Genius is too elusive, too subjective, too wedded to the verdict of history to be easily identified. And it requires the ultimate expression of too many traits to be simplified into the highest point on one human scale. Instead we can try to understand it by unraveling the complex and tangled qualities—intelligence, creativity, perseverance, and simple good fortune, to name a few—that entwine to create a person capable of changing the world.

Autism As a Disorder of High Intelligence PDF Versão para impressão Enviar por E-mail

How can this paradox of low IQ, but positive genetic correlations of autism risk with intelligence, be resolved? None of the papers on genetic correlations of autism with intelligence discuss possible explanations, or ways to investigate the conundrum further. I have proposed here the hypothesis that autism involves high but imbalanced intelligence, such that some or many genetically-based components of intelligence are enhanced, but imbalance across components increases risk and patterns of expression for autistic phenotypes, and for diagnoses. By this hypothesis, higher intelligence may co-occur with higher risk for imbalance and cognitive and affective consequences from it, given that the components of cognitive ability are expected to interact strongly and may do so to a greater degree at the higher end of ability. The “high intelligence imbalance” hypothesis is useful because it makes clear predictions, and thus directs attention toward specific forms of existing data and new, informative future data to collect.

Wouldn't it be better to just act as if we are equal, evidence to the contrary notwithstanding? That way, no people will be discouraged from chasing their dreams — competing in the Olympics or performing at Carnegie Hall or winning a Nobel Prize.

The answer is no, for two reasons.

Human intelligence is being defined and measured for the first time ever, by researchers at the University of Warwick. Led by Professor Jianfeng Feng in the Department of Computer Science, studies at Warwick and in China have been recently undertaken to quantify the brain's dynamic functions, and identify how different parts of the brain interact with each other at different times -- namely, to discover how intellect works.

Through the past few decades of summer blockbuster movies and Silicon Valley products, artificial intelligence (AI) has become increasingly familiar and sexy, and imbued with a perversely dystopian allure. What’s talked about less, and has also been dwarfed in attention and resources, is human intelligence (HI). In its varied forms — from the mysterious brains of octopuses and the swarm-minds of ants to Go-playing deep learning machines and driverless-car autopilots — intelligence is the most powerful and precious resource in existence.

IQdb: an intelligence quotient score-associated gene resource for human intelligence PDF Versão para impressão Enviar por E-mail

Intelligence quotient (IQ) is the most widely used phenotype to characterize human cognitive abilities. Recent advances in studies on human intelligence have identified many new susceptibility genes. However, the genetic mechanisms involved in IQ score and the relationship between IQ score and the risk of mental disorders have won little attention. To address the genetic complexity of IQ score, we have developed IQdb, a publicly available database for exploring IQ-associated human genes. In total, we collected 158 experimental verified genes from literature as a core dataset in IQdb. In addition, 46 genomic regions related to IQ score have been curated from literature. Based on the core dataset and 46 confirmed linked genomic regions, more than 6932 potential IQ-related genes are expanded using data of protein–protein interactions.

Life Extension Factor Klotho Enhances Cognition PDF Versão para impressão Enviar por E-mail

In a paper just published in Cell Reports, Dena Dubal, Lennart Mucke, and their colleagues provide strong evidence that klotho enhances cognitive function, separate from its effects on aging. They started by looking at humans carrying an interesting variant of the KLOTHO gene. The variant was known to be associated with increased longevity, and the authors show that it leads to higher levels of klotho in the blood. Moreover, they show that carriers of the variant exhibit enhanced cognition, scoring higher on multiple tests of various aspects of cognitive function. The results suggest that systemic increases in klotho levels can improve cognitive function. So the authors took the experiments into mice. They found that elevation of klotho levels leads to improved learning and memory, seen in various tasks and shown not to be age-dependent. They went on to describe specific effects on synaptic function and plasticity that may account for the cognitive changes.

The relationship between intelligence and creativity PDF Versão para impressão Enviar por E-mail

The relationship between intelligence and creativity has been subject to empirical research for decades. Nevertheless, there is yet no consensus on how these constructs are related. One of the most prominent notions concerning the interplay between intelligence and creativity is the threshold hypothesis, which assumes that above-average intelligence represents a necessary condition for high-level creativity. While earlier research mostly supported the threshold hypothesis, it has come under fire in recent investigations.
