What was Martin Luther King Jr.'s IQ?

No IQ score for King has been published, and he was born too late for Cox's 1926 study. LifeScore uses 130+ as an editorial marker, with a range of 120 to 140, based on his early start at college, his doctorate and a body of writing still studied today.

How smart was MLK?

Very, in verbal and strategic terms. He skipped two grades, entered Morehouse College at 15, earned a doctorate in systematic theology from Boston University at 26 and won the Nobel Peace Prize at 35. His campaigns combined moral argument with careful planning of timing and pressure.

What did MLK study?

King studied sociology at Morehouse College, then divinity at Crozer Theological Seminary, where he was class valedictorian, and finally systematic theology at Boston University. His doctoral dissertation compared the ideas of God in the theologians Paul Tillich and Henry Nelson Wieman.
