If you’re intelligent, you’re better off alone.

when smart people spend time with their friends, it makes them less happy.   Why would intelligent people not gain happiness when they’re around close family and friends?

The findings in here suggest (and it is no surprise) that those with more intelligence and the capacity to use it … are less likely to spend so much time socializing because they are focused on some other longer term objective.

“More intelligent individuals, who possess higher levels of general intelligence and thus greater ability to solve evolutionarily novel problems, may face less difficulty in comprehending and dealing with evolutionarily novel entities and situations,” Li and Kanazawa

Intelligent people see different novel evolutionary problems, and spend their time trying to solve it. They are quicker than less intelligent people to abandon pre held social structures in pursuit of their goals.

Weightlifting Sustains Intelligence

Source: The Independent (UK), Oct 2016

Regularly lifting weights could make you more intelligent, a new study of people with the early signs of dementia suggests.

A group of people aged 55 to 86 with ‘mild cognitive impairment’ – a precursor of Alzheimer’s disease – were asked to carry out a mix of weight lifting and brain training.

… the researchers said they had found a causal link between an increase in strength and better functioning of the participants’ brains.

The same team behind it published a paper in 2014 which revealed the participants’ global cognition had improved significantly after the weight training, whereas cognitive training did not do this.

Researcher Dr Yorgi Mavros, of Sydney University, said: “What we found in this follow-up study is that the improvement in cognition function was related to their muscle strength gains.

“The stronger people became, the greater the benefit for their brain.”

“The key however is to make sure you are doing it frequently, at least twice a week, and at a high intensity so that you are maximising your strength gains. This will give you the maximum benefit for your brain.”

Sex Differences in Math and Science abilities

Source: Sage, Aug 2007

Sex differences in science and math achievement and ability are smaller for the mid-range of the abilities distribution than they are for those with the highest levels of achievement and ability. Males are more variable on most measures of quantitative and visuospatial ability, which necessarily results in more males at both high- and low-ability extremes …

Males outperform females on most measures of visuospatial abilities, which have been implicated as contributing to sex differences on standardized exams in mathematics and science.

We conclude that early experience, biological factors, educational policy, and cultural context affect the number of women and men who pursue advanced study in science and math and that these effects add and interact in complex ways.

Relationship Between Creativity and Intelligence

high level of creativity is mostly paralleled with average and below-average IQ. Children with above-average IQ and high level of creativity are few in number; and those children whose IQ is very high, on the contrary, have average and low
indicators for creativity. As compared with high results for creativity

This research highlighted the fact that the  intellectual and creative abilities are opposite qualities when being manifested in higher level which is important to be
considered in the school system, employment, etc.

Imagination: the intersection of intelligence & personality

Source: International Society for Intelligence Research, Jul 2016

Imagination refers to the ability of creating mental representations of ideas that are not present at the time so is key to translating experience into conceptual knowledge. However, it is unclear if imagination is a cognitive ability or a trait disposition. As no reliable measures for imagination exist, its relationship with other cognitive and personality factors is poorly understood.  

 the findings suggest that imagination occupies a construct space that is relatively independent from cognitive ability and is more closely associated with personality, implying that imagination may be an investment trait and part of intelligence-personality interface. This notion is also supported by the preliminary results from the 3 week-long study on learning, which illustrated that imagination plays a role for the accumulation of knowledge and recall of information.

Genetics and IQ: 5 Findings

Source: Nature.com, Sep 2014

five genetic findings that are special to intelligence differences and that have important implications for its genetic architecture and for gene-hunting expeditions.

  1. The heritability of intelligence increases from about 20% in infancy to perhaps 80% in later adulthood.
  2. Intelligence captures genetic effects on diverse cognitive and learning abilities, which correlate phenotypically about 0.30 on average but correlate genetically about 0.60 or higher.
  3. Assortative mating is greater for intelligence (spouse correlations ~0.40) than for other behavioural traits such as personality and psychopathology (~0.10) or physical traits such as height and weight (~0.20). Assortative mating pumps additive genetic variance into the population every generation, contributing to the high narrow heritability (additive genetic variance) of intelligence.
  4. Unlike psychiatric disorders, intelligence is normally distributed with a positive end of exceptional performance that is a model for ‘positive genetics’.
  5. Intelligence is associated with education and social class and broadens the causal perspectives on how these three inter-correlated variables contribute to social mobility, and health, illness and mortality differences.

These five findings arose primarily from twin studies. They are being confirmed by the first new quantitative genetic technique in a century—Genome-wide Complex Trait Analysis (GCTA)—which estimates genetic influence using genome-wide genotypes in large samples of unrelated individuals. Comparing GCTA results to the results of twin studies reveals important insights into the genetic architecture of intelligence that are relevant to attempts to narrow the ‘missing heritability’ gap.

Intelligence … is also one of the most stable behavioural traits, yielding a correlation of 0.63 in a study of people tested at age 11 and then again at age 79.

for intelligence, heritability increases linearly, from (approximately) 20% in infancy to 40% in adolescence, and to 60% in adulthood. Some evidence suggests that heritability might increase to as much as 80% in later adulthood47 but then decline to about 60% after age 80.48

A meta-analysis of 11000 pairs of twins shows that the heritability of intelligence increases significantly from childhood (age 9) to adolescence (age 12) and to young adulthood (age 17).
