It's well known that women are at a disadvantage in business negotiations when compared to their male counterparts. Studies show that even when women "lean in" and push for raises and promotions, they're not able to achieve the same results as men. But a new research paper published by Organizational Behavior and Human Decision Processes, and cited by the Harvard Business Review, suggests that this bias against women is so ingrained that it even extends to men with more feminine facial features like smaller noses, fuller lips, and less-prominent eyebrow ridges.
