YOUR PERSONALITY AND NOT iq, IS KEY TO SUCCESS.

How much is a child's future success determined by innate intelligence? Economist James Heckman says it's not what people think. He likes to ask educated non-scientists - especially politicians and policy makers - how much of the difference between people's incomes can be tied to IQ. Most guess around 25%, even 50%, he says. But the data suggest a much smaller influence: about 1 or 2%. So if IQ is only a minor factor in success, what is it that separates the low-earners from the high ones?
Science doesn't have a clear answer, although luck certainly plays a role. But another key factor is personality, according to a paper Heckman co-authored in the 'Proceedings of the National Academy of Sciences' in July 2017. He found financial success was correlated with conscientiousness, a personality trait marked by diligence, perseverance and self-discipline. To reach that conclusion, he and colleagues examined four different data sets, which, between them, included IQ scores, standardised test results, grades and personality assessments for thousands of people in the United Kingdom, the United States of America and the Netherlands. Some of the data sets followed people over decades, tracking not just income but criminal records, Body Mass Index and self-reported life satisfaction.
The study found that grades and achievement-test results were markedly better predictors of adult success than raw IQ scores. That might seem surprising - after all, don't they all measure the same thing? Not quiet.Grades reflect not just intelligence but also what Heckman calls "non-cognitive skills", such as perseverance, good study habits and the ability to collaborate - in other words, conscientiousness. To a lesser extent, the same is true of test scores. Personality counts. 
Heckma, who shared a Nobel Prize in 2000, believes success hinges not just on innate ability but on skills that can be taught. Openness - a broad trait that includes curiosity - is also connected to test scores and grades. IQ still matters, of course. Someone with an IQ of 70 isn't going to be able to be able to do things that are easy for a person with an IQ of 190. But Heckman says many people fail to break into the job market because they lack certain skills - they don't understand how to behave in interviews. Or on the job, they make it obvious they will do no more than the minimum.

VIEWS OF MANU AND KAUTILYA ON THE ADMINISTRATION OF JUSTICE.

The state performed its duty of protection of society and the individual through coercive enforcement of the standards of justice based on the concept of ' Dharma '. From the Vedic period onward, the perennial attitude of Indian culture had been justice and righteousness. Justice, in the Indian context, was a human expression of a wider universal principle of nature and if men were entirely true to nature, their actions would be spontaneously just. Men experienced Justice, in the sense of a distributive equity, as moral justice, social justice, and legal justice. Each of these forms of justice was viewed as a particularisation of the general principle of the universe seen as a total organism. Impartial administration of justice was always regarded as one of the main duties of the King and he was considered to be the fountain of justice. The ethical code of society and its cultural standards were inter-related. The cultural maturity and social amicability and even their det...

ARCHAEOLOGISTS DISCOVER TOMBS IN EGYPT DATING BACK 2,000 YEARS.

Egypt's antiquities ministry said on 14th August, 2017 (Tuesday) that archaeologists have discovered three tombs dating more than 2,000 years, from the Ptolemaic Period. The discovery was made in the Nile valley province of Minya south of Cairo, in an area known as al-kamin al-Sahrawi. The unearthed sarcophagi and clay fragments suggest that the area was a large necropolis from sometime between the 27th Dynasty and the Greco-Roman period. ----------------------------------------------------------------

ANCIENT INDIA'S LINKS TO TODAY.

You may not have heard of Shu-ilishu but he is a man of great significance. He reaches out to us from almost 4,300 years ago, through a small Akkadian cylinder seal now housed at the Louvre Museum in Paris. On the seal, you will find an image of him talking to two men. The inscription describes Shu-ilishu as the interpreter of the Meluhhan language. 'Meluha' was, in all probability, the term used by ancient Mesopotamians for the Indus Valley region, and the presence of an oficial 'interpreter' there indicates just how important the steady flow of good from the Indian sub-continent was.  Precious and vibrant lapis lazuli stones, carnelian beads, wood and even dogs would go across via old trade routes and ports like Lothal (in modern-day Gujarat) to Akkad, capital of the Akkadian Empire (03rd millennium BCE) and now in modern-day Iraq. There are also references to a settlement of Meluhhans in the city of Guabba in Sumer, in Mesopotamia.  The story of Shi-ilishu and ...
