* “Polanyi’s Paradox” - “We know more than we can tell”. The top Go players can’t fully access their own knowledge about how they’re able to perform so well. This self-ignorance is common to many human abilities, from driving a car in traffic to recognizing a face. Polanyi’s Paradox hasn’t prevented us from using computers to accomplish complicated tasks, like processing payrolls, optimizing flight schedules, routing telephone calls and calculating taxes. But as anyone who’s written a traditional computer program can tell you, automating these activities has required painstaking precision to explain exactly what the computer is supposed to do. AlphaGo, the artificial intelligence system built by the Google subsidiary DeepMind, does use simulations and traditional search algorithms to help it decide on some moves, but its real breakthrough is its ability to overcome Polanyi’s Paradox - NY Times

Financial institutions in the United States are obliged by the Gramm-Leach-Bliley Act to ensure the security and confidentiality of personal information. Complaints against violations can be filed with the FTC

Denmark and other countries which top the list of happiest countries are fairly homogeneous nations with strong social safety nets. Factors which contribute to the rankings - gross domestic product per capita (the rawest measure of a nation’s wealth); healthy years of life expectancy; social support (as measured by having someone to count on in times of trouble); trust (as measured by perceived absence of corruption in government and business); perceived freedom to make life choices; and generosity (as measured by donations)...crises can prompt vastly different responses based on the underlying social fabric. In Greece, where the economy began to plummet in 2007, setting off a crisis in the eurozone that has resulted in three financial bailouts, widespread corruption and mistrust were associated with the diminishing sense of happiness over the past decade. In contrast, trust and “social capital” are so high in Japan that scholars found, to their surprise, that happiness actually increased in Fukushima, which was devastated by an earthquake and tsunami in 2011, because an outpouring of generosity and cooperation contributed to the community’s resilience and rebuilding. - NY Times
