The number of stars indicates quality. When people see a book title suggesting (like in "Flim-Flam! Psychics, ESP, Unicorns, and Other Delusions") that ESP is a mere "delusion", it is possible that they are not willing to give very high ratings to that book. I have already mentioned on this forum that apparently 41% of Americans believe in ESP: http://www.livescience.com/16748-americans-beliefs-paranormal-infographic.html (I suspect the number of Americans who really believe in ESP is actually much higher, and close to 100%, but they are not necessarily ready to admit it in a poll).
Now, regarding Renier's claims, even if some moderate and polite skepticism is appropriate (and perhaps sometimes even more than that, see Daylightstar's post above), I think they are not necessarily as absurd and illogical as they may seem at first sight. Take for example her "prediction" of the assassination attempt on Ronald Reagan. This idea was probably present in John Hinckley, Jr.'s mind a few hours before he shot at Reagan, and even also perhaps a few months before. Then, Ms. Renier, who is perhaps a sensitive lady with an interest in criminal affairs, could have correctly perceived this idea through ESP or telepathy, way before the crime took place. There is nothing irrational and unscientific here.
Seriously?????????
