EFL/ESL Reading - Intelligence

How much does IQ contribute to a person's intelligence and how much is influenced by genes and environment? These questions have been dogging scientists for years and this has given rise to many different ways of investigating intelligence. Here are a few of the more novel studies:


In 2010 an Israeli study was carried out involving 20,000 young men. Here are the results: Smokers had an IQ of 94 and non-smokers had an IQ of 101. Furthermore, the men who smoked more than a pack a day had an IQ of 90. Among siblings, the non-smoking brother was smarter.


Research into children between the ages of 4-6 suggests that taking music lessons improves their range of vocabulary. Another study revealed that 6-year-olds who took 9 months of piano lessons were smarter than kids who took none at all. Although it must be said that better educated children are more likely to take music lessons.

Position in the family

In 2007 a study was carried out that answered some questions that families had been wondering about for a long time. It seems that the eldest sibling in the family had a slight edge, an average of about 3 points. The explanation the scientists offer is that at some point they were the only child and benefited from 100% of their parents' attention.

A healthy weight

In 2006 a French study used 2200 adults over a 5 year period to test cognitive ability. The results were as follows: People with a Body Mass Index of 20 could recall 56% of the words in a vocabulary test, while adults with a BMI of 30 could remember 44% (BMI – the optimal BMI is between 18 and 25) . Even 5 years later, when the subjects were retested, those with a higher BMI continued to have a lower recall rate.


A study in 2014 looked at 600 college students who identified themselves either as a 'dog person' or a 'cat person'. While dog lovers were more likely to be outgoing, it seems the cat people were more open-minded and non-conformists. They also performed better at the intelligence tests. The results suggested that cat people are more introverted and sensitive and they would rather stay at home, say reading a book, than go out walking a dog.

Other studies claim that those who were breast-fed, tall people, left-handed people and hairy men are more gifted and as a result, successful.
