We conduct an online experiment with 1,677 participants (477 groups) where group members can communicate with each other via a novel video chat tool. Our key findings are that (i) larger groups lie more, (ii) all-male groups stand out in their proclivity to lie, (iii) already the first female in a group causes an honesty shift, and (iv) group behavior cannot be fully explained by members' individual honesty preferences.
