Text: The final straw was surely the grotesque affair of Richard Herrnstein and Charles Murray's The Bell  Intelligence and Class Structure in American Life . This book came close to claiming that, given your genes, it makes no difference to your economic success whether you grew up in Scarsdale or the South Bronx.
Entailment: Hernstein and Murray say genes matter more than circumstances.
Contradiction: Herstein and Murray say where you grow up matters more than anything else.
