Gender Differences and Deception

I recently participated in an interview with Dr. Kingsley Stewart from the radio program "Up Front" on Newstalk 93 FM in Kingston, Jamaica. The topic for the week was deception, with some of the focus directed on gender differences when it comes to deception. I would like to continue this discussion and ask two things;

1) Do you think men or women are better at being deceptive?

2) Do you think men or women are better at detecting deception?
