The truth about intelligence is that few people know it

Intellectual games do not help people be smarter, IQ tests are not absolute assessments. These conclusions are given by Medical magazine, which may surprise you because they are different from what we used to know.

>>>Intelligence in the perspective of science

The effect of intellectual games

The incidence of Alzheimer's disease and other dementia syndromes are on the rise. Before this fact, some companies like Lumosity have introduced intellectual games models that are thought to be useful for the brain. These games are quite simple, often involving memorizing words or putting pictograms in place, thereby creating a positive effect on memory and concentration.

According to experts, although the correct solution is theoretical, there are still many misconceptions that games can improve intelligence. Intellectual game is introduced with a commitment to enhance memory, concentration and skills to solve many tasks at the same time. However, in practice, for the overall human intelligence, these games do not work.

In the study, volunteers were asked to perform one of three tasks with different difficulty levels, including remembering the group of objects while conducting another complicated task, recalling the objects in the order they were See before, or search for special objects in the group.

The results show that participants completing the initial task show signs of working memory, but the ability to solve new problems, reasoning or identification (fluid intelligence) does not change. .

The relationship between wisdom and neuropathy

John Nash, a famous American scientist, is one of the most influential economists of the 20th century with great contributions in many areas: market economy, evolutionary biology, and human intelligence. create ., but John Nash suffers from schizophrenia. Some other famous people in the world who have had mental illnesses include Abraham Lincoln, Isaac Newton or Ernest Hemingway.

Researching a gene that codes for calcium-binding proteins called NCS-1, the scientists found that this gene is also involved in the toughness of synapses. Incidentally, the study also showed that the regulatory enhancement of NCS-1 is related to schizophrenia and bipolar disorder.

This means that the greater the toughness, the more intelligent people can be, but the higher the risk of mental illness. In another study in 2005, scientists found that people with higher-performing math tests were more likely to have bipolar disorder.

The awake can be smarter

Many studies have been done and demonstrated the harmful effects of staying up late. The effects of light from computers, televisions, or simply staying up late at the biological rate warn that the body needs rest, which hinders some biological processes in the body. The risk of diabetes, cancer and reproductive problems is also higher.

However, according to the 2009 study, because the activities only take place during the day and at night is the time to sleep, people who are active at night may be smarter. In another study conducted last year, experts found that people who stayed up often had higher scores on the test of inductive reasoning. This is an indicator of general intelligence in people.

IQ testing does not fully evaluate intelligence

According to research with Canada's support in 2012, intelligence is determined by short-term memory, reasoning ability and language of each person. These factors are independent and cannot be completely determined by an IQ test.

In an interview with Scientific American, psychologist W. Joel Schneider said the effectiveness of the IQ test depends on what is tested. For study skills, IQ testing is not effective because this ability can be influenced by the opportunity, different in culture, family or personality of each person.
