The career fair mentioned in the previous post began today with recruiters from business and public service; most of these were somewhat removed from what I was looking for but I dropped in to see if any of the finance people were looking for physicists. Observations:
Stick figure webcomic xkcd, which was discussed in a recent open thread, is now selling t-shirts. The first one is excellent; I can't decide if the second is cute or just sad (speaking as someone who sometimes needs to make the clarification written on said shirt).
Shy children... showed two to three times more activity in their striatum, which is associated with reward, than outgoing children, the team reports in the 14 June issue of the Journal of Neuroscience. "Up until now, people thought that [shyness] was mostly related to avoidance of social situations," says co-author and child psychiatrist Monique Ernst. "Here we showed that shy children have increased activity in the reward system of the brain as well."
Regardless of whether this is really a hallmark of shyness, one thing that I've found useful in my efforts to be less shy has been to take a very analytical look at my past interactions and try to put them in the proper perspective. So instead of getting worked up about a particular conversation that went really well or really poorly, I'll realize that it was basically an unremarkable event either way. The end result (when this works) is that I stop seeing every interaction as the latest major test of my social skills, and this removes some of the attendant anxiety.
Time to revisit the ever-popular topic of introversion. There's this old Atlantic Monthly article on the subject that was discussed recently by Kevin Drum and Chad Orzel. In general I thought this article tended to overstate matters, and was overly harsh on extroverts (maybe this was intended for comic effect). For example, this paragraph:
Extroverts have little or no grasp of introversion. They assume that company, especially their own, is always welcome. They cannot imagine why someone would need to be alone; indeed, they often take umbrage at the suggestion. As often as I have tried to explain the matter to extroverts, I have never sensed that any of them really understood. They listen for a moment and then go back to barking and yipping.
How can I let the introvert in my life know that I support him and respect his choice? First, recognize that it's not a choice. It's not a lifestyle. It's an orientation.
Second, when you see an introvert lost in thought, don't say "What's the matter?" or "Are you all right?"
Third, don't say anything else, either.
In any case, one shouldn't assume that just because an introvert isn't talking, he doesn't want to be talked to. The author of the Atlantic Monthly article doesn't seem to like extroverts very much at all, but I'm the opposite: I often really enjoy conversations with talkative people, because a conversation where I'm supplying only 10% of the dialogue is a lot easier and more comfortable than one in which I need to supply 50%.
I suspect that if I weren't shy, I'd be a lot less introverted (although not quite extroverted).
As part of Battaglia's study, he collected saliva samples from his 49 subjects and analyzed their DNA, looking for something that might further explain his results. The shy children, he found, had one or two shorter copies of a gene that codes for the flow of the brain chemical serotonin, a neurotransmitter that plays a role in anxiety, depression and other mood states. Battaglia's lab is not the only one to have linked this gene to shyness, and while nobody pretends it's the entire answer, most researchers believe it at least plays a role. "People who carry the short variant of the gene are, in general, a little more shy and reactive to stress," says psychiatrist Michael Meaney of McGill University in Montreal, who just completed a two-year study of timidity and stress.
