Baron-Cohen argues that systemising ‘needs an exact eye for detail, since it makes a world of difference if you confuse one input or operation for another.’ (Baron-Cohen, 2003), p. 64. However, it seems to me that one could just as plausibly argue that good empathising requires attention to detail, because otherwise you might, for example, fail to notice the important emotional leak that tells you what the other person is really feeling, or how you might be best able to make him or her feel better.
