On belief superiority “Finally and more promisingly, the researchers found some evidence that belief superiority can be dented by feedback. If participants were told that people with beliefs like theirs tended to score poorly on topic knowledge, or if they were directly told that their score on the topic knowledge quiz was low, this not only reduced their belief superiority, it also caused them to seek out the kind of challenging information they had previously neglected in the headlines task (though the evidence for this behavioural effect was mixed).”
Spatial navigation countrywise  “While age most strongly correlated with navigational performance, researchers also found that country wealth, as measured by GDP (gross domestic product), correlated with performance. The researchers say this relationship may be due to associations with education standards, health and ability to travel. They focused on GDP for this analysis as it was a standard metric available for every country, but as part of the ongoing research project they will follow up with further comparisons of other factors.....Comparing the country-level results to the World Economic Forum's Gender Gap Index, the researchers found a correlation between country-wide gender inequality and a larger male advantage in spatial navigation ability. The gender gap in game performance was also smaller in countries with greater economic wealth.”

Michael Hudson on whether Marx was right or wrong

Fromthree years ago The Paradox of Financialized Industrialization
All three kinds of crisis that Marx described are occurring. But the West is now in a chronic depression – what has been called Debt Deflation. Instead of banking being industrialized as Marx expected, industry is being financialized. Instead of democracy freeing economies from land rent, natural resource rent and monopoly rent, the rentiers have fought back and taken control of Western governments, legal systems and tax policy. The result is that we are seeing a lapse back to the pre-capitalist problems that Marx described in Volumes II and III of Capital and Theories of Surplus Value.
Bertell follows Marx in focusing on the production sector: hiring labor to produce products, but trying to get as much markup as possible – while underselling rivals. This is Marx’s great contribution to the analysis of capitalism and its mode of production – employing wage labor at a profit. I agree with this analysis.
However, my focus is on the causes of today’s crisis that are independent and autonomous from production: rentier claims for economic rent, for income without work – “empty” pricing without value. This focus on rent and interest is where I differ from that of Ollman, and also of course from that of Roemer. Any model of the crisis must tie together finance, real estate (and other rent-seeking) as well as industry and employment.
In retrospect, Marx was too optimistic about the future of industrial capitalism. As noted above, he viewed its historical mission as being to free society from rent and usurious interest. Today’s financial system has generated an overgrowth of credit, while high rents are pricing American labor out of world markets. Wages are stagnating, while the One Percent have monopolized the growth in wealth and income since 1980 – and are not investing in new means of production. So we still have the Volume II and III problems, not just a Volume I problem.“
I wonder whether Michael Hudson is ignoring the reach of technology and our capacity for overproduction which made this inevitable.

An easy method for changing habits?

A Stanford University psychologist’s elegant three-step method for creating new habits via Lambert Strether at Naked Capitalism. I think that I already stumbled upon this in a small way and have been using Fitbit to manage my walks. More at the following which I have not read.

Autobiographical sketch from Michael Hudson

Michael Hudson: Life and Thought – An Autobiography it also provides a guide to some of his books, in particular the five volume series edited by him in collaboration with various others. I do not know Economics but generally what Michael Hudson said or says seems sensible to me. About a month ago, I borrowed from the library his five volume series of seminars and started browsing again. This will provide a guide to me while revisiting various books of his. A similar sketch from three years ago. Bibliography and his 

Lougi Zingales on Economics and feminism :
The Columbia Business School faculty proposed an interesting default rule to resolve these power imbalances. In case of disputes between a senior and a junior faculty, the intellectual property right of a joint project should be automatically allocated to the junior faculty, to protect the weaker contracting party. Such a rule should be adopted by all departments.”

Moving to cities

About U.S. But seems common in many other countries:
How to keep young people from fleeing small towns to big cities  "Communities also must change the way they train young people. One important thing Carr and Kefalas uncovered in their book about brain drain is that many communities have brought this problem on themselves. "Fueling the out-migration is a regional filtering system pushing some young people to stay and others to go," they write. "Teachers, parents, and other influential adults cherry-pick the young people destined to leave and ignore the ones most likely to stay or return. Civic leaders may lament the rural youth exodus and the accompanying brain drain, but they fail to see how their own actions have helped create the problem.""

Gulzar Natarajan on Indian agriculture

India’s agriculture paradox- farmers subsidising consumers? “The conventional wisdom would have it that India's agriculture and its farmers are heavily subsidised and therefore inefficient. This is clearly not borne out by data. ”

Top revenue collectors

Of the World’s top 100 economic revenue collectors, 29 are states, 71 are corporates And "There are 14 Chinese firms in the top 100, but 27 from the US".

