EQ means emotional intelligence, the ability to empathize with people effectively, allowing people to take hints via social cues when they are being annoying or otherwise engaging in asshole-like behavior.

As geniuses are already extreme outliers. For one thing, they do not typically fit in very well with their peers, often leading to seemingly anti-social behavior.

None of the articles you link directly correlate EQ to intelligence, they corrleate it to civic minded ness, and getting good grades in school. Social people do well in social environments is not surprising.
