What is Intelligence?
Core Capacities
Intelligence is defined by a diverse set of capacities, including abstraction, logic, understanding, self-awareness, learning, emotional knowledge, reasoning, planning, creativity, critical thinking, and problem-solving. It represents the ability to perceive or infer information and retain it as knowledge for application in adaptive behaviors within various environments.
Historical Context
The term "intelligence" gained prominence in the early 20th century. While a universal definition remains elusive, psychologists generally agree that intelligence encompasses multiple domains and competencies. Its study spans various disciplines, examining its presence not only in humans but also in non-human animals and, controversially, in plants.
Etymology
Latin Roots and Philosophical Shifts
The word "intelligence" originates from the Latin nouns intelligentia and intellectus, derived from the verb intelligere, meaning "to comprehend or perceive." During the Middle Ages, intellectus became a key term in scholastic philosophy, translating the Greek term nous and linking to metaphysical theories. However, early modern philosophers like Bacon, Hobbes, Locke, and Hume favored "understanding," often viewing the medieval concept of "intellectus" as philosophically problematic. The term "intelligence" later found renewed prominence in contemporary psychology.
Defining Intelligence
A Consensus in Progress
Defining intelligence is a subject of ongoing debate among scholars, who differ on its constituent abilities and quantifiability. A 1995 report by the American Psychological Association acknowledged that while individual differences in intellectual performance are significant, no single definition commands universal assent. It highlighted the complexity of phenomena like understanding complex ideas, adapting to environments, learning from experience, and reasoning.
Perspectives from Leading Researchers
Various psychologists and learning researchers have offered definitions, emphasizing different facets of intelligence:
Human Intelligence
Cognitive Prowess
Human intelligence is characterized by complex cognitive feats, motivation, and self-awareness. It empowers individuals to learn, form concepts, understand, reason, recognize patterns, innovate, plan, solve problems, and communicate effectively through language. These abilities are often organized into frameworks such as fluid versus crystallized intelligence and models like the Cattell-Horn-Carroll theory, which identifies abilities like fluid reasoning, perceptual speed, and verbal skills.
Learning vs. Intelligence
It is crucial to distinguish intelligence from learning. Learning pertains to the acquisition and recall of facts, information, or skills. Intelligence, conversely, is the underlying cognitive capacity that enables these processes and others, representing the ability to effectively utilize learned information and cognitive functions.
Intelligence Quotient (IQ)
Measurement and Theory
Intelligence has been quantified through psychometric testing, most notably Intelligence Quotient (IQ) tests, initially developed for educational screening and later applied to various populations. The concept of a "General Intelligence" or g factor emerged, positing a single underlying ability that influences performance across diverse cognitive tasks. While IQ tests are recognized for measuring academic aptitude, their validity as a comprehensive measure of intelligence remains a subject of scholarly discussion.
Heritability and Group Differences
The heritability of IQ, the extent to which genetic factors explain individual differences in IQ scores, is a topic of considerable research. However, the scientific consensus is that genetic factors do not account for observed average differences in IQ test performance between racial groups. Environmental influences are widely considered to play a significant role.
Emotional Intelligence
Understanding and Managing Emotions
Emotional intelligence refers to the capacity to accurately perceive and convey emotions, both in oneself and others. It is believed to enhance problem-solving skills by facilitating emotional management and is closely linked to mental health and social intelligence. This form of intelligence emphasizes interpersonal understanding and emotional regulation.
Moral Intelligence
Understanding Right and Wrong
Moral intelligence is defined as the capacity to discern between right and wrong and to act in accordance with one's ethical values. It is considered a distinct intelligence, independent of emotional and cognitive capacities, focusing on ethical reasoning and behavior.
Book Smart vs. Street Smart
Academic vs. Experiential Knowledge
These contrasting concepts highlight the difference between knowledge acquired through formal study ("book smarts") and that gained through practical experience ("street smarts"). While book smarts provide theoretical understanding, they may lack practical application, whereas street smarts offer experiential wisdom but might lack a robust theoretical foundation. This distinction underscores the varied ways knowledge and competence are developed.
Animal Intelligence
Cognitive Abilities Across Species
Research into animal intelligence, or animal cognition, examines mental abilities and compares them across species. Studies focus on problem-solving, numerical reasoning, and social learning. Defining and measuring intelligence consistently across diverse species presents significant challenges. Notable examples of intelligent animals include great apes, dolphins, elephants, parrots, rats, and ravens. Evidence suggests a general factor of intelligence (g factor) is present in species like primates and mice, similar to humans.
Plant Intelligence
A Controversial Concept
The notion of plant intelligence is debated. Proponents argue that plants exhibit intelligence through their ability to sense and model their environments, adjusting morphology and physiology for survival and reproduction. Critics contend that true intelligence requires the creation and use of persistent memories, a capability they believe plants lack, distinguishing them from organisms with more complex nervous systems and learning capabilities.
Artificial Intelligence (AI)
Machine Cognition
Artificial intelligence refers to the intelligence demonstrated by machines, defined as systems that perceive their environment and take actions to maximize success. Definitions emphasize the ability to interpret data, learn, and adapt flexibly to achieve goals. While AI has made significant strides in specific tasks and benchmarks, it generally lags behind human general intelligence, often lacking common sense and robust reasoning capabilities.
Optimization and Future Potential
Some theoretical frameworks define intelligence as "optimization power"โthe capacity to steer the future into preferred states. AI systems, like Deep Blue in chess, demonstrate this by optimizing outcomes within defined domains. While AI excels in specific computational tasks, its development continues to explore the boundaries of machine cognition and its potential applications.

Social Intelligence ๐ฅ
๐ค Navigating Social Dynamics
Social intelligence involves the ability to comprehend social cues, motivations, and dynamics within interpersonal contexts. While distinct from emotional and cognitive intelligence, it shares connections with both. Research in this area explores how individuals make judgments about others and the factors influencing social perception and interaction.
