Extreme Intelligence On The Bellshaped Curve
The bell-shaped curve (normal distribution) represents how intelligence (IQ) is distributed in the population. Most people cluster around the average IQ (~100), while fewer people fall at the extremes—very low or very high intelligence.
Types of Extreme Intelligence on the Bell Curve -
1. Intellectual Disability (Lower Extreme)
- IQ below 70 (approximately 2–3% of the population).
- Categories:
– Mild (IQ 50–70): Can achieve basic academic and social skills with support.
– Moderate (IQ 35–50): Limited academic skills, needs structured support.
– Severe (IQ 20–35): Requires assistance in daily living.
– Profound (IQ below 20): Dependent on caregivers for most functions.
2. Giftedness (Upper Extreme)
- IQ above 130 (approximately 2–3% of the population).
- Categories:
– Moderately gifted (IQ 130–145): High academic and creative potential.
– Highly gifted (IQ 145–160): Exceptional problem-solving and originality.
– Profoundly gifted (IQ above 160): Rare individuals with extraordinary intellectual ability (e.g., child prodigies, polymaths).
