It is the power of one's intellect, and as such is clearly a very important aspect of one's overall well-being. Psychologists have attempted to measure it for well over a century. Intelligence Quotient IQ is the score you get on an intelligence test. Today, scores are calibrated against norms of actual population scores. To understand IQ and the research involving IQ, we need to understand the basics of descriptive statistics:. The normal curve. This curve, also called the bell-shaped curve, is an idealized version of what happens in many large sets of measurements: Most measurements fall in the middle, and fewer fall at points farther away from the middle.
Here, most people score near the average , and much less people score very high or very low. The mean. The mean is just the average. The standard deviation. The standard deviation is like the average degree to which scores deviate from the mean. To understand the next discussion, we need to know about correlation. Correlation is what you are doing when you compare two sets of measurements each set is called a variable.
Of course, the taller you are, generally speaking, the more you weight. But it is obviously not a perfect co-relation, because some people are thin and some are fat. An example would be the volume of water vs the weight of water. Perfect correlation can also be An example would be the amount of ink left in your printer vs the amount of ink used up.
Some argue that IQ can be improved. In , a group of researchers re-analyzed data from an experimental program conducted in the late s.
They found that after students received training in creative problem-solving once a week for 3 years, they gained around 15 points on IQ tests, compared to their scores before the program. Emory University , Harvard Extension School , and University of Minnesota all offer courses in creative problem-solving. Or if you prefer to practice on your own, you might consider some reading on the subject. A number of studies have shown that when co-workers participate in EI-related training programs, it may help improve their:.
Reading gives you a chance to immerse yourself in the experiences of other people — whether those people really exist or are fictional characters. Studies show that reading may help improve your social thinking skills, which researchers think is important for building empathy. Researchers have found that when people practice finding relationships between ideas and objects, their scores on measures of general intelligence tend to improve.
In a small study , students who practiced activities like these had a significant jump in their scores on the Wechsler Intelligence Scale for Children. Some studies have shown that spiritual intelligence training may improve health outcomes and job satisfaction in nursing care settings.
Intelligence has many factors, some of which are connected to your ability to reason and others to your ability to feel emotion. IQ tests measure your ability to solve problems, use logic, and grasp or communicate complex ideas. EQ tests measure your ability to recognize emotion in yourself and others, and to use that awareness to guide your decisions.
Both kinds of intelligence can influence your job performance, relationships, and overall well-being. Understanding and developing both kinds of intelligence may be the key to success in many areas of your life.
Practicing certain lifestyle habits may help boost your intelligence and stimulate your brain. The idea that Bush is just one foolish smart person among many, and that intelligence is a poor predictor of "good thinking", comes from a series of recent experiments that compared the performances of people of a range of intellectual abilities on rational-thinking tasks. In a study published last year, Stanovich and Richard West of James Madison University in Harrisonburg, Virginia, found there was no correlation between intelligence and a person's ability to avoid some common traps of intuitive-thinking Journal of Personality and Social Psychology, vol 94, p On certain types of thinking tasks, such as those involving number ratios, probabilities, deductive reasoning and the use of hindsight, intelligent people do perform better, Stanovich and others have found.
This is particularly true when any intuitive pitfalls are obvious, especially if a correct answer depends on logic or abstract reasoning - abilities that IQ tests measure well.
But most researchers agree that, overall, the correlation between intelligence and successful decision-making is weak. The exception is when people are warned that they might be vulnerable to a thinking bias, in which case those with high IQs tend to do better. This, says Evans, is because while smart people don't always reason more than others, "when they do reason, they reason better".
For example, consider the following problem. Is a married person looking at an unmarried person? If asked to choose between yes, no, or cannot be determined, the vast majority of people go for the third option - incorrectly. If told to reason through all the options, though, those of high IQ are more likely to arrive at the right answer which is "yes": we don't know Anne's marital status, but either way a married person would be looking at an unmarried one.
What this means, says Stanovich, is that "intelligent people perform better only when you tell them what to do". Perkins explains this as follows: "IQ indicates a greater capacity for complex cognition for problems new to you. But what we apply that capability to is another question. Think of our minds as searchlights. IQ measures the brightness of the searchlight, but where we point it also matters. Some people don't point their searchlights at the other side of the case much, for many reasons - entrenched ideas, avoidance of what might be disturbing, simple haste.
A higher wattage searchlight in itself is no protection against such follies. A survey of members of Mensa the High IQ Society in Canada in the mids found that 44 per cent of them believed in astrology, 51 per cent believed in biorhythms and 56 per cent believed in aliens Skeptical Inquirer, vol 13, p The idea that IQ is a poor measure of rationality is not without its critics, though.
Compared with 50 Einsteins you would have a very low IQ, compared with 50 children in the second grade you would have a much higher IQ. Your IQ therefore is a score you achieve relative to a group of others. The average of that group is defined as That is why we call it a 'quotient'. And that is why IQ is not the same thing as intelligence. To find out more about IQ and intelligence, read what is IQ and what is intelligence.
