Is the way you think actually normal?
In January 2020, a question went viral: do you have an inner monologue? Millions of people were startled to discover that the way they experience their own thoughts is not universal. Russell Hurlburt has spent four decades studying this. The results are more surprising than the viral debate suggested. Take the quiz to find your type.
A few quick questions about how you think. First, your age range (optional), then rate three statements about inner speech. 1 = never or rarely, 5 = almost always.
Inner seeing. Rate how often each statement applies to you.
Unsymbolised thinking and emotional experience. Rate how often each applies to you.
Sensory awareness and one final question about mental imagery.

The five types of inner experience
Hurlburt's Descriptive Experience Sampling (DES) methodology, developed over four decades, identifies five frequent phenomena that make up human inner experience. Most people experience all five at different times, but their relative proportions vary widely between individuals.
Inner speaking is hearing your own voice narrating, commenting, or talking silently. Inner seeing is visualising images, scenes, or mental pictures. Unsymbolised thinking is a direct knowing that has content but no sensory form, thinking without words or pictures. Feelings are experiencing an emotion as the primary content of the moment. Sensory awareness is attending to a specific sensory quality, such as a texture, sound, or colour.

Is it normal to have no inner monologue?
Yes. Approximately 15% of individuals experience inner speech in fewer than 10% of their sampled moments, according to Hurlburt and Heavey 2015. These individuals rely more on visual imagery, unsymbolised thinking, or sensory awareness. Having minimal inner speech is a well-documented cognitive variation, not a disorder or deficiency.
People with constant inner narration sometimes report higher anxiety. Take the social anxiety quiz to see where you score on the clinical scale.
Frequently asked questions
Inner speech exists on a spectrum. Hurlburt and Heavey (2008) found that inner speaking is present in approximately 26% of randomly sampled moments, but individual rates vary from 0% to over 75% of waking moments. The question is not binary but continuous. Most people experience inner speech in some situations but not others. This quiz measures how frequently you experience inner speech relative to your other modes of thinking.
Yes, but it often takes a different form. Research by Atkinson (2006) found that deaf people who use sign language as their primary language typically experience inner "speech" as visual-gestural imagery. They see or feel their hands signing in their mind, much the way a hearing person hears their own voice internally. Deaf people trained in oral communication may experience something closer to auditory inner speech. What hearing people call an inner monologue is really an inner language experience, and language can be visual-spatial as well as auditory. The inner experience of deaf individuals is not diminished; it is differently structured.
Yes. Dawes et al. (2020) found that the large majority of people with aphantasia report dreaming. However, their dreams tend to be less vivid, more conceptual or narrative in character, and less dominated by visual imagery. Some describe their dreams as "knowing what is happening" rather than "seeing it." Lucid dreaming is also less frequent. The fact that people with aphantasia can dream suggests that the neural mechanisms involved in dreaming are at least partially independent of those involved in voluntary mental imagery. Aphantasia affects roughly 3-5% of people. Explore how other rare traits stack up with the human rarity calculator.
The best available data from Hurlburt's DES research shows that inner speaking is present in approximately 26% of randomly sampled waking moments across the population (Heavey & Hurlburt 2008). This does not mean only 26% of people "have" an inner monologue. Nearly everyone experiences inner speech at least some of the time. The variation is in frequency. The question "do you have an inner monologue" implies a binary when the reality is a continuous spectrum.
Aphantasia is the inability to form voluntary mental images. The term was coined by Adam Zeman and colleagues in 2015. Prevalence is estimated at 2-5% of the general population. People with aphantasia can still remember, imagine, and dream, but they do so without visual imagery. At the opposite end is hyperphantasia, where mental images are nearly as vivid as real perception, affecting an estimated 3-5% of people.
Research suggests correlations but not straightforward causal links. People with frequent inner speech may report higher self-reflection and, in some cases, higher rumination and anxiety. Inner speech is also associated with better verbal working memory and self-regulation. People with dominant visual thinking tend to report stronger autobiographical memory. No inner experience type is inherently better or worse. Each type has cognitive strengths and potential vulnerabilities.
To some extent, yes. Your baseline inner experience profile appears relatively stable across adulthood, but you can cultivate new modes of thinking through practice. Mindfulness meditation has been shown to increase sensory awareness and reduce the dominance of inner speech. Journaling and cognitive-behavioural techniques can strengthen inner speech for those who want to improve verbal reasoning. The most important takeaway is that your inner experience type is not a limitation.
In January 2020, a post on Twitter/X asked whether people have an inner monologue and sparked millions of responses from people who were genuinely startled to discover that not everyone thinks in words. For many verbal thinkers, the revelation that some people have no running inner narrator was as surprising as discovering a sensory difference they had never known existed. For people with minimal inner speech or aphantasia, the moment was a recognition: they had often felt vaguely different without having language for why. Hurlburt's four decades of research had documented this variation systematically, but it had never entered mainstream awareness until social media made the experiential comparison visible at scale. The viral moment is a textbook example of how the perception gap between our own inner experience and the population distribution can persist for an entire lifetime without ever being noticed.
