You might believe that places without environmental regulations are healthy, wealthy and wise, rather than, for the most part, impoverished and with lousy air and water.

This is the problem with the modern conservative movement in the US, and why I'm writing this post in a science blog. Some time ago, conservatives had a number of ideas that seemed plausible. It turns out, many of them were completely wrong. The brightest of the bunch abandoned these thoroughly-discredited ideas and moved on to new ones. Others, forced to choose between reality and their priors, chose the priors.

The most famous articulation of this position comes from an anonymous Bush aid, quoted by Ron Suskind:
The aide said that guys like me were "in what we call the reality-based community," which he defined as people who "believe that solutions emerge from your judicious study of discernible reality." ... "That's not the way the world really works anymore," he continued. "We're an empire now, and when we act, we create our own reality. And while you're studying that reality—judiciously, as you will—we'll act again, creating other new realities, which you can study too, and that's how things will sort out. We're history's actors…and you, all of you, will be left to just study what we do."
Even More Reality

It doesn't stop there. Discretionary government spending, one hears, is the cause of our deficits, despite the fact that the deficit is larger than all discretionary government spending. Tax breaks for the rich stimulate the economy, whereas infrastructure improvements are useless. Paul Krugman's blog is one long chronicle of absurd economic fantasy coming from the Right.

Gay marriage harms traditional marriage -- despite the fact that places where gay marriage and civil unions exist (e.g., New England) tend to have lower divorce rates and lower out-of-wedlock birth rates.

European-style medicine is to be avoided at all costs, despite the fact that the European medical system costs less and delivers better results than the American system.

Global warming. Evolution. And so on.

A Strong Opposition

I actually strongly believe in the value of a vibrant, healthy opposition. In my work, I prefer collaborators with whom I don't agree, on the belief that this tension ultimately leads to better work. Group-think is a real concern. There may be actual reasons to avoid a particular environmental regulation, European-style health care, a larger stimulus bill, etc. -- but to the extent that those reasons are based on empirical claims, the claims should actually be right. You don't get to just invent facts.

So in theory, I could vote for a good Republican. But even if there were to be one running for office now -- and I don't think there are any -- they'd still caucus with the self-destructive, nutters that make up most of the modern party.

This is not to say Democrats have no empirical blind spots (they seem to be just as likely to believe that nonsense about vaccines and Autism, for instance), but on the whole, Democrats believe in reality. More to the point, most (top) scientists and researchers are Democrats, which has to influence the party (no data here, but I have yet to meet a Republican scientist, so they can't be that common).

So if you believe in reality, if you believe in doing what works rather than what doesn't, if you care at all about the future of our country, and if you are eligible to vote in the US elections this Fall, vote for the Democrat (or Left-leaning independent, etc., if there's one with a viable chance of winning).

You are what you say

I recently received an email forward about AnalyzeWords.com. According to its promoters

AnalyzeWords help reveal your personality by looking at how you use words. It is based on good scientific research connecting word use to who people are.
The way the site works is that you enter in someone's Twitter handle and the site analyzes their tweets.

The forward included the following comment from someone from whom, indirectly, I got the email, saying "So far it says everyone I've looked at (people, journals, etc) is depressed, except for an account someone set up to chronicle his battle with cancer, which it classified as 'very upbeat'." I tried a handle or two myself and got similar results.

One possible conclusion is that everyone -- or, at least, everyone who uses Twitter -- is depressed. Or the theory behind the website doesn't actually work. I found a possible hint in favor of the latter hypothesis on AnalyzeWords' "The Science Behind AnalyzeWords" page:

Across dozens of studies, junk words [closed-class words like prepositions and pronouns] have proven to be powerful markers of peoples [sic] psychological states. When individuals use the word I, for example, they are briefly paying attention to themselves. People experiencing high levels of physical or mental pain automatically orient towards themselves and begin using I-words at higher rates. I-use, then, can reflect signs of depression, stress or insecurity.
Perhaps. Or perhaps they're using Twitter to talk about themselves and their latest experiences.

