Psychology
drorzel | April 14, 2015I continue to struggle to avoid saying anything more about the Hugo mess, so let's turn instead to something totally non-controversial: gender bias in academic hiring. Specifically, this new study in the Proceedings of the National Academy of Science titled "National hiring experiments reveal 2:1 faculty preference for women on STEM tenure track" with this calm, measured abstract that won't raise any hackles at all:
National randomized experiments and validation studies were conducted on 873 tenure-track faculty (439 male, 434 female) from biology, engineering, economics, and psychology at…
drorzel | February 4, 2015Probably the dumbest person I've ever met in my life was a housemate in grad school. I didn't do my lab work on campus, so I wasn't living in a neighborhood where cheap housing was rented to students, but in a place where folks were either genuinely poor, or in the market for very temporary lodgings while they looked for something better. There were low-income housing units across the street, and also an apartment building full of families who didn't quite qualify for welfare.
This particular guy rented one of the other rooms in the house, and worked a series of unskilled jobs-- assistant on…
drorzel | June 16, 2014The latest in a long series of articles making me glad I don't work in psychology was this piece about replication in the Guardian. This spins off some harsh criticism of replication studies and a call for an official policy requiring consultation with the original authors of a study that you're attempting to replicate. The reason given is that psychology is so complicated that there's no way to capture all the relevant details in a published methods section, so failed replications are likely to happen because some crucial detail was omitted in the follow-up study.
Predictably enough, this…
drorzel | April 12, 2013One of the hot topics of the moment is the E. O. Wilson op-ed lamenting the way math scares students off from science, and downplaying the need for mathematical skill (this is not news, really-- he said more or less the same thing a few years ago, but the Wall Street Journal published it to promote his upcoming book). This has raised a lot of hackles in the more math-y side of the science blogosphere, while some in less math-y fields (mostly closer to Wilson's home field of evolutionary biology) either applaud him or don't see what the fuss is about.
The split, I think, comes from the fact…
drorzel | May 31, 2011A bunch of people I follow on social media were buzzing about this blog post yesterday, taking Jonah Lerher to task for "getting spun" in researching and writing this column in the Wall Street Journal about this paper on the "wisdom of crowds" effect. The effect in question is a staple of pop psychology these days, and claims that an aggregate of many guesses by people with little or no information will often turn out to be a very reasonable estimate of the true value. The new paper aims to show the influence of social effects, and in particular, that providing people with information about…
drorzel | April 21, 2011After chasing a bunch of kids with cell phones off of his lawn, Kevin Drum has kicked off a discussion of "multitasking", specifically about whether it's merely a threat, or a positive menace. He points to an interview with Clifford Nass, a researcher who says his experiments show that nobody is any good at doing two things at once. John Holbo at Crooked Timber picks up the discussion and adds a few good points, and there are some others in the comments (CT's comment section being one of the most civilized and erudite in blogdom).
In particular, I think John's comment on satisficing is an…
drorzel | November 1, 2010In last weekend's post about arguments from innate differences, I suggested that I might be willing to illustrate my position with adorable toddler pictures. On thinking more about it, I'm a little hesitant to write about this at length, because it could easily topple over into arrogant-physicist territory. But then, it's an excuse to post adorable toddler pictures, so...
So, let me put a short disclaimer up front: I'm not attempting to claim that I have suddenly uncovered a unique and obvious flaw in innate-difference arguments, by virtue of my Big Physicist Brain. I am well aware that the…
drorzel | October 24, 2010In yesterday's post about the experience of science, I mentioned that I had both a specific complaint about the article by Alexandra Jellicoe (which I explained in the post) and a general complaint about the class in which the article falls. I want to attempt to explain the latter problem, partly because I think it will be useful, but mostly because it's stuck in my head, and I need to at least type out the explanation before I can move on to other things.
