lots of important new ideas here make this definitely worth reading. however, it doesn't "overturn everything" we know about human perception and this author along with a lot of other "new" psychologists would benefit from a more thorough study of what has been known and remains true. in this case i will mention perception of the neutral density spectrum (black-grey-white) as particularly uninformed, though even here there are contributions - just not the revolutionary and "overturning" sort the author hypes. believe it or not, in the early 20th century, by the time i graduated in 1968, perception psychology had already solved a great many mysteries and those solutions stand up quite well because the studies were well and elegantly designed and done. wolfgang koehler and hans wallach, for instance, are among the gestalt psychologists who showed us many things and whose writings are just as interesting as "the latest" stuff.
i think the section on illusions and perception of the future alone is probably reason enough to buy this book.
