Recommended: What is intelligence

One of the most common definitions of intelligence is one’s ability to learn, and apply their knowledge (Howard Gardner's Multiple Intelligences). Humans use their brains and intelligence every day, and the human ability to think and create is what allows us to be the dominant species on Earth. However, there has always been a gap of intelligence levels within our species. There are geniuses, and they can solve complex math equations without hesitation. On the other hand, we have a great percentage of people who have learning disabilities, like mental retardation. Scientists have found that there are many factors that influence an individual's intelligence, both positively, and negatively. Many links have been made between intelligence and genetics and biology, but, many scientists also have found the environment in which someone has been raised in also plays a significant role in intelligence. In the 21st century, what causes high or low intelligence still hasn't been completely determined, and scientists and researchers are debating many theories and ideas.

Your DNA consists of hundreds and thousands of gene sequences that make you, you. Your parents contributed to your genetic makeup, therefore half your genes are from your mom, and the other half your dad. Many scientists and researchers have determined that about 50% of intelligence is heritable (Causes of Intelligence). The genes you inherited from your parents give directions on how you are built. Thus, brain structure can differ depending on one's genes.

Your genes determine how your nerves are encased in myelin. Myelin is a fatty insulation in the brain used to transmit nerve signals (More Evidence that Intelligence). The thicker the myelin, the faster your brain funct...

  • Free Nature vs. Nurture Essay

    484 Words  | 1 Pages

    Today, realising that genes and environment cooperate and interact synergistically, traditional dichotomy of nature vs. nurture is commonly seen as a false dichotomy. Especially operant conditioning, i.e. the learning of the consequences of one's own behavior can lead to positive feedback loops between genetic predispositions and behavioral consequences that render the question as to cause and effect nonsensical. Positive feedback has the inherent tendency to exponentially amplify any initial small differences. For example, an at birth negligible difference between two brothers in a gene affecting IQ to a small percentage, may lead to one discovering a book the will spark his interest in reading, while the other never gets to see that book. One becomes an avid reader who loves intellectual challenges while the other never finds a real interest in books, but hangs out with his friends more often. Eventually, the reading brother may end up with highly different IQ scores in standardized tests, simply because the book loving brother has had more opportunities to train his brain. Had both brother received identical environmental input, their IQ scores would hardly differ.

    “The term “nature versus nurture” is used to refer to a long-running scientific debate. The source of debate is the question of which has a greater influence on development: someone's innate characteristics provided by genetics, or someone's environment. In fact, the nature versus nurture debate has been largely termed obsolete by many researchers, because both innate characteristics and environment play a huge role in development, and they often intersect”.

  • Argumentative Essay On Intelligence

    1196 Words  | 3 Pages

    Intelligence is a function of how well the brain works, and it's well established that our brains are designed by genes so it's not entirely surprising that some deem this as proof that our genes play a part in deciding a person’s intelligence. However, this is not a widely accepted fact and many scholars would argue intelligence is indeed not fixed by ones genes but instead manipulated by other factors.

    Most researchers believe that we are born with a certain intelligence or potential intelligence. They also believe that the intelligence we are born with is difficult to change. Psychologists use short-answer tests to assess one’s intelligence (Gardner papers). It was believed that intelligence was a single inherited thing. Human beings start out initially as a blank slate and could be trained to learn anything, provided that it was presented in an appropriate way (Multiple Intelligences and Education). Currently an “increasing number of researchers believe the opposite. Gardner defined intelligence as: “the ability to create an effective product or offer a service that is valued in culture; a set ...

  • The Measurement of Intelligence through IQ Tests

    Can intelligence be measured? Does an IQ test actually measure a person’s intelligence? Does a high score indicate a genius? Does a low score indicate stupidity or merely ignorance? These questions have been asked over and over again by psychiatrists and scientists alike, but to date there are no clear answers. These questions cannot be answered without first defining what is meant by the term intelligence. Once intelligence has been defined then it should be easy to answer these questions; however, multiple definitions of the word tend to lead to further confusion.

  • Intelligence: Nature or Nurture?

    1352 Words  | 3 Pages

    Intelligence by definition is “the ability to acquire and apply knowledge and skills” (Oxford Dictionary, 2014). However, many psychologists argue that there is no standard definition of ‘intelligence’, and there have been many different theories over time as psychologists try to find better ways to define this concept (Boundless 2013). While some believe in a single, general intelligence, others believe that intelligence involves multiple abilities and skills. Another largely debated concept is whether intelligence is genetically determined and fixed, or whether is it open to change, through learning and environmental influence. This is commonly known as the nature vs. nurture debate.

  • Behavioral Genetic Determinism: Do Genes Equal Behavior?

    2513 Words  | 6 Pages

    Human behavior is a loosely defined foundation for individuality, generally considered to be influenced and developed by the environment. However, recent molecular studies have exposed genetic factors that suggest a more biological origin for behavior. Gene segments in the genome of humans and other animals have been identified and associated with particular behavioral traits. Is it possible that the presence or absence of even a single gene may predispose one to alcoholism, increased irritability, or enhanced intelligence? Clearly exploration of the nature versus nurture argument with regard to genetic predisposition has social, political, and legal significance.

  • Intelligence: Nature and Nurture

    903 Words  | 2 Pages

    The ongoing debate on whether nature or nurture is responsible for intelligence seems to be a never-ending argument. There will probably be no definite answer to this argument any time soon, but answers such as Dr. Bigot's prove how intolerant of other opinions people can be. To say intelligence is entirely based on genetics, or one's environment, for that matter, is utterly extremist. An interaction of both nature and nurture is responsible for intelligence.

    Height, hair color, eye color and sex are just a few examples of ways our DNA has shaped us. But could it be possible that our DNA also effects the way we behave in society. It is possible that genetics effect us is more ways that we may have imagined. Dr. Peter B. Neubaur believes that shyness, eating disorders, obsessive behavior and psychological illness can all be traced back to our genetics. Sexual orientation is also believed to be derived from genes in our body which determine what sexual preference we prefer. Violence and other types of crimes can be linked back throughout a person’s lineage to witness that other family members have been committed similar crimes without ever meeting one and other.

  • The Importance Of Intelligence In Education

    1111 Words  | 3 Pages

    The Oxford Dictionary defines intelligence as “the ability acquire and apply knowledge and skills.” Many people are born naturally intelligent, able to grasp and understand concepts easily, with little work. In children, it is easy to separate those born with higher intellectual ability from the rest, because they easily excel in learning. This skill is often lost by those born with it, and through a great deal of work others attain it. In order for an individual to have true intelligence into her adult years, she must foster what gifts she is given, and strive to better her self academically. Even as early as elementary school, many who are born with natural talent begin to fall behind intellectually. These students are often not
