Genetics as an intelligence determiner According to many recent studies, genetics plays a bigger role in making someone smart or not than what was initially expected or hoped for. Several studies with twins2 and studies with fraternal siblings have identified intelligence as one of the highest heritable traits.
Scientists don't know exactly what causes someone to be a genius. There is probably a genetic component to your level of intelligence. Certain types of genes influence how much intellectual power you have. Your child's genetic influences affect their motivation, confidence, and other traits.
Intelligence is also strongly influenced by the environment. During a child's development, factors that contribute to intelligence include their home environment and parenting, education and availability of learning resources, and healthcare and nutrition.
The Dunning-Kruger effect is a type of cognitive bias in which people believe they are smarter and more capable than they are.
Science supports laziness
The data found that those with a high IQ got bored less easily, leading them to be less active and spend more time engaged in thought.
Faces that are perceived as highly intelligent are rather prolonged with a broader distance between the eyes, a larger nose, a slight upturn to the corners of the mouth, and a sharper, pointing, less rounded chin.
Some psychologists believe that the ability to listen to another person, to empathize with, and to understand their point of view is one of the highest forms of intelligent behavior.
Intelligence depends partly on environmental factors but genes have an influence. Research on twins has suggested that 50-80% of the variation in general intelligence between people could be down to genes but the gene variants responsible for intelligence haven't yet been identified.
Summary. Geniuses are both born and made. While genetics can explain up to 75% of variations in IQ levels, factors like socioeconomic status and home environment decide whether a person achieves their full genetic IQ potential.
Spatial intelligence or picture smart is a quality that is perhaps the rarest of all the nine Howard Gardner categorized. Human life is big, human intelligence is even bigger. It is impossible to categorize human intelligence.
They don't make assumptions and set out to form their own opinions. They follow the trail of the seemingly random questions that pop into their mind, as they know that it doesn't always directly lead to answers but that the question alone might spark a brilliant train of thought.
Early twin studies of adult individuals have found a heritability of IQ between 57% and 73%, with some recent studies showing heritability for IQ as high as 80%. IQ goes from being weakly correlated with genetics for children, to being strongly correlated with genetics for late teens and adults.
Is good memory an indicator of intelligence? Essentially, yes, but not in the way you may think. Short-term memory storage is linked to greater signs of intelligence as measured in IQ tests. But having perfect recall isn't necessarily correlated with high intelligence.
Does an individual's IQ change with age? An individual's IQ does not change with age. In other words: if you did an IQ test now and then another one in 10 years' time, your IQ score will probably be very similar. This is because IQ is always measured relative to other people your age.
Souza's study demonstrated that an individual with an IQ of 126 or higher can often learn in one hour what it would take someone with an IQ in the standard range 4-5 hours to learn. This means that gifted people can truly read and understand faster than an average person.
Let us go back to the four core features of behaviour that characterise intelligence, namely generality, flexibility, goal-directedness and adaptivity.
Figure 7.12 Sternberg's theory identifies three types of intelligence: practical, creative, and analytical.
Psychology Today reported that intelligent people are likely to be nocturnal beings, with those with a higher IQ going bed later on both weeknights and weekends.
The faces that look high IQ vs low IQ
“In both sexes, a narrower face with a thinner chin and a larger prolonged nose characterizes the predicted stereotype of high-intelligence, while a rather oval and broader face with a massive chin and a smallish nose characterizes the prediction of low-intelligence.”
Intelligent eyes seem to be for some reason more glossy and reflective than "average" eyes. While some people may look around by rotating their head, intelligent people tend to dart back and forth, as if they were looking between multiple objects.
