Well, I think it bears pointing out that there is absolutely no evidence that either werewolves or vampires exist at all beyond mythology and
symbolism. Having said that, I imagine that the difference in psychic abilities between vampires and werewolves has to do with their very different
representations. What I mean by this is that a vampire is held to be a creature which preys on Humanity by blending in and by seducing its victims.
Vampires are often depicted as suave, sensual, sexual creatures and many have argued that the entire concept of a vampire is an attempt to define the
darker characteristics of human sexuality. It is arguable that, if they existed, vampires would utilise psychic abilities to better enable them to
move amongst humans undetected and to lure and seduce their prey. This argument can be seen in any number of incarnations of the vampire mythos. In
the classic Dracula
, for example, the famous Count is portrayed as having significant psychic powers
of telepathy, mind control and pyrokinesis. He uses these powers to lure both Renfield and Lucy Westenra and seduce them both to his will.
Similarly, the more recent Interview With the Vampire
by Anne Rice portrays
vampires with enormously powerful psychic abilities, which they too use to charm and beguile mortals, to better move amongst them unfettered. So we
can see that psychic powers complement the image of the vampire as a sensual, manipulating creature.
Werewolves, on the other hand, are most often portrayed as incarnations of savagery and Humanity's more bestial aspects. Whereas a vampire might
choose its victims with great care, werewolves are normally depicted as being far less fussy when it comes to choosing dinner. For this reason, the
traits commonly associated with werewolves are more in line with its depiction as a powerful, wild force of nature. Werewolves are thusly portrayed as
being extremely fast, extremely strong and extremely savage. Note that these are all physical characteristics. Since werewolves are a symbol of
Humanity's animal side, it is only natural that depictions of them would focus on purely physical attributes. Werewolves have traditionally been
depicted as acting more on primal animal instinct than on cunning, guile and deception. Simply put, werewolves do not need psychic powers, so they are
not portrayed as having them.
There have been exceptions to this rule, however. In the classic An American Werewolf
, the werewolf is depicted as having mild psychic powers that enable him to communicate with the dead, although this is more in the
form of a curse than innate abilities.
From our portrayals of werewolves, it is assumed that if a werewolf were to choose their victim in advance, that they would simply kill them. As
symbols of savagery, they are not afforded psychic powers since they do not need them in the same way a vampire might. I hope this helped answer your
