>>If you're writing entire chapters on 'igon values' Pinker's review says thatthe book "quotes an expert speaking about an 'igon value' (that’s eigenvalue,.." I haven't read the book. Are you sure that Pinker was downplaying the "igon value" issue and that Gladwell really wrote "entire chapters on 'igon values'" ? Which entire chapters are about "igon values" ?
