IQ is a mean of 100 and a standard deviation of 15. It is statistically possible to have a negative IQ. IQ -5 is 7 standard deviations below the mean (Z-score -7.0) and dumber than 1 in 781 billion people, or around 1000 times the world's population.
The lowest IQ score is 0/200, but nobody in recorded history has officially scored 0. Any result below 75 points is an indicator of some form of mental or cognitive impairment.
Negative intelligence is knowing what not to do. We cultivate negative intelligence when we focus on negative thoughts. Focusing on what we do badly does not help us do something well. Negative intelligence is information, not necessarily knowledge.
They can, but it's not just that. It's that IQ is a very noisy measure of all intellectual talents averaged together, and some people with unimpressive general IQs can still be extremely talented in particular fields.
You can have a high IQ, but lack education and general knowledge. You can earn a degree yet score a lower IQ. IQ tests measure your ability to reason, grasp ideas, and solve problems.
Elon Musk IQ is close to this starting point, with an estimated score of 155. The typical genius has an IQ of around 140.
In addition to slowing down physically, most people lose points on intelligence tests as they enter their golden years. Now, new research suggests the loss of certain types of cognitive skills with age may stem from problems with basic sensory tasks, such as making quick judgments based on visual information.
Abilities change, but IQ scores tend to be very stable. However the intelligence ability is changing during the life, the IQ (intelligence quotient) does not. This measure is defined to have mean of 100 in each age group. So the average IQ e.g. in the age 5 is 100, and the same in the age 50.
However, the lowest IQ score possible is zero. Can someone actually get this low of a score? In theory, yes. But no one in recorded history has officially scored zero on an IQ test, even if that result is theoretically attainable.
Spatial intelligence or picture smart is a quality that is perhaps the rarest of all the nine Howard Gardner categorized.
Stupidity – Lack of intelligence.
A Breakdown of IQ Scores

IQ compared by countries
With an average IQ of 98 points, the USA ranks 29th in this ranking. With 108 points, the inhabitants of Hong Kong reach the highest intelligence quotas worldwide. The last place, with only 56 points, is occupied by Equatorial Guinea.
Parents tend to search “What is the average IQ for a 13-year-old?” or “What is the average IQ for a 10-year-old?”. The key point to remember is that all tests are designed to get an average score of 100 for people of all ages. Current average IQ scores vary between 85 and 115 (about 68% of people).
Researchers have previously shown that a person's IQ is highly influenced by genetic factors, and have even identified certain genes that play a role. They've also shown that performance in school has genetic factors. But it's been unclear whether the same genes that influence IQ also influence grades and test scores.
The average child's IQ is not stable until around four years of age. It may be much later in children who were born early or who have significant health issues.
Alzheimer's, dementia, drugs, getting hit in the head too much (boxing, mixed martial arts, etc.) will all reduce IQ. But the easiest and most common way that IQ drops is to recognize that the brain is like a muscle. If you don't use it, it can atrophy and get weaker.
Although science is on the fence about whether you can raise your IQ or not, research does seem to suggest that it's possible to raise your intelligence through certain brain-training activities. Training your memory, executive control, and visuospatial reasoning can help to boost your intelligence levels.
According to their data, people as young as 40 have performance IQs 20% lower than 16 year olds. The data is also similar to the standardization samples of the WAIS-R, which also indicates that performance IQ drops after age 22, but that people reach their verbal IQ peak around age 30.
Your IQ test score actually reflects how well you do in various mental activities, and therefore, can be a good criterion to know if you can be successful in a specific field of study. The results from an IQ test should be analyzed carefully, but a score between 90 and 109 indicates average intelligence.
Adragon De Mello: IQ 400