Lean Times come to the World's Richest University

Academia is traditionally a good place to wait out recessions. Not so much this year. Harvard has posted a list of cost-cutting measures. Notice in particular that the number of PhD students being admitted has been reduced (no word about masters or professional school students...but then masters and professional school students pay tuition).

Are we more moral than cavemen?

Over the weekend, Eric Posner of Slate asked whether humans have become any more moral in the last few thousand years. His target was opinion leaders (most recently, David Brooks) who decry a moral decline in our society.

Posner asks if opinion leaders have been making such statements since the beginning of time (I believe they have, but I couldn't track down the right citation), and whether if we are to take from that fact that we as humans are far less moral than our caveman ancestors.

Posner suspects that we are at least as moral as our ancestors. I'm not sure if there is good data on morality (definition would be the first problem in that study), but there is good evidence in terms of violence.

In pre-state societies, about 60% of men die in violence. Since the Middle Ages, the murder rate in Europe has fallen a hundredfold. A smaller proportion of the human population died due to violence in the 20th century than in any previous century (yes, that's including both world wars and Stalin).

The first two of the factoids above come from The Blank Slate by Steven Pinker. Chapter 17 is particularly relevant. 

Publishing papers is slow

The bread and butter of scientific communication is the peer-reviewed journal. For those who are not familiar with the process, when a scientist (me for instance) wants to report some data, he writes it up and sends it to a journal. The editors of the journal ask a few other scientists who are experts in the same field to read the article and decide if it's any good.

This process has been criticized for being arbitrary and for being unable or unwilling to catch fraud. For all that, I honestly believe that peer review serves to improve the quality of papers. At least in psychology, it is rare for a journal to accept a paper on the first round. Instead, the reviewers suggest changes and additional experiments. Since they are experts in the field and bring a fresh eye to the problem, they often have good ideas.

There is one issue with peer review, however, that drives me nuts. That is how long the process takes. In January, a collaborator and I submitted short paper to a journal that promises extra-fast reviews of short papers. Three months later, we our expected rejection along with suggestions from the reviewers.

The thing is, in the three months that have passed, we've gotten busy with other things. I had to reread the paper a few times because I had forgotten all the details (for some reason, January feels like it was years ago). I spent the last week figuring out how to edit the experiment software, because it required some fancy programing that I had forgotten how to do.

Without further complaining, I'd like to announce the re-launch of The Video Experiment. If you have already participated (this is the only experiment I have ever run that involved a video), please do not participate in this version.* First of all, you'll be bored, because this is only a slight variation on the old experiment, and the video is the same. But more importantly, knowing what the experiment is about could affect your results.

That said, if you've never participated in the video experiment -- if you've never seen the "Bill et John" video or the "Kiwi" bird animation, you haven't participated -- please do so. It only takes 5-7 minutes, and it's easily the most entertaining experiment I've run online. Plus you get to see your own results at the end. With any luck, I can collect all the data we need within a few weeks, and then we can resubmit this paper.



*If you really want to participate, go ahead, but be sure to mark on the demographic form that you participated in the past.

The Heat Death of Science

Several years ago, I was fairly up-to-date on dyslexia research. A couple colleagues and I were writing a comprehensive review of the literature. Several drafts of the pape were written, but for various reasons that project got put aside and was never finished.

I'm currently preparing to overhaul that paper and update it based on recent research. To put this in perspective, 147 papers on dyslexia were published in 2007 alone (according to PsychInfo*).

Like the physical universe, the universe of knowledge has been expanding at an accelerated rate. It's hard to be current in several fields. By the time you are current in psychology, sociology has moved on. With time, it seems increasingly difficult to stay on top of multiple subfields (e.g., autism and dyslexia).

I wonder how long it will be before it is impossible to stay on top of even a single, narrow topic. This postulated moment would be the equivalent of heat death for science. Or not. Perhaps science will end in a big crunch instead.

Or will we find ways of dealing with massive amounts of information. While our technologies in this arena have improved, I take it as self-evidence that they have not improved as fast as information has increased.

Thoughts?

*If anybody for some reason wants to check for themselves, I searched for papers with the word "dyslexia" in the abstract. If you search for "dyslexia" in any field, you get 177.
