It's a psychological concept used to approximate someone's psychometric intelligence, which has been shown to be useful in predicting job Performance and various measures of academic success. The popular, but ancient, method of calculating IQ, or intelligence quotient, was to divide someone's mental age by their actual chronological age. Contemporary methods involve plotting one's relative score on a distribution score, derived from a norming group which is usually stratified by chronological age, which allows individuals of all ages to have their IQ's evaluated.

It's tended to be used as a conversational last resort, which is more typical among those with a IQ worth mentioning, or in some cases, rights to brag. Those mentioning an IQ above 140 are usually easily identified as the classical Braggart; Less then .4% of the population are able to earn an IQ this high on commonly accepted IQ tests.

Also, Communication difficulties and other academic or learning problems doesn't mean that someone MUST HAVE A low IQ, Albert Einstein being the common example. I happen to be another.
My IQ is 145, or at least that's what the graduate psychometrist told me. No really. I'm not making this up. Despite my admonition in the definition, I, this definition's writer, have an IQ above 140.

Like anyone cares though. Haha.

I'm pretty sure that's going to earn a couple of thumbsdown.

IQ = Intelligence Quotient
A measurement of a persons logical ability and ability to identify and understand logical patterns. Although much-debated these abilities correlate to a lot of common things, such as proficiency for higher education (an average PhD has an IQ of 125).

The scale was originally based on mental age divided by actual age but is nowadays based on a logarithmic curve which orders IQ by percent (about 2/3rds of the population lies between 85 and 115 and about one in 1000 has 150+). The average is 100.

The importance of IQ should however not be overstated since social skills, personality, work morale and other factors are at least as important in a working environment.
IQ is a good measurement for how much you enjoy brain-fapping.

Of no real importance to anything, except when someone is so off the mark when socialising/ courting/ drinking/ talking/ being in an interview that they quote there own!

This brings immediate clarity to the fact that they are a douchebag ass and most probably still a virgin, although not to the hand!

An acronym for Intelligence Quotient, a quality that remains constant throughout a person's life. It is a ratio of mental age to actual age and determines the ability of an individual to succeed in and adapt to complex environments. IQ greatly influences the person's GPA, SAT scores, Education Level, Job Performance, Salary and Career Attainment.
Dumbo: Hey do you know why Bill Gates is the richest and most powerful man in the world, and why Microsoft is so successful?
