Marrying a person or befriending people cleverer than you can help boost your intelligence quotient (IQ).
It has long been thought that intelligence remains static when a person turns 18. But, a New Zealand-based psychologist says that IQ can grow all through adulthood, especially for people with stimulating lifestyles.
‘Find a job that carries out intellectual challenges on employees to boost your IQ level over the years.’
Researcher James Flynn, a professor at Otago University, says, families, where people challenge, talk, discuss, joke and share cultural pastimes can improve the IQ of members by several points.
Likewise, workplaces that carry out intellectual challenges on employees can raise their individual IQ over the years, says Flynn.
Flynn says in his new book called "Does Your Family Make You Smarter?" that intelligence is not fixed. The brain is like a muscle - the more you flex it, the stronger it gets. It means that the intelligence can be upgraded as you progress through life.
The best way to boost the IQ is to marry a person who is more intelligent than you are, finding an intellectually challenging job or hanging out with clever friends could upgrade your intelligence level.
The increase in intelligence is linked to a combination of factors, including better education, better nutrition and the world that continues to grow into something more complex and more intellectually challenging.
