Jokes That Don’t Work

Genome Biology published a satirical piece by Neil Hall today, and since I’m American and he’s British I don’t find it funny. No wait, it’s that I’m female and he’s male. Or maybe that I’m junior and he’s senior. I’ve got it, it’s because he has a ton of publications (many times the number I have), and I have a ton of Twitter followers (many times the number he has). Meaning, my K-index knocks his out of the park.

Let me back up. You see, Hall created a joke metric he calls the Kardashian Index, which is one’s Twitter followers divided by one’s scientific citations. He writes:

“Hence a high K-index is a warning to the community that researcher X may have built their public profile on shaky foundations, while a very low K-index suggests that a scientist is being undervalued.”

Hall selected a non-random sample of 40 scientists, only 14 of whom were women. He never explains the methods of how he chose these 40. Hall himself says he “had intended to collect more data but it took a long time and I therefore decided 40 would be enough to make a point. Please don’t take this as representative of my normal research rigor.” Why be rigorous and recruit equally when it’s just social science research, amirite?

In the discussion, Hall observes that the 14 female scientists he sampled tended to have a low K-index, meaning they were underappreciated for their work. He rather nonchalantly throws this bone out there to show he’s on the side of the ladies. Strangely, many ladies have not taken up the bone and its rather meager gristle, a sign, Janet Stemwedel once pointed out, that the joke-teller isn’t as aware of his in-group as he might think.

I feel the need to draw the reader’s attention, again, to the question of how to make jokes work. As Emily Finke pointed out in a conversation with me recently, this joke punches down. How is this punching down? Consider the community. The people with power tend to be the ones who:

  • Are dubious of any time spent doing outreach, science communication, education, or social media.
  • Are scientists in fields considered more “hard,” like engineering and the physical and (some of the) life sciences.
  • Are older, white, and male.
  • Have a lot of publications.
  • Would have a K-index near or at zero.

That means that a joke intended to problematize how we quantify metrics in academic science should probably punch in that direction. Instead, Hall punches at people with less power, who tend to be:

  • Committed to social media outreach.
  • Are scientists in fields considered less “hard,” like (some of the) life and the social sciences.
  • Younger, less white, and less male.
  • Have fewer publications.
  • Have a higher K-index than you.

So yes, he’s punching down, and that makes it not funny. There is no dark corner of academic metrics to expose when the people you’re mocking are the ones least well positioned to respond. I would never have gotten that paper published – in a journal with an impact factor of 10.5, no less – because I am one of ones whose profile is built on “shaky foundations.”

All I can do… is blog about it.

Off to bloggier pastures: bringing ladybusiness to the SciAm Network

If you’re on Twitter or read any other science blogs, by now you know that the Scientific American Blog Network has launched. And, I’m pleased to say that I am a part of it! Context and Variation has moved to new digs, surrounded by a network full of bright, interesting people with great communities and great things to say.

But of course, while I encourage you to check out Bora’s post where he introduces every one of us, I have to plug a few bloggers in particular.

First, the University of Illinois is the only university to be represented by three bloggers on this new network (yeah, we totally did a press release for it). Alex Wild of Myrmecos (you know, the guy who comes up if you just google insect photography) has created a blog called Compound Eye that will cover science photography. What’s exciting about this blog is that Alex, true to his nature, will be very generous with his space and will showcase the work of many other photographers.

Joanne Manaster, who you may know as sciencegoddess on Twitter, hosts the blog Joanne is a truly exceptional science educator and puts great attention on reaching young audiences, from exploding gummy bears, the science of makeup, and Kids Read Science programs. On the SciAm blog network, Joanne will be co-hosting a new blog PsiVid with Carin Bondar. This blog will continue Joanne’s work of thinking about engaging audiences and getting them interesting in science in new ways.

In addition to these great U of I bloggers, I also have to mention my fellow anthropologists. Krystal D’Costa is moving her fantastic blog Anthropology in Practice to SciAm. You can expect more thoughtful, detailed, yet readable and fun posts from Krystal. She is a wonderful observer of human nature, and I love how she forces me to be an anthropologist at all sorts of casual moments when I usually take my academic lenses off.

Then there is Eric Michael Johnson’s blog The Primate Diaries. Eric is another very talented writer, sharing insights from a great mind. I have enjoyed his posts on sexuality, primatology, sexism, and human evolution.

Oh, and need I even mention? There are lots of female bloggers on this new, kickass network. Check out The Mary Sue’s coverage. They’re right. The SciAm Blog Network does introduce us to about a zillion new women in the sciences. Incidentally, it does a pretty decent job of introducing readers to people of varying sexualities and ethnicities as well. We can always do better, but it is a strong start.

