I’ve discussed the weirdly high intelligence of parrots before, but here’s more evidence that birds can be quite brilliant — and even have a “theory of mind”. A theory of mind is the ability to understand that other beings are sentient and have their own personal thoughts. Children generally develop this at 18 months, and you can because they learn to follow the gaze of another person and understand something about the gazer’s thoughts and internal state.
Pretty sophisticated, eh? Except that a couple of British scientists recently did “theory of mind” experiments with ravens and found that they, too, seemed to be able to grok complex stuff about a human gazer. More interestingly, raven seem to know when other ravens are checking them out, and are able to dissemble and deceive. As The Economist reports, one scientist noticed a particularly weird interaction between two ravens, one dominant and one subordinate:
The task was to work out which colour-coded film containers held some bits of cheese, then prise the containers open and eat the contents. The subordinate male was far better at this task than the dominant. However, he never managed to gulp down more than a few pieces of the reward before the dominant raven, Munin, was hustling him on his way. Clearly (and not unexpectedly) ravens are able to learn about food sources from one another. They are also able to bully each other to gain access to that food.
But then something unexpected happened. Hugin, the subordinate, tried a new strategy. As soon as Munin bullied him, he headed over to a set of empty containers, prised the lids off them enthusiastically, and pretended to eat. Munin followed, whereupon Hugin returned to the loaded containers and ate his fill.
At first Dr Bugnyar could not believe what he was seeing. He was anxious about sharing his observation, for fear that no one would believe him. But Hugin, he is convinced, was clearly misleading Munin.

V. A. To me death seems to be an evil.
M. What, to those who are already dead? or to those who must die?
A. To both.
M. It is a misery, then, because an evil?
A. Certainly.
M. Then those who have already died, and those who have still got to die, are both miserable?
A. So it appears to me.
M. Then all are miserable?
A. Every one.

One of the more interesting trends is family, which came in at number five. Specifically, discussion about family, moms, dads, daughters, etc. jumped during 2009. With Facebook users getting older, this isn’t a big surprise. However, the fact that the mention of “kids” jumped by a factor of five this year is rather dramatic. It’s tough to know what this means, though. (via Facebook Unveils Most-Mentioned Topics of 2009

BEYOND AWESOME. They are announcing a recall of the Plush Uterus “due to a potential choking hazard for children”. To apply for it, “Please send an email to the address below with the subject line, ‘UTERUS OPT OUT’”.

“To order, please TYPE “YES” IN CHECKBOX BELOW TO AGREE YOU UNDERSTAND THIS PLUSH MUST BE KEPT AWAY FROM KIDS (it is a sex organ, after all). If it is not checked, WE WILL NOT SEND THE UTERUS.” (via @ibogost)
