      In today’s political climate, it sometimes feels like we can’t even agree on basic facts. We bombard each other with statistics and figures, hoping that more data will make a difference. A progressive person might show you the same climate change graphs over and over while a conservative person might point to the trillions of dollars of growing national debt. We’re left wondering, “Why can’t they just see? It’s so obvious!”

      Certain myths are so pervasive that no matter how many experts disprove them, they only seem to grow in popularity. There’s no shortage of serious studies showing no link between autism and vaccines, for example, but these are no match for an emotional appeal to parents worried for their young children.

      Tali Sharot, a cognitive neuroscientist at University College London, studies how our minds work and how we process new information. In her upcoming book, The Influential Mind, she explores why we ignore facts and how we can get people to actually listen to the truth. Tali shows that we’re open to new information – but only if it confirms our existing beliefs. We find ways to ignore facts that challenge our ideals. And as neuroscientist Bahador Bahrami and colleagues have found, we weigh all opinions as equally valid, regardless of expertise.

      So, having the data on your side is not always enough. For better or for worse, Sharot says, emotions may be the key to changing minds.

                   the brilliance of architect Paulo Mendes da Rocha

Oliver Wainwright

February 4, 2017

   “All space is public,” says Paulo Mendes da Rocha. “The only private space that you can imagine is in the human mind.” It is an optimistic statement from the 88-year-old Brazilian architect, given he is a resident of São Paulo, a city where the triumph of the private realm over the public could not be more stark. The sprawling megalopolis is a place of such marked inequality that its superrich hop between their rooftop helipads because they are too scared of street crime to come down from the clouds.

   But for Mendes da Rocha, who received the 2017 gold medal from the Royal Institute of British Architects this week – an accolade previously bestowed on such luminaries as Le Corbusier and Frank Lloyd Wright – the ground is everything. He has spent his 60-year career lifting his massive concrete buildings up, in gravity-defying balancing acts, or else burying them below ground in an attempt to liberate the Earth’s surface as a continuous democratic public realm. “The city has to be for everybody,” he says, “not just for the very few.”

                                    Genetically modified foods

      Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism. Currently available GM foods stem mostly from plants, but in the future foods derived from GM microorganisms or GM animals are likely to be introduced on the market. Most existing genetically modified crops have been developed to improve yield, through the introduction of resistance to plant diseases or of increased tolerance of herbicides.

      In the future, genetic modification could be aimed at altering the nutrient content of food, reducing its allergenic potential, or improving the efficiency of food production systems. All GM foods should be assessed before being allowed on the market. FAO/WHO Codex guidelines exist for risk analysis of GM food.
