According to the MBA mission statement:
MBA is dedicated to proactively researching human visual aesthetics, including its biological and mathematical bases, and to utilizing the results of that research to develop and provide information and technology with which to analyze and positively modify (i.e. improve) human visual attractiveness.
MBA believes that this information and technology can empower individuals within our species to have a greater and more clear understanding of human attractiveness and its role in our behaviour. Further we believe that this understanding can and will give each of us a more positive control over human attractiveness and ultimately over our own lives and fate.
Well, if nothing else, they’ve successfully demonstrated that people look better without lots of black lines drawn on their faces. You need to look at the ‘our research’ section to get the full glory of the MBA system. I will exercise great restraint and simply say that I find the theoretical underpinnings unconvincing.