The article in question doesn't contain all of the elements I'll mention below, but I think it clearly falls into a class of articles that…
drorzel | August 30, 2010There was a deeply silly New York Times article about "Past Life Regression" over the weekend:
In one of his past lives, Dr. Paul DeBell believes, he was a caveman. The gray-haired Cornell-trained psychiatrist has a gentle, serious manner, and his appearance, together with the generic shrink décor of his office -- leather couch, granite-topped coffee table -- makes this pronouncement seem particularly jarring.
In that earlier incarnation, "I was going along, going along, going along, and I got eaten," said Dr. DeBell, who has a private practice on the Upper East Side where he specializes in…
drorzel | July 17, 2010There are lots of reasons why Josh Rosenau is one of the few writers blogging about science-and-religion issues that I still read. This morning's post on what you ought to do to determine effective approaches is an outstanding example:
Rather than looking at national polls, which are crude instruments and can miss shifts within small subpopulations, I'd think that it would be more useful to do lab work, and to look at the broader literature on communications. Daniel Loxton did a nice roundup of a few useful studies in this realm, and Mike McRae looked at a wider sampling in the context of…
drorzel | August 25, 2009I'm doing better today, but still a little wobbly, and trying to conserve my energy for the Bruce Springsteen concert tonight. Thus, a poll:
Imagine you have a light switch box containing multiple switches, like to one at right. These switches control lights in adjoining areas of the house-- say, the living room, and the light on the stairs up to the bedrooms. At least one of these switches is part of a pair-- say, there's another switch at the top of the stairs controlling that light.
The question is this: when you go to bed at night, turning off all the lights, what should the position of…
drorzel | June 21, 2009Via Steve Hsu, a lengthy rant by Bruce Charlton about the dullness of modern scientists:
Question: why are so many leading modern scientists so dull and lacking in scientific ambition? Answer: because the science selection process ruthlessly weeds-out interesting and imaginative people. At each level in education, training and career progression there is a tendency to exclude smart and creative people by preferring Conscientious and Agreeable people. The progressive lengthening of scientific training and the reduced independence of career scientists have tended to deter vocational '…
drorzel | May 6, 2008A few days back, John Scalzi posted a piece celebrating YA books and authors, which included some reading recommendations. In the comments, a few people said that as childless adults they were reluctant to go into the YA section of the store, lest people think they were creeps looking for kids to prey upon.
I can honestly say that that would just never occur to me. I can't really imagine how skeevey somebody would need to look before I thought "Gee, I wonder if that guy is really a pedophile creep?" rather than "There's a guy looking for books for his kid."
Of course, the sad thing is that…
drorzel | February 28, 2008EurekAlert tossed up a press release from the University of Minnesota yesterday with the provocative title: "U of Minn researchers find primary alcohol prevention programs are needed for 'tweens'" and the even more eye-popping subtitle "Study recommends that prevention programs occur as early as third grade." What, you may ask, is the problem this is intended to solve?
The study found that adolescents who already use alcohol are less receptive to prevention programs aimed at all students. Intervening at earlier ages, specifically between third and fifth grade, would allow for truly universal…
drorzel | October 26, 2007Over at Neurophilosophy, Mo links to an article by a physicist, posted on the arxiv, that claims to explain visual perceptions using quantum mechanics:
A theory of the process of perception is presented based on von Neumann's quantum theory of measurement and conscious observation. Conscious events that occur are identified with the quantum mechanical ``collapses'' of the wave function, as specified by the orthodox quantum theory. The wave function, between such perceptual events, describes a state of potential consciousness which evolves via the Schr\"odinger equation. When a perceptual…
drorzel | October 18, 2007I'm not sure whether it was prompted by James Watson's little outburst (for which he has apologized "unreservedly") or just serendipity, but Cosma Shalizi offers an exhaustive demolition of the idea of a single general intelligence factor:
Anyone who wanders into the bleak and monotonous desert of IQ and the
nature-vs-nurture dispute eventually gets trapped in the especially arid
question of what, if anything, g, the supposed general factor of
intelligence, tells us about these matters. By calling g a
"statistical myth" before, I
made clear my conclusion, but none of my reasoning. This…
