IQ scores are often misunderstood. People see a number and don't know whether it's good, bad, or what it implies for daily life. Understanding what your IQ score means requires knowing how scores are distributed, how they're interpreted, and what they predict about your life.

How IQ Scores Are Distributed

IQ scores follow a normal distribution (bell curve) with an average of 100 and a standard deviation of 15. This means:

• 68% of people score between 85 and 115

• 95% score between 70 and 130

• 99.7% score between 55 and 145

The further from 100 a score is, the rarer it becomes. An IQ of 130 is higher than about 98% of the population. An IQ of 145 is higher than 99.9%—roughly 1 in 1,000 people.

What Different IQ Ranges Mean

IQ 145+: Extremely High

This range represents the top 0.1% of the population. People with IQs this high typically:

• Excel in academic settings without much effort

• Grasp complex abstract concepts quickly

• Often qualify for high-IQ societies like Mensa (which requires top 2%) or more selective organizations

• Have access to virtually any career requiring cognitive ability

However, an extremely high IQ doesn't guarantee success or happiness. It opens doors, but walking through them requires motivation, social skills, and other qualities beyond intelligence.

IQ 130-144: Very High

About 2% of people score in this range. Characteristics include:

• Strong academic performance in most subjects

• Qualification for most gifted programs

• Ability to handle cognitively demanding careers

• Quick learning and problem-solving

People in this range often complete advanced degrees and work in professional fields requiring significant education.

IQ 120-129: High Average

This range includes roughly 7% of the population. These individuals:

• Perform well in school with reasonable effort

• Can succeed in most college programs

• Qualify for many professional careers

• Generally don't struggle with cognitive demands of daily life

The difference between someone with an IQ of 125 and someone with an IQ of 105 is noticeable in academic settings but might be less apparent in everyday interactions.

IQ 110-119: High Average

About 16% of people fall here. They:

• Handle typical school curricula without major difficulty

• Succeed in jobs requiring moderate cognitive complexity

• Generally function well across life domains

• May find very abstract or theoretical material challenging

Most people in this range complete high school successfully and can attend college if they choose.

IQ 90-109: Average

This is where half the population falls. People with average IQs:

• Represent the norm in cognitive ability

• Can learn most practical skills needed for daily life

• Succeed in jobs with moderate cognitive demands

• May struggle with highly abstract academic content

Average IQ is, by definition, typical. These individuals function normally in society and can lead successful, fulfilling lives.

IQ 80-89: Low Average

About 14% of people score in this range. They typically:

• Complete high school, often with some difficulty

• Struggle with abstract or theoretical content

• Work in jobs with less cognitive complexity

• Function independently but may face challenges in complex situations

This range is below average but not low enough to constitute a disability. People here generally manage their own lives without formal support.

IQ 70-79: Borderline

Roughly 6% of the population falls here. Individuals in this range:

• Often struggle in traditional academic settings

• May receive special education services in school

• Work in jobs with limited cognitive demands

• Usually live independently but might need occasional assistance

• Face higher risks for poverty and other negative outcomes

This is sometimes called the "borderline" range because it's near the threshold for intellectual disability but doesn't quite meet diagnostic criteria.

IQ Below 70: Significantly Below Average

About 2-3% of people score this low. An IQ below 70, combined with deficits in adaptive functioning (practical daily living skills), typically qualifies for an intellectual disability diagnosis.

People in this range usually:

• Need significant educational support

• Struggle with independent living (degree depends on how far below 70 they score)

• Require assistance with complex tasks

• Benefit from structured support services

It's important to note that IQ alone doesn't determine disability status. Adaptive functioning (the ability to handle daily life tasks) matters equally.

What IQ Predicts

IQ correlates with numerous life outcomes:

Academic performance. IQ is one of the strongest predictors of educational success. Higher IQ makes school easier and opens doors to advanced education.

Occupational outcomes. IQ predicts job performance, especially in cognitively complex positions. It also relates to occupational prestige and income.

Health and longevity. Higher IQ correlates with better physical health and longer life. The reasons aren't fully understood but likely involve better health decisions, quicker recognition of symptoms, and more effective navigation of healthcare systems.

Mental health. Generally, higher IQ is associated with better psychological wellbeing, contrary to the "tortured genius" stereotype.

Life outcomes. IQ also relates to lower divorce rates, reduced criminal behavior, and various other outcomes.

The Bottom Line

An IQ score indicates how your cognitive abilities compare to others in your age group. Higher scores predict better outcomes in many domains, but IQ isn't destiny. It's one factor among many shaping your life.

Understanding what your score means helps set realistic expectations and make informed decisions. But remember: intelligence is important, but it's not everything. Success, happiness, and a meaningful life depend on far more than a number on a test.
