The annual Association for Psychological Science meeting is coming up in San Francisco this week. One of the cross-cutting themes this year is “Big Data: Understanding Patterns of Human Behavior”. Since I’m giving two Big Data-related talks (1, 2), and serving as discussant on a related symposium, I’ve been spending some time recently trying to … Continue reading Big Data, n. A kind of black magic
Twitter is kind of a big deal. Not just out there in the world at large, but also in the research community, which loves the kind of structured metadata you can retrieve for every tweet. A lot of researchers rely heavily on twitter to model social networks, information propagation, persuasion, and all kinds of interesting … Continue reading estimating the influence of a tweet–now with 33% more causal inference!
This is fiction. The party is supposed to start at 7 pm, but of course, no one shows up before 8:45. When the guests finally do arrive, I randomly assign each of them to one of four groups–A through D–as they enter. Each assignment comes with an adhesive 2″ color patch, a nametag, and a … Continue reading Jirafas
Last year when I launched my lab (which, full disclosure, is really just me, plus some of my friends who were kind enough to let me plaster their names and faces on my website), I decided to call it the Psychoinformatics Lab (or PILab for short and pretentious), because, well, why not. It seemed to … Continue reading …and then there were two!
This is fiction. Science will return shortly. Cornelius Kipling doesn’t take No for an answer. He usually takes several of them–several No’s strung together in rapid sequence, each one louder and more adamant than the last one. “No,” I told him over dinner at the Rhubarb Club one foggy evening. “No, no, no. I won’t … Continue reading the seedy underbelly
Apparently time does a thing that is much like flying. Seems like just yesterday I was sitting here in this chair, sipping on martinis, and pleasantly humming old show tunes while cranking out several high-quality blog posts an hour a mediocre blog post every week or two. But then! Then I got distracted! And blinked! … Continue reading several half-truths, and one blatant, unrepenting lie about my recent whereabouts
Warning: what follows is a somewhat technical discussion of my love-hate relationship with the R statistical language, in which I somehow manage to waste 2,400 words talking about a single line of code. Reader discretion is advised. I’ve been using R to do most of my statistical analysis for about 7 or 8 years now–ever … Continue reading R, the master troll of statistical languages
I got back from the Cognitive Neuroscience Society meeting last week. I was planning to write a post-CNS wrap-up thing like I did last year and the year before that, but I seem to have misplaced the energy that’s supposed to fuel such an exercise. So instead I’ll just say I had a great time and … Continue reading in which I apologize for my laziness, but not really
Early on in graduate school, I invested in the book “How to Write a Lot“. I enjoyed reading it–mostly because I (mistakenly) enjoyed thinking to myself, “hey, I bet as soon as I finish this book, I’m going to start being super productive!” But I can save you the $9 and tell you there’s really … Continue reading on writing: some anecdotal observations, in no particular order
In the process of writing a short piece for the APS Observer, I was fiddling around with Google Correlate earlier this evening. It’s a very neat toy, but if you think neuroimaging or genetics have a big multiple comparisons problem, playing with Google Correlate for a few minutes will put things in perspective. Here’s a … Continue reading the neuroinformatics of Neopets
