It is 2am. You went to bed at 11. But somewhere between closing your eyes and falling asleep, you wondered how deep the Mariana Trench actually is, which led to how pressure works at depth, which led to the history of deep-sea exploration, which led to the biography of a Swiss physicist you had never heard of, and now you are reading about bathyspheres on your phone with one eye closed and no intention of ever using any of this information.
If this sounds familiar, you are not wasting your time. You are exhibiting a specific pattern of cognitive behavior that psychologists have studied extensively. And it turns out the mind that cannot stop exploring is wired differently in several measurable ways.
Psychologist Todd Kashdan at George Mason University has spent more than 20 years studying curiosity. His research, along with work by Jordan Litman and others, has identified curiosity as a multidimensional construct with distinct facets that predict different outcomes in personality, emotion, and well-being. Kashdan’s Five-Dimensional Curiosity Scale, validated across three studies with over 3,900 adults, reveals that curiosity is far more sophisticated than simply “wanting to know things.”
Here are seven traits the research identifies in people like you.
1. You experience joyous exploration
This is the dimension of curiosity that most closely matches the dictionary definition. It captures a preference for new information and experiences and a tendency to find the world genuinely fascinating. People who score high on joyous exploration do not need a reason to learn something. The learning itself is the reward.
Kashdan’s research found that people high in joyous exploration endorsed strong levels of openness, emotional stability, happiness, meaning in life, and satisfaction of the psychological needs for competence, autonomy, and relatedness. This dimension is linked to what earlier researchers called curiosity-as-interest: the pleasurable experience of finding the world intriguing, where exploration is driven by enjoyment rather than anxiety.
If you regularly find yourself engrossed in a topic you had no intention of studying five minutes ago, and the experience feels genuinely pleasurable rather than stressful, this is the dimension driving it.
2. You have high deprivation sensitivity
This is the less comfortable side of curiosity, and it is the one that keeps you up at night. Research on the interest/deprivation model of curiosity distinguishes between curiosity that feels good (interest) and curiosity that feels like a gap that must be filled (deprivation). Deprivation sensitivity is the awareness of information you do not know, combined with a strong drive to close that gap.
People high in deprivation sensitivity experience genuine discomfort when they encounter an unanswered question. They cannot leave a mystery unsolved or a Wikipedia article unfinished. The tension of not knowing drives them to keep searching until the gap is closed. Research found that this dimension predicted both curiosity-related interest and frustration when anticipating answers to trivia questions, suggesting it is a more complex motivational state than pure enjoyment.
If you have ever stayed up an extra hour because you could not stop until you understood how something works, that is deprivation sensitivity. It is not procrastination. It is your brain refusing to tolerate an information gap.
3. You have a high need for cognition
Research on epistemic curiosity and related constructs has found that need for cognition, defined as an individual’s tendency to engage in and enjoy effortful cognitive activity, is so closely related to epistemic curiosity that the two are nearly indistinguishable in statistical analysis. The correlation between need for cognition and openness to ideas is .78, which in psychology is remarkably high.
People high in need for cognition do not just tolerate complex thinking. They actively seek it out. They prefer problems that require thought over problems that are straightforward. They find cognitive effort inherently satisfying rather than draining. While most people are what researchers call “cognitive misers,” conserving mental energy wherever possible, high-need-for-cognition individuals treat thinking as a form of recreation.
If reading a dense explainer about quantum mechanics feels more like entertainment than work to you, your need for cognition is likely well above average.
4. You score high on openness to experience
Openness to experience is one of the Big Five personality traits, and it is the one most consistently linked to curiosity across the research literature. Research published in Current Opinion in Behavioral Sciences notes that openness is related to an appreciation for aesthetics and creativity, but even more so for cognitive stimulation, complexity, and curiosity. Of all the Big Five traits, openness is the strongest predictor of who will voluntarily engage in learning for its own sake.
People high in openness tend to have wide-ranging interests, a preference for novelty, and a willingness to engage with ideas that are unfamiliar or unconventional. They are the people who read across genres, watch documentaries about topics they know nothing about, and find conversations about abstract ideas genuinely energizing.
5. You have above-average stress tolerance for the unknown
This one is less obvious but critical. Kashdan’s five-dimensional model includes stress tolerance as a distinct dimension of curiosity. It captures the perceived ability to cope with the anxiety inherent in confronting the new, the uncertain, and the complex.
Not everyone who is intellectually curious can handle the discomfort that comes with genuinely new territory. Some people are drawn to novelty but become anxious when they encounter information that challenges their existing understanding. People high in stress tolerance can sit with that discomfort. They can hold contradictory ideas without needing to resolve them immediately. They can tolerate the feeling of being confused without interpreting it as a sign that they should stop.
Kashdan’s research found that stress tolerance was significantly correlated with well-being, indicating that people who can cope with anxiety in novel situations tend to experience greater happiness and life satisfaction. The ability to stay curious even when the territory is uncomfortable is what separates the person who skims a Wikipedia article from the person who spends two hours following its footnotes.
6. You are driven by intrinsic rather than extrinsic motivation
The hallmark of the 2am rabbit hole is that there is no external payoff. Nobody is grading you. Nobody is paying you. Nobody even knows you are doing it. The motivation is entirely internal: you want to know because you want to know.
Research on the neuroscience of intrinsic motivation has found that intrinsic motivation, the spontaneous tendency to be curious and interested and to seek out challenges, predicts enhanced learning, performance, creativity, optimal development, and psychological wellness. When people engage in an activity because they find it inherently interesting rather than because of some external reward, the quality of their engagement is fundamentally different. They process information more deeply, remember it longer, and connect it more creatively to other things they know.
Your 2am research session is not a failure of self-discipline. It is an expression of one of the most powerful motivational states psychology has identified.
7. You find that curiosity feeds your sense of meaning
A large collaborative study on curiosity and information demand found that the personality traits most strongly associated with information seeking included not just core curiosity facets but also need for cognition, thrill seeking, and stress tolerance. But beyond the cognitive dimensions, research by Kashdan and colleagues on curiosity and well-being has consistently found that on days when people report being more curious, they also report greater presence of meaning, greater life satisfaction, and more frequent growth-oriented behaviors.
This is the finding that matters most for the person reading this at 2am wondering if they should put their phone down. Curiosity is not just a cognitive trait. It is a pathway to meaning. The act of exploring, of following a question wherever it leads, of caring about something for no reason other than the fact that it is interesting, is one of the most reliable predictors of a life that feels rich and purposeful.
You are not wasting time when you fall down a rabbit hole. You are doing something your brain was designed to do. You are exercising the exact cognitive muscles that research links to creativity, happiness, meaning, and psychological flexibility.
The bottom line
If you are the kind of person who knows a little bit about a lot of things that serve no practical purpose, who cannot hear an interesting question without needing to know the answer, who treats the internet as an all-you-can-eat buffet of information, you are not scattered or unfocused or wasting your potential.
You are experiencing joyous exploration and deprivation sensitivity simultaneously. You have a high need for cognition and above-average openness to experience. You can tolerate the stress of encountering the unknown. You are intrinsically motivated. And your curiosity is feeding a sense of meaning that most people are desperately trying to find through far less effective means.
The research is clear. Genuinely curious people are not just more knowledgeable. They are happier, more creative, more resilient, and more satisfied with their lives. The 2am rabbit hole is not a problem to be solved. It is a feature of a mind that is working exactly the way it should.
