Is intelligence heritable? Karl-Friedrich Fischbach and Martin Niggeschmidt show that "heritability" means something different in biological terminology than in everyday language - which almost inevitably leads to misinterpretations. They explain why twin studies are controversial - and why genetic predictions of IQ and "educational attainment" must be treated with skepticism.
