I was going to write about a recent study [1] on raccoons, where the adaptable little critters were given puzzle boxes to solve in order to access food rewards. On each box there were three small doors with their own distinct mechanisms, each requiring a different kind of manipulation to open. What made this study notable was that, unlike previous experiments where solved puzzles were locked out or removed to focus on new puzzles, the experimenters left the previously solved puzzles accessible to the raccoons in subsequent challenges. The raccoons were able to manipulate mechanisms that they had previously figured out, in addition to the new challenges, although they received no additional food rewards for their extra work. The upshot of the results is that the raccoons displayed an intrinsic motivation to mess around with latches, locks and doors, even when no obvious extrinsic reward was to be had. This will surprise nobody who has tried to prevent raccoons from getting into their property. There is a straightforward adaptationist explanation for this: if the animals find it psychologically rewarding to muck about with things for the fun of it, they are more likely to acquire new information and behaviours that could be useful later. Much like how the intrinsically rewarding experience of sex makes reproduction more likely.
That’s about all I have to say about the study itself, besides a slight expression of surprise that nobody had tried this before, but that’s quite common in experimental science. It’s all too easy for bystanders like me to claim that something should have been obvious, after the fact. Still, a promising avenue for future experiments to probe the exploratory and recreational side of animal problem-solving. As someone who watches a lot of mechanical engineering nerdery, much of which is more squarely in the category of “play” than necessity, it is intriguing to think that this drive to idly faff about with the physical environment is shared across the wider animal kingdom. The hedonic value of repeating known solutions is interesting, too. Read more »

What makes a city? What gives a place its distinct character? I think of the slogan ‘dilwalon ki dilli’ – the supremely banal play on words. It works in the context of Delhi only because of a happy conjunction of the word dil, or heart, with the Hindi word for the city – ‘Dilli’. It works also because it simultaneously tells us everything and nothing. Okay, people in Delhi have hearts; though this might be disputed by many who live precarious lives in this city, the marginalized, the victims of the violence the state and citizens alike often perpetrate on them. In any event, do people in other cities not have large hearts? Still, it is a catchphrase that makes those of us who live in the city feel good about ourselves. As Delhi’s most famous poet would have said, “dil ke khush rakhne ko Ghalib yeh khayal achchha hai” – it is a thought that keeps us happy.
For about 450 years, the western European colonial powers shit all over the world in spectacular fashion. Genocide across the Americas and the trans-Atlantic slave trade were the main drivers during the first phase. By the mid-19th century, European colonialism was approaching its bloody apogee with more genocide in Australia, the carving up of much of Asia, and eventually the scramble for Africa.
