Abstract Thinking: What It Is and Why It Matters
Abstract thinking is the ability to work with ideas that aren't directly tied to concrete, observable experience. It's what lets you understand metaphors, reason from principles, solve problems you've never encountered before, and imagine things that don't yet exist.
Without it, cognition stays tethered to direct sensory experience. With it, you can think in concepts, categories, and hypotheticals — and that's where creative work lives.
What Abstract Thinking Actually Means
The term gets used loosely, but psychologists have a fairly precise definition. Abstract thinking involves representing knowledge through symbols, categories, and principles rather than through specific instances.
When you recognize that "justice" is a concept that applies across wildly different situations, or grasp that a 2% interest rate compounding over 20 years has implications far beyond the face numbers, you're engaging abstract thinking.
Jean Piaget's developmental model identified abstract thinking as the hallmark of "formal operational" cognition, which typically develops in adolescence. But adult abstract thinking capacity varies substantially and continues to develop with deliberate practice — it isn't fixed.
Abstract vs. Concrete Thinking
Concrete thinking deals with what is directly observable: this table, this conversation, this specific event. Abstract thinking deals with what the table represents, what the conversation means, what the event implies about a broader pattern.
Both are necessary. Concrete thinking keeps you grounded in reality. Abstract thinking lets you extract transferable principles and apply them in new contexts.
The problem most people have isn't that they lack abstract thinking capacity. It's that they default to concrete thinking when abstract thinking would serve them better. They solve the immediate problem instead of identifying the class of problems it belongs to — and so they solve the same problem repeatedly, slightly repackaged.
Why Abstract Thinking Matters for Creativity
Creativity, at its core, requires generating novel ideas. Novel ideas almost always come from applying an existing principle in a new domain, or combining concepts that weren't previously connected.
Both of those moves require abstract thinking.
When researchers at IDEO studied how their best designers worked, one consistent pattern emerged: they rapidly alternated between abstract principles and specific applications. They'd identify an abstract pattern — "this is a trust problem" — then apply it concretely — "so we need visible social proof at this step."
This oscillation between levels of abstraction is what researchers call "conceptual blending," and it's directly linked to creative output quality.
Dedre Gentner's work at Northwestern on analogical reasoning shows that people who can identify deep structural similarities across surface-level differences consistently generate more innovative solutions. Structural similarity requires abstract thinking to perceive.
Analogical Reasoning: Abstract Thinking in Action
One of the most practical applications of abstract thinking is analogical reasoning: taking the structure of a known problem and applying it to a new one.
NASA engineers solved a space shuttle insulation problem by studying how woodpeckers protect their brains from the impact of drilling into trees. Different surfaces, same underlying structural problem: how to protect a fragile component from repeated high-frequency impact. Abstract thinking let them strip away the irrelevant details and see the shared structure.
This kind of cross-domain transfer is exactly what the Analogical Encoding exercise trains. You read two structurally similar scenarios from different domains and extract the shared principle — the abstract skeleton underneath the specific details.
Abstract Thinking and Divergent Thinking
Divergent thinking, the ability to generate multiple distinct ideas from a single prompt, relies heavily on abstract thinking. When you're listing unusual uses for a paperclip, the people who generate the most distinct categories are operating at a higher level of abstraction.
A concrete thinker sees "a small metal wire that holds paper together." An abstract thinker sees "a small rigid material with specific physical properties: flexible, conductive, hookable, non-toxic." The second framing unlocks far more categories of use.
How to Be More Creative: 7 Science-Backed Exercises covers the alternative-uses exercise in detail. It's a direct test of this kind of abstract categorical flexibility, and the Torrance Tests of Creative Thinking use it precisely because of what it reveals about abstraction.
How to Develop Abstract Thinking
Abstract thinking isn't a fixed trait. These practices build the skill directly:
Work with principles, not just examples. When you learn something new, ask: what's the underlying principle here? What rule or pattern does this example illustrate? What other situations would fall under the same rule?
Practice analogical mapping. Take a problem you're working on and find three structurally analogous problems from different fields. What solutions exist there? Which elements transfer — not the surface details, but the underlying mechanism?
Read for reasoning structure. Philosophy, mathematics, and economics are built around abstract thinking. Read them not for conclusions but for the reasoning patterns they model. When you follow a proof or a philosophical argument, you're training your brain to operate on abstractions.
Argue both sides of a position. The ability to hold multiple abstract frameworks simultaneously and evaluate which applies is central to flexible thinking. Lawyers, chess players, and good scientists do this constantly.
Do the Remote Associates Test. The RAT presents three unrelated words and asks you to find a single connecting concept. It's a direct measure of semantic flexibility — the kind of associative abstract thinking that feeds creative insight. The Remote Associates exercise builds this specific capacity.
Abstraction and Expertise
One underappreciated finding in creativity research is that domain expertise and abstract thinking interact in complicated ways. Novices can think abstractly but lack the concrete knowledge to anchor their abstractions. Experts have deep concrete knowledge but sometimes over-rely on established categories — they see what they know, not what's there.
The most creative practitioners in any field are those who can move fluidly between concrete specifics and abstract principles. They know enough to ground their abstractions, but they haven't let their knowledge calcify into habit.
This is why convergent thinking, the analytical counterpart to creative generation, matters alongside abstraction. Abstract thinking generates the connections; rigorous evaluation narrows them to what actually works.
Abstract Thinking, Metaphor, and Lateral Thinking
Abstract thinking connects directly to metaphorical thinking — the ability to map the structure of one domain onto another. When you say "the immune system fights infection like an army defends a country," you're using abstraction to strip away biological specifics and transfer a structural pattern (hierarchical defense, rapid mobilization, targeted response) across domains.
George Lakoff and Mark Johnson's 1980 work Metaphors We Live By argued that most of human conceptual thought is organized through this kind of structural mapping. Metaphor isn't just decorative language — it's a core cognitive mechanism through which abstract thinking operates. You can't understand a metaphor without abstract thinking, and you can't generate a productive metaphor without the ability to perceive structural similarities beneath surface differences.
Lateral thinking, Edward de Bono's framework for sideways approaches to problems, also requires abstract thinking to work. The technique of random input — taking an unrelated word and forcing connections to your problem — only generates useful results if you can operate at a level of abstraction where apparently unrelated concepts share deep structural properties. Without that capacity, the random word stays random.
Cognitive flexibility is the broader umbrella that abstract thinking falls under: the ability to shift between different representational frameworks, consider multiple perspectives simultaneously, and update your mental model when new information contradicts it. Abstract thinking is what makes flexibility possible — you can only shift between frameworks if you can represent those frameworks as objects of thought in the first place. Research by Aron Barbey and colleagues at the University of Illinois showed that cognitive flexibility and abstract reasoning draw on overlapping prefrontal networks, particularly the lateral prefrontal cortex, and that training in one tends to improve the other.
For the most direct connection between abstract thinking and creative output, see divergent thinking — specifically the research on categorical flexibility, which measures how far apart the conceptual categories of generated ideas are from each other. Higher categorical distance requires more abstract thinking to perceive and produces more genuinely original ideas.
