The general consensus around this question is yes, you can in fact increase your IQ. However, there are many factors to consider when assessing this statement. First, studies have shown that IQ can change drastically when people are younger. That said, an IQ test is an imperfect psychometric method for assessing a biological IQ. So, in a sense people can train themselves in certain ways to improve neural efficiency or practice methods of thinking that will help you perform better on an IQ test. Several professionals debated this very topic several years ago on livescience.com if you’d like to read some further opinions on the subject.

IQ measures various areas of intelligence such as memory, spatial recognition and analytical thinking. It does not measure any specific area of knowledge, instead it measures your ability to learn.

IQ stands for Intelligent Quotient. It is the measure of a person’s intelligence.

Generally, IQ tests fall between a 5-6 point variance when administered consistently, meaning that they are quite accurate. Of course, there are outside factors like personal stress that may impact a person’s performance, but by and large popular tests like the Wechsler tests are viewed as accurate.
