Advertisers are always looking to better understand consumers’ preferences and decision making. The application of neuroscience knowledge and techniques to answer market and media research questions is not new but in our digital age, the practice raises new questions about privacy, informed consent, and consumer autonomy in decision making. Dr. Carl Marci, Chief Neuroscientist at Nielsen explores the ethical concerns that arise and explains some of the tools used by advertisers in this growing field.
As anyone who uses a computer, tablet, smart phone, or VR (virtual reality) device knows, we live in an Information Age unprecedented in human history, in which the sum total of mankind’s knowledge is available with a finger’s touch or click of a mouse – or a question posed to Alexa, Siri, Cortana, et al. This has put tremendous power in the hands of the end user, but as noted by philosophers and statesmen, with great power comes great responsibility. While navigating through this vast and ever-growing trove of data we must be (but all too often aren’t) mindful of the pitfalls and obstacles that litter the virtual pathways and take the steps necessary to avoid them.
At a time when you can search billions of texts in milliseconds, scan over trillions of online images, and map virtually the entire planet’s surface, we need to rethink what it means to be literate and to be a learner. As the very definition of “literacy” is evolving thanks to technology, so too is the skillset required by the literate person. Merely knowing how to read is no longer enough; as our methods of teaching and learning increasingly move from traditional linear modes to the non-linear forms enabled by technology, we must learn anew how to frame questions, interpret results, quickly evaluate and organize masses of information, separate the authentic from the fabricated, and above all understand and nurture our “metacognition.”
Dan Russel, Google’s Űber Tech Lead for Search Quality and User Happiness at Google (yes, that’s his official title, but he describes himself as a “cyber-tribal-techno-cognitive-anthropologist”) uses, naturally enough, various Google services and apps as models of tools that may be applied in service of metacognition. Google Search and Google Maps have become ubiquitous, but there are other information weapons in Google’s arsenal. One often overlooked example is the metadata embedded in photographs. Among other parameters metadata can indicate date, time, and location (longitude and latitude) of origin; this data can, in turn, be analyzed to determine the authenticity of a photo, obviously a useful tool at a time when deliberate misinformation constitutes a significant portion of social media posts. Many Google users may also be unaware that Google maintains a Public Data archive, containing a wide array of charts, diagrams, statistics, scientific studies, and other information.
These resources and many (many) others available via Web or app can help the user to develop “informacy,” which Russell considers the updated version of literacy. At its most basic, informacy means a) knowing what the information is, b) knowing where to find it, c) knowing how to verify it, d) knowing how to interact with it, and e) knowing how to apply and/or share it. With expanded and virtual reality technologies developing rapidly, informacy and the skills it requires will become absolutely essential.
In short, they interbred, according to Svante Pääbo, a Swedish biologist and pioneer of paleogenetics, the study of preserved genetic material from the remains of ancient organisms, including ancient human DNA. He has served as director of the Department of Evolutionary Genetics at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, since 1997.
He explains in this lecture that Neanderthals and Denisovans have a common ancestor in Africa. About half a million years ago, these species of humans came out of Africa and evolved into what we call Neanderthals in Western Eurasia and Denisovans in Eastern Eurasia. Much later modern humans appeared in Africa and then spread, initially to the Middle East, then to Eurasia where they encountered Neanderthals and Denisovans. Eventually, those earlier species became extinct, replaced by modern humans.
Pääbo’s lab famously retrieved and sequenced ancient Neanderthal DNA and produced a high-quality genome sequence that allowed for the reconstruction of the recent evolutionary history of our species. Once the genome was sequenced and studied it became apparent that ancient and modern humans interbred. In fact, most present-day humans have some Neanderthal DNA.
Svante Pääbo’s was selected by Scripps Institution of Oceanography at the UC San Diego as the recipient of the 2018 Nierenberg Prize for Science in the Public Interest. He gave this fascinating lecture on that occasion.
The results of the 2018 midterm elections are in, but what’s next? Will a Democratic-controlled House and Republican-led Senate be able to work together? What do the results mean for 2020? And, what should Democrats do to capitalize on midterm gains? Professor Emeritus Sanford A. Lakoff shared his thoughts on those questions and more at the Osher Lifelong Learning Institute at UC San Diego Extension. He begins by looking at midterm turnout, changing demographics, and increasing political polarization. He notes that many point to the Gingrich Revolution as the beginning of modern-day polarization, and suggests President Trump has only added to the trend.
But, there is also division within the Democratic Party. Several newly-elected representatives have pledged not to vote for Nancy Pelosi for Speaker of the House. Lakoff argues that would be a mistake. He cautions that the coalition risks becoming a “Tea Party of the Left” if they are unwilling to compromise, especially without holding either the Senate or the Presidency. He suggests Pelosi should pledge to only serve as Speaker until 2020, and prepare new Democratic representatives to take on leadership positions in the future.
Lakoff then lays out what he believes should be the top priorities for Democrats over the next two years. His list includes healthcare, immigration reform, climate change, and gun control. While he admits it’s unlikely Democrats will make significant progress on the issues, Lakoff says the effort would show voters what they can expect should Democrats take the Senate and White House in 2020. Lakoff also suggests lawmakers go beyond legislation, and set up think tanks and non-partisan commissions on the major issues of our time. Those include electoral reform, medical coverage, gun violence, the national debt, and ensuring employment with the development of artificial intelligence. But, the ability to make any progress on any of these issues may rest on an unpredictable variable: the Robert Mueller investigation.
