What is an Emotional Intelligence (EI)?
Emotional intelligence is the ability to recognize and manage your own emotions and to read and respond to others' — commonly framed as self-awareness, self-regulation, motivation, empathy, and social skill. PMI's people domain leans on it heavily: roughly half the PMP exam is scenarios where the right answer is the emotionally intelligent one.
The reliable exam pattern: acknowledge first, react never, investigate before deciding, and address people privately. The answer that starts with listening usually beats the answer that starts with policy.
Worked example
A star engineer turns abruptly combative in meetings. The low-EI response is a warning about professionalism. The PM instead asks privately how things are going — and learns his visa renewal is in limbo. One HR escalation later, the "attitude problem" is gone, because it was never an attitude problem.
