Daydreaming & Self-Talk: Signs of High Intelligence, According to a Psychologist

The modern workplace often glorifies constant focus and measurable results, leading to a dismissal of behaviors that might appear unproductive. Daydreaming during a task or muttering to oneself even as organizing thoughts can be misconstrued as signs of distraction or disorganization. But, emerging research suggests these so-called “annoying” habits may actually indicate higher intelligence, reflecting complex cognitive processes at work. Psychologist Mark Travers, a columnist for Psychology Today, explores this counterintuitive idea, drawing on recent studies that challenge conventional wisdom about productivity, and thought.

The Creative Spark of Daydreaming

For years, mind-wandering – when attention drifts from the present task to self-generated thoughts – has been viewed as a lack of concentration. But recent investigations suggest it can be a powerful driver of creative thinking. Travers cites a 2025 study involving over 1,300 adults, which found that deliberate mind-wandering, intentionally allowing oneself to daydream, correlated with improved creative performance. The study, published in ScienceDirect, suggests that a wandering mind isn’t necessarily an idle one.

Neuroimaging data from the study revealed increased connectivity between brain networks associated with executive control and the default mode network, which is linked to imagination and internal thought. This suggests that daydreaming isn’t simply a mental escape, but a process where the brain actively integrates information and explores new possibilities. A separate study, published in 2024 in PNAS Nexus (link), analyzed spontaneous thought samples from over 3,300 participants using natural language processing. The results indicated that these thoughts often revolve around relevant goals and contribute to memory consolidation – meaning that seemingly random mental “noise” can serve adaptive cognitive functions.

However, Travers cautions that the benefits of daydreaming are contingent on balance. If the mind wanders excessively, hindering concentration and self-awareness, it can become counterproductive. A healthy approach involves allowing for periods of focused thought interspersed with intentional moments of mental exploration.

The Cognitive Scaffolding of Talking to Yourself

The second habit often perceived negatively is internal dialogue, whether conducted silently or aloud. While it may seem unusual to an outside observer, psychology links this practice to self-regulation, planning, and metacognition – the ability to reflect on one’s own thoughts. A 2023 study published in Behavioral Sciences (link) found a significant correlation between frequent use of self-talk and higher levels of self-regulation and self-concept clarity among university students.

Participants who engaged in more frequent internal communication reported a clearer sense of identity and a greater capacity to organize their behavior. According to Travers, this internal dialogue functions as a “cognitive scaffolding” – a tool for structuring complex ideas, sequencing actions, and monitoring progress. By externalizing thoughts, even in whispers, the brain can reduce mental clutter and organize abstract or emotionally charged problems. This process can transform scattered thoughts into concrete plans.

Like daydreaming, this habit also requires moderation. When it devolves into constant rumination or harsh self-criticism, it can negatively impact well-being. However, when used constructively, it can be a powerful tool for problem-solving and self-improvement.

Implications for Workplace Culture

These findings have significant implications for how we approach productivity and assess employee behavior. A rigid focus on constant output and visible activity may stifle the very cognitive processes that drive innovation and effective problem-solving. Organizations that recognize and accommodate these “annoying” habits – by allowing for flexible work arrangements, encouraging breaks for mental exploration, and fostering a culture of psychological safety – may unlock greater creativity and resilience within their workforce.

The traditional emphasis on minimizing distractions and maximizing focus may be misguided. Instead, a more nuanced approach that acknowledges the value of internal mental processes could lead to a more productive and fulfilling work experience. This isn’t about advocating for unfettered distraction, but rather recognizing that the brain’s natural tendency to wander and reflect is not necessarily a sign of weakness, but potentially a source of strength.

The Role of Attention Residue in Task Switching

While embracing these habits, it’s crucial to understand the pitfalls of constant task-switching. Mark Travers’s work also highlights the concept of “attention residue,” the lingering cognitive activation that remains after shifting from one task to another. As he detailed in a Forbes article, the brain doesn’t truly multitask. it switches rapidly between tasks, incurring a cognitive cost with each transition. This residue slows thinking, reduces accuracy, and contributes to mental fatigue.

Sophie Leroy’s research, foundational to understanding attention residue, demonstrates that even when individuals believe they’ve fully moved on to a new task, a portion of their mental capacity remains tethered to the previous one. This underscores the importance of mindful transitions – taking a moment to mentally disengage from one task before fully immersing oneself in the next.

Looking Ahead: Cultivating Cognitive Flexibility

The key takeaway isn’t to eliminate all attempts at focus, but to cultivate cognitive flexibility – the ability to seamlessly transition between focused attention and periods of mental exploration. This involves recognizing the value of both states and intentionally creating space for each. Further research is needed to fully understand the optimal balance between focused work and mindful wandering, but the emerging evidence suggests that embracing these “annoying” habits, within reasonable bounds, can be a pathway to greater creativity, productivity, and overall well-being.
