"The so-called co-efficient of heritability, which I regard as one of those unfortunate short-cuts, which have often emerged in biometry for lack of a more thorough analysis of the data."

Previous Quote

The first job of the historian and of the journalist is to find facts. Not the only job, perhaps not the most important, but the first. Facts are the cobblestones from which we build roads of analysis, mosaic tiles that we fit together to compose pictures of past and present. There will be disagreement about where the road leads and what reality or truth is revealed by the mosaic picture. The facts themselves must be checked against all the available evidence. But some are round and hard--and the most powerful leaders in the world can trip over them. So can writers, dissidents and saints.
