An article on the American Psychological Association website titled True lies: People who lie via telling truth viewed harshly, study finds (December 15, 2016) defines paltering: “the ability to deceive someone by telling the truth… Rather than misstating facts or failing to provide information, paltering involves actively making truthful statements to create a mistaken impression”

Merriam Webster: “to act insincerely or deceitfully : equivocate.”
The Free Dictionary: “To talk or act insincerely or misleadingly; equivocate.”
