What is Judit Polgár's IQ?

A quick, honest note. This number circulates online with no traceable origin. We publish it because you came to read it, and label it what it is: lore.

Where does the 170 number come from?

Her father László Polgár argued before his children were born that geniuses are made, not born, and set out to demonstrate it by home-educating his three daughters in chess from early childhood. All three became exceptional; Judit became the strongest female player in the game's history and beat a string of world champions.

Table 1 · Every thread behind the figure, and how much weight it can carry.

That is a stronger claim about the origins of ability than any IQ number could support, and it cuts against the framing this collection usually gets read through. Whatever her reasoning score, the documented input was roughly a decade of deliberate, structured practice from age four.

The 170 has no source and adds nothing.

How rare would a 170 IQ be?

If the 170 figure were literally true, it would be extraordinarily rare — rarer than1 in 652,598 people. That alone is a good reason to treat any confident-sounding celebrity IQ number with a raised eyebrow.
