The question is more complicated than it seems. Even though it is easy to agree to that some people are more competent in their social behavior than others, it has proven to be very difficult to define what we mean when we talk about social skills (or "social intelligence", "social competence"). Is it the ability to manage social relationships, does it ...

There is little neurological evidence that finds a difference between men and women. However there are psychological studies that do find a small difference in mental strengths. This interesting TED talk debunking psychological myths by a lecturer from the University of Liverpool discusses the psychological differences between men and women. Males and ...

Firmin et al. (2008) tested the validity of a handful of online IQ tests by having college students complete IQ tests at three different websites and also complete a validated lab measure, the Reynolds Intellectual Assessment Scales (RIAS). They found that there were moderate correlations ($r$ values were around 0.4 to 0.5) between some of the online tests ...

Because it has been a few years since Jeromy's original answer, and because I just read a very apt article, I will venture an update on the state of the field with respect to the BPI's validity. Overall, despite more research into brain training and Lumosity, there is little to no peer-reviewed evidence supporting the Lumosity BPI's validity, nor evidence ...

A systematic meta-analysis of the relationship between IQ and obesity (Yu, Han, Cao and Guo, 2010) suggested that lower IQ in childhood was associated with later adult obesity via educational level. No evidence of a relationship between IQ and obesity was found for adults. Our study and review of the literature overall suggests that there are inverse ...

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 ...

There are many definitions of intelligence. I find the one given by David Wechsler (1944) useful in the context of this question: The ... capacity of the individual ... to deal effectively with his environment Finding a solution quickly is sometimes necessary if you want to deal with your environment effectively. Not all problems will wait for you to ...

The question you have asked is not a new one. In fact, from the times of classical antiquity, Plato considered artistic creativity as a result of god-given madness. When it comes to popular figures in the arts and sciences, however, it is important to note that the illness is not restricted to them. Lord Byron and Beethoven are said to be manic-depressive, ...

I spent some time searching various databases with a variety of different keywords related to breathing techniques and mental outcomes. I only found a couple of studies that have looked at certain Yoga deep breathing techniques and their effects on cognitive tests measuring attention/concentration (Shirley Telles et al. 2007, 2013). Some of these specific ...

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 ...

NB: my apologies, not enough rep points to post additional links. this is far too nebulous a statement, and if it were true, would most likely be based on non-experimental data. one example that immediately comes to mind is case studies looking at the effects of social deprivation amongst children in romanian orphanages. there are also a lot of different ...

One meta-analysis of gender differences in cognitive abilities (verbal ability, quantitative ability, and visual–spatial ability): Results indicate that gender differences in all of these abilities were small: For verbal ability, the median ω–2 was .01 and the median d was .24; for quantitative ability, the median values of ω–2 and d were .01 and ...

General points about practice effects Intelligence tests differ in how much they are subject to practice effects. Practice effects can also be distinguished: Time between taking the test: The shorter the timeframe the more likely you will see practice related improvement. General practice on similar tests and similar items versus practice on the same set ...

Critical thinking is an ill-defined concept in the cognitive sciences, so this question most likely has as many answers as there are measures of IQ and critical thinking. An accessible introduction to the literature is available here, with the general cognitive conception of critical thinking given as follows: ... the mental activities that are typically ...

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 ...

There is some evidence of a moderate correlation between response times (on very simple tasks) and intelligence constructs like IQ. Here are two relevant papers and their abstracts: Deary, Der, & Ford (2001) The association between reaction times and psychometric intelligence test scores is a major plank of the information-processing approach to ...

The Torrance Test of Creative Thinking is a good place to start. It scores for fluency (number of responses) as well as originality (statistical rarity of responses) and elaboration (level of detail) on a variety of different tasks. The validity of the TTCT has been examined with several long-term studies, so there is a fair amount of data on its ...

I think what happens is that researchers often don't report on - or at least don't highlight - uninteresting results, partly because of the difficulty getting uninteresting results published. So given that gender differences in IQ in general are eliminated for validity, a lack of gender differences in IQ amongst a seemingly arbitrary sub-population such as ...

Obsessions are defined as intrusive and recurring thoughts that an individual finds disturbing or uncontrollable, and are not a good thing. There is a lay use of the word which means something like "a very strong interest," but it is just that: a perfectly normal if very intense interest, usually with no basis in abnormal psychology.

Our university has a public grade distribution database, so I did a really quick analysis on some historical data to see if there was any support for this idea. To my surprise, it appears that there might be. But, my analysis is very limited. I downloaded the grade distributions for all intro psychology and intro computer science classes from 2010-2014. ...

Just did some more reading, going to answer my own question: Fluid intelligence (Gf) refers to mental operations that an individual uses when faced with a relatively novel task that cannot be performed automatically. Inductive and deductive reasoning are generally thought to be the hallmark narrow-ability indicators of Gf. Examples of Gf abilities are: ...

I have to disagree with Arnon a bit and want to expand on some of his points. The following is not meant as an answer to the question but just an extended comment to Arnon's answer. General intelligence vs multiple intelligences There are theories of intelligence that posit a general intelligence which determins performance in all areas. According to these ...

Intelligence refers to a general cognitive capacity, it does not refer to knowledge in specific fields of study. This means that yes, it is possible to have high intelligence but have low knowledge / performance in a specific academic area. Having said that, IQ tests are validated against academic performance - that is to say, they are adjusted so as to ...

Although the idea that IQ only enables creativity "up to IQ 120" is widespread (and repeated in pop-psych books such as those of Gladwell etc.), large scale studies of giftedness reliably find that the IQ and creativity are associated even at the very highest-extremes of ability. IQ is linearly related to creative achievement across the range (Wai et al., ...

Why would I be asked to count backwards by 3, from 100 in a psychological test? This is to test your cognitive reasoning abilities, particularly your ability to concentrate and recall serial information. Similar tests are administered to injured sports players to ensure that they do not have a concussion. 1 What's a baker's dozen? What do you think ...

Sounds to me like someone is making a logical fallacy here, though the origin of this fallacy isn't clear to me. We cannot go from 'poor academic performance', to 'not amounting to anything', to 'having a low IQ'. These are not relationships of cause and effect. The motivation to do something ('amount to something', if you will) is driven primarily by the ...

To add to the existing answers (of which @what's gets special mention), an issue I don't think has really been addressed is the statistical reason for it being so difficult to measure extremely high IQs. By design, IQ is scaled so that it's normally distributed, with a mean of 100, and a standard deviation (SD) of 15. A well known feature of the normal ...

An otherwise 'brilliant' person can be slow at solving certain problems, yes. And no, cognitive performance is not the same thing as running a marathon. A marathon measures your ability to reach a certain point in a certain amount of time. An intelligence test (or any academic test, for that matter) assesses to make sure that you have learned the material ...

Does sleep deprivation cause mood swings? Few studies have focused on mood changes in healthy subjects following sleep deprivation. It seems that there is evidence for sleep deprivation causing mood changes on the subsequent day, but there is no evidence for or against it causing mood swings. Hart et al. (1987) found significantly higher self-reported ...

There are several ways in which this apparent paradox can be resolved. As a starting point, it is important to consider how heritability is defined and assessed (also see this earlier answer). As you point out, heritability estimates originate from comparisons between people who differ in their genetic similarity (e.g., monozygotic vs. dizygotic twins). The ...
