Have you noticed some of the smartest people you know aren’t very social? Science explains why: highly intelligent individuals often have fewer friendships and feel less satisfied by frequent socializing.

Humans evolved to thrive in small groups, and most people are happier with close social ties. However, a 2016 study found that for people with high IQs, more socializing often led to less life satisfaction.

Highly intelligent individuals tend to prioritize meaningful goals, prefer deep relationships over many acquaintances, and find joy in solitary pursuits like creating, coding, or writing.

This doesn’t mean they dislike people; rather, constant socializing can feel draining compared to fulfilling personal projects. Their happiness comes more from quality connections and meaningful work than from busy social calendars.

Ultimately, preferring fewer friends isn’t a flaw—it’s often a reflection of how their brains are wired for deep focus, long-term goals, and a unique path to happiness.
