Is Epistemic Curiosity a Personality Trait? Understanding I-Type and D-Type
Introduction
Have you ever found yourself falling down a Wikipedia rabbit hole at 2:00 AM, not because you had to, but because you simply couldn’t stand not knowing how a specific historical event unfolded? Or perhaps you are the type of person who feels a physical sense of frustration when a puzzle remains unsolved or a complex concept remains unexplained. This drive isn’t just a passing whim; it is a fundamental part of how your brain processes information.
To answer the central question: Yes, epistemic curiosity is considered a personality trait. Rather than being a temporary mood, it is an enduring drive to acquire new knowledge, ideas, or concepts that stimulates intellectual interest 1. While many people conflate curiosity with a general “openness to experience”—a common facet of the Big Five personality traits—psychologists view epistemic curiosity as a more specific, structured mechanism of the mind.
The Two Faces of Curiosity: I-Type vs. D-Type

Not all curiosity feels the same. Research suggests that epistemic curiosity isn’t a single, uniform impulse. Instead, it manifests through two distinct personality profiles: I-type and D-type curiosity 1. Understanding which one resonates with you can help you recognize why you approach learning and problem-solving in certain ways.
I-Type: The Explorer
I-type (Interest-type) epistemic curiosity is characterized by an active, joyful desire to discover something entirely new or to explore fresh opportunities for discovery 1. If you have high I-type curiosity, you aren’t necessarily looking to “fix” a gap in your knowledge; you are simply drawn to the thrill of the new. A hallmark behavior of this type is the tendency to say, “When I learn something new, I like to find out more about it” 1.
D-Type: The Resolver
D-type (Deprivation-type) epistemic curiosity is driven by a different mechanism: the need to eliminate “informational deprivation” 1. This is the discomfort of not knowing something specific. While I-type curiosity is about the joy of discovery, D-type curiosity is about the relief of resolution. People high in D-type curiosity may show recognizable behaviors such as working harder or feeling significant frustration when they cannot solve a problem or fill a specific gap in their knowledge 1.
Key Differences at a Glance
The following table breaks down the primary distinctions between these two intellectual drivers to help you identify your own patterns.
| Feature | I-Type (Interest) | D-Type (Deprivation) |
|---|---|---|
| Primary Motivation | The joy of finding new information 1. | The need to close a knowledge gap 1. |
| Emotional Driver | Excitement and intellectual stimulation. | Discomfort or frustration from “not knowing.” |
| Core Behavior | Exploring new topics for the sake of it 1. | Working intensely to solve a specific problem 1. |
| Trigger | New opportunities for discovery. | An existing knowledge set that feels “incomplete.” |
What Epistemic Curiosity Is Not

To understand this trait fully, it is helpful to distinguish it from other forms of interest that often get lumped together in casual conversation.
- It is not Perceptual Curiosity: While epistemic curiosity focuses on the drive to acquire facts, ideas, and concepts, perceptual curiosity is more about the desire to explore one’s physical surroundings—such as wanting to see what is inside a box or exploring a new physical landscape 1.
- It is not just “Openness”: While trait curiosity is often considered a facet of the Big Five personality factor “openness to experience,” epistemic curiosity is a more specialized intellectual drive (Competitor Insight).
What is an example of epistemic curiosity?
Because this is a personality trait, it shows up in consistent, everyday habits. Here are a few ways it might look in real life:
- The I-Type Example: You are reading an article about ancient architecture and a random mention of a specific type of stone catches your eye. You spend the next hour reading about stone masonry, not because you have a project, but because the topic itself is fascinating.
- The D-Type Example: You are watching a mystery movie and a plot hole suddenly becomes apparent. You feel an itch of annoyance and cannot focus on anything else until you’ve paused the film to mentally reconcile the logic or searched for an explanation online.
Why This Matters for You

Recognizing your specific type of curiosity isn’t just an academic exercise; it can help you manage your energy and your career.
If you identify as I-type, you likely thrive in roles that require constant innovation, brainstorming, and variety. Your challenge may be “breadth over depth”—you might start many things but struggle to finish them because a new, shinier idea has appeared. Understanding this can help you create systems to ensure your exploratory nature doesn’t lead to unfinished projects.
If you identify as D-type, you are likely a natural problem-solver and an expert at deep work. You have the grit to push through frustration until a solution is found. However, your challenge may be “tunnel vision”—you might become so obsessed with filling a specific knowledge gap that you miss the bigger picture or experience unnecessary stress when a problem is unsolvable.
Note: Personality traits exist on a spectrum. Most people will exhibit elements of both I-type and D-type curiosity, but one will likely be more dominant in their daily behavior.
