  • FWIW I used to hang out with behavioral psychology grad students, who were in the Skinnerian tradition of operant conditioning research. They mostly worked with pigeons, and to transport the birds they used juice pitchers with a few air holes cut into the bottom. I asked them once how they got the birds into the pitchers and they laughed and showed me: they would just open the bird’s cage and hold the pitcher up and the birds would dive head-first into the pitcher, sometimes knocking themselves out in the process.

    As part of the research protocol, the birds were kept on a diet that included about 80% of their normal caloric intake; the rest of their food was provided by the reinforcements of the experiments themselves (this was done to maximize the reinforcement effect of the rewards). So those birds were way the fuck into those experiments. To add to that, these students were all behavioral pharmacologists, so in addition to getting food reinforcement the birds were also getting drugs like cocaine and heroin.

    BTW a lot of people confuse the operant conditioning research with the people who put animals into cages and shock them. This is definitely not what BF Skinner was all about. In fact he wrote books on the subject of how punishment is a bad thing for all animals (including humans and pigeons).



  • One under-appreciated aspect of leaf design is that in addition to being able to spread out and absorb sunlight, they also need to be of a shape such that in a strong wind they tend to curl up on themselves and provide a minimum of wind resistance. Otherwise their collective sail effect would tend to uproot the tree. Fortunately, there are lots of beautiful ways to solve these related problems.






  • TBF the dropping of the bombs on Hiroshima and Nagasaki was immediately preceded by far larger slaughters of humanity using more conventional methods, a fact which somewhat minimizes their significance. I’m referring mainly to the Holocaust and the Japanese genocide in China, but even the US firebombing of Tokyo in early 1945 exceeded the death tolls of the atomic bombings.

    I walked into my break room at work a couple of years ago and overheard some of my female coworkers complaining about the formula shortage. I asked if they’d ever thought about breastfeeding and they looked at me like I’d just grown a second head. I get that some women here and there might need a supplement for this, but the idea that feeding babies canned formula should be the norm is completely insane.
