References to a figurative "man-box", an idea often attributed to TED speaker Tony Porter, attempts to describe the societal restrictions on a man's freedom of emotional expression. As Porter describes, this restriction is a primary reason for high rates of violence against women.[12] Through his organization, A Call to Men, Porter and his team organize initiatives and create awareness about what it means to possess "healthy manhood".[13] The 'man-box' is an analogous attempt to shed light on some of the cultural and social barriers we impose on men such as emotional reservedness, lack of physical intimacy with other men, and expectations of aggressive and/or dominant behavior in social environments.
