The short answer: No, sex differences in professions is not a good basis for judging the intelligence of males and females. This question has already received flags to be closed. However, I think it should be left open particularly because it can be answered and I would like to address some of the assumptions and misconceptions in the question. First, I ...

Like any simple-seeming cognitive sciences question, it is important to start with a series of disclaimers. It might seem like human intelligence or intelligence more generally is an intuitive concept, but once you start to explore your intuition or look at historic definitions of intelligence, you see that intelligence is a very ill-defined and slippery ...

ISO 9241, a standard covering ergonomics of human-computer interaction, defines in its subsection 9241-110, "Dialogue Principles", that the interface in information systems should be (among other things): suitable for the task facilitate learning conform with user expectations describe its own purpose and functioning You could translate all this to: ...

Actual correlation between physical attractiveness and IQ is somewhere between insignificant and mildly positive, with a slightly higher correlation for men. The correlation between physical attractiveness and perceived intelligence is more significant. There are typically two approaches to explain this (nature vs. nurture): From an evolutionary ...

So you're basically asking what are the causes of interpersonal differences in intelligence as typically measured by standardised psychometric tests. This question forms the basis for a large proportion of the literature on intelligence. For example see a journal like Intelligence. For a review you could read Intelligence: Knowns and Unknowns A few quick ...

A lot of research seems to have been done on the challenges multilingualism poses for the human brain, but not so much on how much actually meeting those challenges improves one's overall cognitive capacity. At present the general approach seems to be summed up: "Cognitive science suggests that the brain has selective resources with limited capacity" (Emily ...

The answer is "yes." The entire field of Human Factors and Ergonomics is devoted to enhancing the experience of the human user. Cognitive engineering is the branch of human factors that focuses specifically on how people perceive and respond to system interfaces. Engineers and scientists in this field try to design components, systems, interfaces, and even ...

Assuming you're getting at a related idea to your other recent question (Does a more ergonomic and user friendly interface/device make the human brain work less?), I wouldn't worry about user friendliness causing mental atrophy by precluding the need for thought. Thought continues well beyond matters of control to matters of application and optimization. ...

Unanswered questions don't necessarily cause cognitive dissonance. Need for closure varies across individuals; some of us don't mind having some (or even many) unanswered questions much at all. One also moves forward along a path while "looping," and that path isn't necessarily infinite; in fact, it probably isn't for any mortal, practically speaking. For ...

We are driven by this need to find answer to our questions. Many questions arise from one's mind by experiencing new events or feelings, or having to sort out a cognitive dissonance. An example of this would be the need for victims to find the guilty. When we can’t immediately gratify our desire to know, we become highly motivated to reach a concrete ...

Your explanation limits your question to the present day United States. Richard Lynn (2004) indeed found that American Jews have a higher verbal intelligence than non-Jewish whites by an average of 7.5 IQ points. But since American Jews are largely descendants of European immigrants, their higher relative intelligence might be a result of so-called "eugenic ...

I hadn't heard of the Bhatia measure before. A little research (see page 42 of Sharma and Sharma) explains that it is a performance based measure of ability for children in India. In general, you should obtain the test manual to learn about the recommended scoring procedure. A quick Google suggests it might be available from here: http://www.npcindia.com/ ...

The relationships between race and IQ is a sensitive topic for many good reasons. It also raises a lot of deep questions about how to assess the role of genetics and environment. A good summary of the literature on Intelligence with a discussion of racial differences can be found in the article "Intelligence: Knowns and Unknowns" (FREE PDF). Within-group ...

Here's an interesting abstract from a relevant paper I found a while back: This paper proposes a new theoretical model of curiosity that incorporates the neuroscience of "wanting" and "liking", which are two systems hypothesised to underlie motivation and affective experience for a broad class of appetites. In developing the new model, the paper ...

I'm inclined to see it as more a matter of statistics. Since you're asking a question of rank, the possibility depends on the population. For an extreme example, if you were the last man on earth, you'd be your own super polymath by default! Given a population of $N>7\rm B$, competition is of course much fiercer. Since the chance of being #1 in any skill ...

I'm not sure the article really covers the economic aspects. Drinking is an expensive hobby, enjoyed by many in well paid jobs who are able to fund it. It's not just the social aspect it may be drinking at home but I would say this could also be impacted by the type of jobs that are better paid or require more intelligence. Many people in higher-end jobs ...

Kazimierz Dabrowski had a great theory (the Theory of Positive Disintegration) about the relationship between psychoneuroses, the most common symptoms of mental illness, and the developmental trajectories of gifted people. In brief, gifted people are more likely to live out-of-sync with their social environments (too smart, too intense, too righteous, too ...

From my modest point of view, I am guessing that curiosity is a trait that evolved with primates. Curiosity may have helped our ancestors find new sources of food, or better avoid predators by watching them and being more aware of their surroundings. And then human babies, if praised for their curiosity in their youth, grow up to love being curious. And ...
