Here are three common habits observed in this group, according to Dr. Mark Travers, a psychologist from the US, and several international scientific studies.

Avoiding arduous tasks

According to Mark Travers, conventionally, avoiding difficult or complex tasks is often perceived as a lack of effort. However, in many cases, this reflects an optimization mindset. Intelligent individuals frequently seek more effortless solutions, such as automating, simplifying processes, or eliminating unnecessary steps.

A study published in the journal Neuroscience & Biobehavioral Reviews indicates that intelligent individuals often exhibit lower levels of brain activation when performing cognitive tasks. In other words, their brains operate more energy-efficiently and effectively.

This suggests that in a work environment, intelligent individuals typically focus on improving systems rather than merely completing tasks according to existing procedures.

Prioritizing sleep

Sleeping in or napping is often associated with a lack of discipline. However, numerous sleep studies indicate that adequate sleep is among the most critical factors for cognitive performance.

A study published in Scientific Reports examined the relationship between fluid intelligence and sleep patterns, specifically the phenomenon of "sleep spindles." These bursts of brain activity occur during certain sleep stages, playing a core role in memory consolidation and the ability to acquire new knowledge.

This helps explain why sufficient sleep is directly linked to the ability to concentrate, memorize, and make decisions. Conversely, sleep deprivation can significantly impair thinking performance, emotional control, and information processing speed.

Therefore, some individuals tend to maintain habits of getting adequate sleep, even regular naps, not viewing this as self-indulgence but as a method to preserve optimal brain performance.

Disregarding trivial matters

In many environments, quick reactions and engagement in every debate are often highly valued. However, choosing not to react in many situations is a sophisticated manifestation of emotional intelligence (EQ).

According to a study published in the journal Frontiers in Public Health, individuals with high EQ possess superior stress management abilities thanks to a mechanism called "psychological detachment."

This is the ability to temporarily shield oneself from environmental stressors, especially after work hours. This capacity is closely linked to sustainable mental health and overall happiness.

Sometimes, this behavior leads them to be perceived as indifferent. However, according to Dr. Mark, from a mental energy management perspective, this is a deliberate choice to focus on more important goals.

Experts caution against absolutely equating these habits with "intelligence." Each behavior depends on context, work environment, and individual characteristics.

However, a common thread is that individuals with a tendency for cognitive optimization often prioritize efficient energy use over maintaining a state of constant busyness.
