Abstract

Simon Baron-Cohen Allen Lane, £16.99, pp 263 ISBN 0713996714 Rating: ![Graphic][1] ![Graphic][2] ![Graphic][3] Men and women have different brains. This notion has been the subject of increasing scientific analysis, media interest, and pulp psychology of the “men are from…” variety. Now, Simon Baron-Cohen (professor of psychology at Cambridge University) has drawn on 20 years of clinical and academic experience and attempted to summarise the research on this subject—an impressive proportion of which is his own—and its implications for the future. Baron-Cohen argues that there are three kinds of normal human brain: “empathising” (type E), “systemising” (type … [1]: /embed/inline-graphic-1.gif [2]: /embed/inline-graphic-2.gif [3]: /embed/inline-graphic-3.gif

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