Trump-Putin friendship

Some are optimistic about climate change

Economics How Changing My Economic Model Made Me a Climate Change Optimist:
"Two trends give reason for guarded optimism. The first is that governments have been doing many of the right things all along. Research support has gotten needed technologies invented, ever since NASA gave us photovoltaic cells. For many of these, directed support has overcome the barriers to commercialization. For a small few of these, policies in some places are moving us toward market saturation and fossil fuel prohibition. The EU has been pushing carbon neutral heating systems for buildings, and starting in 2021 this will be the standard for all new construction. ....
The second trend is an historical one. Virtually every technological transition people have studied has passed through a long preparatory phase, where new systems made barely a dent on the old, to an exponential growth phase that became self-reinforcing. I think renewable energy is turning this corner."

A Telugu song which travelled around

This is about the song.Manasaina cheli pilupu from jayamsimha 1955. M.L.Narasimham in his review of the film says "T.V. Raju’s music largely contributed to the movie’s success. He was assisted by the talented Sathyam. ‘Jaya Jaya Sri Rama Raghuvara’ (Ghantasala), ‘Madiloni Madhurabhavam,’ (Ghantasala & Rao Balasaraswati) and P. Susheela’s classical rendition ‘Nadireyi Gadichene cheliya…’ became popular. Some of the hit numbers drew inspiration from Hindi songs. The duet ‘Ee naati ee haayi…’ rendered by Ghantasala and P. Leela was taken from Ghulam Mohammed’s composition, ‘Jindagi dene vale sun…’ (‘Dil- E- Naadan’) and Rao Balasaraswati, A.P. Komala’s rendition, ‘Manasaina cheli pilupu…’ adapted from Shyamsundar’s composition, ‘chori chori aagse dilme…’ ( ‘Dholak’) are examples." AK in a post in Songs of Yore says in comment 113 
"I heard the songs again. Mansaina cheli pilupu uses the interlude music of Chori chori aag si dil mein lagakar chal diye. But the tune of the song is quite different which has been copied by Madan Mahan in Mera chhota sa dekho ye sansar hai and by Ramesh Naidu in Man soona tere bin haaye re, the links of the two Hindi songs have been given by KS Bhatiaji @101."

There are also Simhala versions like Mata aloke , this one by Jikki.

Village Reconstruction Organization  
"The Belgian Jesuit Michael A. Windey had served at St. Xavier's College, Ranchi, as a professor and as founding director of the Xavier Institute of Social Service.[4][5] A typhoon on the east coast of India in 1969 with floods that submerged Guntur drew him to Andhra Pradesh, ending his career as a professor as he undertook the task of reconstructing villages.[6] 
The organization assists with the construction of villages as well as facilities within the villages: schools and skills training centers, health clinics,[9] childcare and community centres,[21] and homes for children and homes for the elderly,[22] especially among the dalits.[23] Jesuit novices help with programs such as Bala Mela, construction works in villages, laying of roads, and archeological survey.[24]"

Dan Wang on how technology grows

 Long read with interesting points: How Technology Grows (a restatement of definite optimism) via Tyler Cowen.
"The goal of both pieces is to broaden the terms in which we discuss “technology.” Technology should be understood in three distinct forms: as processes embedded into tools (like pots, pans, and stoves); explicit instructions (like recipes); and as process knowledge, or what we can also refer to as tacit knowledge, know-how, and technical experience. Process knowledge is the kind of knowledge that’s hard to write down as an instruction. You can give someone a well-equipped kitchen and an extraordinarily detailed recipe, but unless he already has some cooking experience, we shouldn’t expect him to prepare a great dish."

"What happens when we stop the flow of knowledge up the stack? I think that the weakness of the US industrial robotics sector is instructive. The US has little position in making high-end precision manufacturing equipment. When it comes to factory automation systems, machine tools, robot arms, and other types of production machinery, the most advanced suppliers are in Japan, Germany, and Switzerland. I think the reason that the US has little position can be tied directly to the departure of firms from so many segments of manufacturing. How do engineers work on the design of automation systems if they don’t have exposure to industrial processes?"

"My favorite genre of the Bloomberg column has become Noah Smith dunking on the United Kingdom. Services make up about 80% of the British economy, and that has brought along a host of problems. These include low levels of productivity growth over the last two decades, extraordinary vulnerability to the financial crisis, and low levels of R&D spending by its biggest companies. Matt Klein has put forward a fun claim: “Take out Greater London—the prosperity of which depends to an uncomfortable degree on a willingness to provide services to oligarchs from the Middle East and the former Soviet Union—and the UK is one of the poorest countries in Western Europe.”"

One excerpt "I think Trump may be one of those ļ¬gures in history who appears from time to time to mark the end of an era and to force it to give up its old pretences.”

About Vitamin D deficiency

i do not understand this well. From what I can gather, higher doses are needed than those recommended by US. Generally many other countries follow US but Finland seemed to have bucked the trend.
US admits math mistake was made in 2010 in estimating Vitamin D, but will not change recommendations – Nov 2017
Improved health due to Vitamine D fortification in Finland
I saw the general idea in this article but did not understand it well. Towards the end, the previous article links to The big Vitamin D mistake whose introduction is clearer.
