If you are skeptical, you're not alone. The NY Times Freakonomics blog has a long post by Ian Ayres dedicated to refuting Sivers's assertion, and arguing that "this talk is reckless and at times just plain wrong." Ayres contends Sivers has misrepresented the scientific evidence and that "there are many discrepancies between Sivers's description and the published description of experiments." Have a look at the three minute-video TED talk and Ayres post and decide for yourself -- when it comes to goals, is it better to tell or not to tell?
