‘Now, a new study in the journal Science Advances from researchers at the University of Melbourne and the University of Cambridge — Elizabeth Bowman, David Coghill, Carsten Murawski, and Peter Bossaerts — finds that far from making users smarter, smart drugs seem to actually undermine cognitive performance.
The authors tested the effects of three drugs — methylphenidate (more commonly known through one of its brand names, Ritalin), modafinil, and dextroamphetamine* (brand name Dexedrine, among others) — on a cognitive task designed to more closely mimic the complexities of real-world problems than past stimulant studies.
Far from simply concluding that smart drugs offer little benefit, the researchers found that the drugs actually seemed to leave users worse off. While study subjects worked harder while on the drugs compared to placebo, the “quality of effort,” or productivity, actually declined. The upshot is that smart drugs led users to spend more effort working while being less productive — not exactly a picture of cognitive enhancement….’ (Vox)

‘… they found that the parrots took advantage of the opportunity to call one another, and they typically stayed on the call for the maximum time allowed during the experiment. They also seemed to understand that another live bird was on the other side of the screen, not a recorded bird, researchers say. Some of the parrots learned new skills from their virtual companions, including flying, foraging and how to make new sounds.

Although there is calculated antisocial predation, most human aggression is not rationally planned but emotionally mediated, in response to (often unconsciously evoked) threat. So reducing violence has a lot to do with increasing awareness and deliberately countering these strong Us-Them dichotomies. As Sapolsky concludes, “[G]ive the right-of-way to people driving cars with the “Mean people suck” bumper sticker…”
