1. Intelligent People Struggle To Let Things Go Until They Make ‘Sense’

In my work as a psychologist, I regularly hear some version of the same complaint — not from the person experiencing it, but from the people around them. A conversation ends, a decision is made and most people move on.

But one person at the table keeps returning to it: an explanation that did not quite add up, an argument that was closed without being resolved, a comment that sat strangely but nobody else seemed to notice. To those around them, it looks like an inability to let things go. To the person themselves, it often feels the same way.

What is actually happening has a name in the psychological literature: need for cognition. It describes the dispositional tendency to seek out, engage in and enjoy effortful thinking — and, critically, to feel genuine discomfort when understanding remains incomplete.

The construct was first formalized by Arthur Cohen and colleagues, who defined it as the “need to structure relevant situations in meaningful, integrated ways,” and found that when this need was frustrated, it produced “feelings of tension and deprivation” that drove continued attempts to reach understanding.

The reason this matters for intelligence specifically comes from a 2025 preregistered multi-level meta-analysis published in the Journal of Intelligence, which synthesized data from over 25,000 participants across multiple studies. The analysis found consistent, statistically significant correlations between need for cognition and fluid intelligence, crystallized intelligence and general intelligence. Higher cognitive ability and the drive to keep thinking until things are resolved tend to come packaged together.

The practical consequence is the tick itself. A mind genuinely motivated to achieve understanding will resist closure that feels premature. When a conversation ends without a real answer, when a situation is explained away rather than actually explained, the discomfort is not neurotic or petty. In fact, it reflects a cognitive system doing what it is built to do and being prevented from finishing.

Most people are comfortable with having an approximate understanding. People high in need for cognition are not, and the research suggests that’s a function of how their minds are wired, not a choice they are making.

2. Intelligent People Freeze Up On The Tiniest Decisions

The second pattern is less emotionally charged but arguably more socially embarrassing. It is the experience of spending an unreasonable amount of time on a decision that, by any objective measure, should not require it. Which television series to watch. What to order at a restaurant you have been to a dozen times. Whether to reply to a message now or later.

This paralysis tends to provoke exasperation in others and sometimes even shame in the person experiencing it. It looks less like intelligence and more like an inability to function.

What is actually happening involves a cognitive orientation psychologists call maximizing. Psychologists introduced the distinction between people who instinctively search for the best possible option and those who stop once an option is sufficiently good. But over the last two decades, researchers discovered something important: many of the apparent costs of maximizing were being confused with a different trait entirely — indecisiveness.

More recent research suggests that the tendency to seek the optimal outcome and the tendency to become psychologically stuck are not the same thing, no matter how similar they might appear to be. That distinction matters because the caricature of the intelligent overthinker is often wrong. The problem is not necessarily that the person cannot evaluate options. It’s often that they can evaluate too many options at once.

A mind with a strong analytical capacity generates alternatives rapidly. It simulates outcomes, predicts future regret, compares dimensions simultaneously and keeps searching because another possibility remains imaginable. Under the right conditions, this is exactly what produces excellent judgment.

But under the wrong conditions, the machinery scales indiscriminately. The same process that can improve a career decision or a complex problem can also become activated while scrolling through a streaming menu or deciding whether a text message should be answered now or in ten minutes.

Recent research has also shown that maximizing behaves less like a strategy used selectively and more like a stable decision style that generalizes across domains. People who maximize in important life decisions often maximize in ordinary ones as well. The cognitive process does not automatically recognize that the stakes have changed.

The link to intelligence is therefore more subtle than “smart people are bad at deciding.” Analytical intelligence depends heavily on the ability to model multiple possibilities and resist premature closure. Those capacities are enormously useful. But the same cognitive strengths that allow a person to see more possibilities also create more branches to evaluate. Maximizers are not necessarily poor decision makers. They may simply be very good at a form of analysis that does not always know when its job is finished.

Both these patterns share the same underlying dynamic: a mind calibrated for depth that does not easily shift registers when the situation is shallow. This can look like instability or indecision from the outside. It often feels that way from the inside as well. But the research suggests something more precise is happening — not a deficit, but a characteristic. One that is worth understanding accurately before deciding what, if anything, to do about it.

If you don’t think you’re conventionally “intelligent,” you’re probably just unaware of your cognition style. You can take my short and science-inspired Cognition Style Test to know where your cognitive strengths lie.