The people of this network have exceptional voices and important perspectives. And now more people will see what they have to offer. I hope you’ll all join me over at my new place, that you’ll check out the rest of my network peeps, and that you will enjoy helping me bring the ladybusiness to Scientific American.

Summer of the pill: Will the pill mess up my ability to detect my One True Love?

Should I advise recently single ScarJo to stay
off the pill to find her next beau? From here.

Imagine you are a single, heterosexual woman. You meet a nice man at the driving range, or on a blind date. You like him and he likes you. You date, you get engaged, you get married. You decide to have a child together, so you go off the pill. One morning you wake up and look at your husband, and it’s like seeing him through new eyes. Who is this stranger you married, and what did you ever see in him?

After some articles made the news when they suggested mate preferences change on hormonal contraception, this seemed to be the scenario in the heads of many women. Is my pill deceiving me? What if my birth control is making me date the wrong man?

Several articles over the years have demonstrated that women prefer men with more masculine features at midcycle, or ovulation, and more feminine features in less fertile periods. Based on body odor, women and men also often prefer individuals with MHC (major histocompatibility complex) that are different from theirs, which may be a way for them to select mates that will give their offspring an immunological advantage. These findings have been replicated a few times, looking at a few different gendered traits. And as I suggested above, other work has suggested that the birth control pill, which in some ways mimics pregnancy, may mask our natural tendency to make these distinctions and preferences, regarding both masculinity and MHC (Little et al. 2002; Roberts et al. 2008; Wedekind et al. 1995).

On the one hand, I think it’s both interesting and important to consider the implications of the birth control pill beyond just contraception. Hormones are messages, so any cells that have receptors for these messages, like specialized mailboxes, can receive them. The pill is made of synthetic versions of estradiol and progesterone, and there are estradiol and progesterone receptors in your brain. And yes, these hormones do change your brain, both during the natural cycle and on hormonal contraception; Scicurious has written well on this in the past.

Jolie, had she been on the pill and chosen her mate
differently. From here. Yes, looks to be a real pic.

On the other hand, I have a lot of questions: First and most important to me, how does any of this translate to non-straight women? I find the constant focus on mate choice between men and women a bit exhausting, and am not sure we can assume non-straight relationships to work the same way. Next, how well do preferences over the cycle map on to actual choices for mates, short term or long term? If we happen to find Brad Pitt more attractive than Justin Bieber at midcycle, does that mean no one will do but Brad Pitt? And finally, what are all the factors that we need to consider in mate choice besides a deep voice or square jawline (again, especially if you try to expand your thinking beyond straight relationships)?

I’ll start with the last two questions that deal with mate preference versus ultimate mate selection. As you all might expect, women and men choose mates for lots of reasons, not just masculinity or complementary immune systems. Bereczkei et al (1997) looked at singles ads and found women often sought mates with high parental care. In a separate singles ad evaluation, Pawlowski and Dunbar (1999) found that women mostly selected men of high resource potential who were interested in long-term relationships (either unlikely to divorce or unlikely to die within twenty years), where men selected women by markers of fecundity (ability to have babies). In a sample of 18-24 year old straight people in the US, Buston and Emlen (2003) found that most people selected mates who had similar characteristics to themselves. And a speed dating sample showed that people under those conditions selected dates based on easily observable traits, like physical attractiveness (Kurzban and Weeden 2005).

Now on to the fact that all of this research is on straight people. I found very little on lesbian women and the menstrual cycle… but what I found was very cool! Brinsmead-Stockham et al (2008) found that, like heterosexual women, lesbian women are quicker to identify unknown faces at midcycle, as long as they were the faces of the sex they preferred. So straight women were good at identifying male faces, lesbian women good at identifying female faces. Burleson et al (2002) found that sexual behavior in lesbian and straight women was mostly similar through the menstrual cycle, with both peaking at midcycle.

So, mate preference may be about telling a research assistant who is the hottest to you at a particular point in your cycle. And it is a fairly robust and consistent finding. However, when it comes to ultimate mate selection the most important thing to consider is a great point made by Pawlowski and Dunbar: finding a mate is about advertising what you have to offer while making known what you want in a mate. Then it’s all about finding some kind of compromise through a series of trade-offs based on what the individual wants, what they can offer, and what’s available in the dating pool. (So, since neither Brad Pitt nor Justin Bieber are currently in the dating pool, my previous comparison was pointless.)

Those of you who met your mate while on the pill: not to fear. I don’t think that the possibility that you may have some suppression of masculinized preferences at one point in your cycle means you’ve chosen the wrong person.

Who knows, it could have opened you up to the Mr. or Ms. Right.
