Absolutely not.  We are scientific.  There is no science involved with psychics and mediums.  Adding them into the equation ups the "subjective" nature of a case 10-fold.  We focus on tangibles - not feelings.

Additionally - we have not seen any concrete evidence that suggests psychics and mediums are even legitimate.  In fact - 2 of the most well known paranormal psychics/mediums have both been caught fabricating evidence and information.  These 2 are Derek Acorah (formerly of "Most Haunted" fame) and Lorraine Warren (Original investigator of the Amityville case).
