Which is more important: IQ or EQ?

Both matter. IQ determines capability range; EQ determines whether you use that capability effectively and sustainably. Research shows EQ predicts success better in most real-world contexts.

Can you improve your IQ?

IQ remains relatively stable after early adulthood. You can improve specific cognitive skills, but overall IQ doesn't change significantly. EQ, by contrast, improves readily with practice.

Why does EQ change while IQ stays relatively fixed?

EQ reflects learned emotional habits, self-awareness, and interpersonal skills—all trainable through practice and reflection. IQ reflects foundational cognitive architecture that's relatively stable.

Can high IQ people score low on EQ?

Frequently. Intellectual capability doesn't automatically translate to emotional regulation, empathy, or social awareness. Many brilliant people struggle with emotional intelligence.
