“There's actually been studies, ah, where they went with one of the Polgar sisters, and they tested her memory, one with chess positions that came from actual games, and one with positions where the pieces were just randomly placed on the board, and when they were randomly placed on the board, she did pretty similar to most people, even though, again, the Polgar sisters have, like, one 60 plus IQ, so they're very, very smart but then when it came to the chess positions, they could remember those by heart”

The claim, plainly

Alexandra Botez states that cognitive memory studies on chess grandmasters like the Polgar sisters demonstrate they perform similarly to average people when recalling randomly placed pieces, but remember actual game positions by heart.

Assessment

Alexandra Botez accurately describes a famous phenomenon in cognitive psychology: chess grandmasters recall real game positions exceptionally well due to chunking, but perform similarly to non-experts when recalling randomly placed pieces. Furthermore, Susan Polgar specifically performed this exact memory test on camera in the 2007 National Geographic documentary 'My Brilliant Brain'. However, Botez misattributes this demonstration to a published peer-reviewed study on one of the Polgar sisters; the landmark academic studies establishing this finding were conducted decades earlier by Adriaan de Groot (1965) and Chase & Simon (1973) before the Polgar sisters were active grandmasters.

De Groot (1965) and Chase & Simon (1973) established that chess grandmasters perform like non-experts when recalling randomly placed pieces.
Susan Polgar demonstrated this exact real vs. random board position memory test in the 2007 TV documentary 'My Brilliant Brain'.
There are no published peer-reviewed cognitive psychology studies in which any of the Polgar sisters were experimental subjects tested on random chess piece recall.
