Compared with traditional resumes, Linkedin resumes were less deceptive about the kinds of information that count most to employers, namely an applicant's prior work experience and responsibilities, but more deceptive about interests and hobbies. The results stand in contrast to assumptions that Internet-based communication is more deceptive than traditional formats . . .That is from the abstract of the paper "The Effect of Linkedin on Deception in Resumes" by Guillory and Jeffrey T. Hancock (March 2012). Alas the full paper is not available online.
