what the psych book has to say on the concept of whale telepathy

"Without evidence, claims about self-help products are nothing more than marketing strategies. It is invalid to say that because scientists have been unable to prove that whales are not telepathic, whales must have this ability. The "you can't prove it's wrong" list is infinitely long. If scientists want to argue for the telepathic ability of whales, then it is their responsibility to present evidence for such an ability."
