Steven Pinker's next book project will be a style manual for the 21st century, a competitor to Strunk and White incorporating modern linguistics and cognitive science.

Judge by Pinker's next book published after 2011-11-10. True: that book is a writing style guide aimed at modern readers, presented as an alternative or successor to Strunk and White, and drawing on linguistics and cognitive science. Mostly true: the next book is such a style guide but a minor detail differs (e.g. it does not explicitly position itself against Strunk and White). Mostly false: a style manual was published but was not his next book (another book came first), or a different kind of book on writing was published. False: his next book was on a different subject and no such style manual was published.

   “by Steven Pinker ‧ RELEASE DATE: Sept. 30, 2014”

   “Pinker attempts to provide a writing style guide that is informed by modern linguistics, science and psychology, regarding the existing style guides such as Strunk and White's Elements of Style as outdated and dogmatic.”

3. E3 The Sense of Style - Wikipedia Wikipedia · 4 February 2015

   “The Sense of Style: The Thinking Person's Guide to Writing in the 21st Century is a 2014 English style guide written by cognitive scientist, linguist and popular science author Steven Pinker.”

4. E4 Science behind good writing Irish Examiner · 22 November 2014

   “Despite its title, however, Pinker’s latest is not simply a style guide in the vein of Strunk and White.”

E3 describes The Sense of Style: The Thinking Person's Guide to Writing in the 21st Century as Pinker's 2014 English style guide, and E1 gives its release date as September 30, 2014. E2 says the book is informed by modern linguistics, science and psychology and treats Strunk and White's Elements of Style as outdated, so it is presented as an alternative to that guide. E4, a 2014 review, calls it "Pinker's latest" and says it is more than a plain style guide, which does not change what kind of book it is. No evidence shows another Pinker book published between the claim and 2014, and the claim had no deadline.
