Most people are extremely uncomfortable around a man who is crying. Because it is a rare event, it is assumed that very strong emotions have caused the man to cry, and that these emotions result from events that the average person, especially one not intimately connected to the individual, cannot effectively manage. It is more natural for a woman to cry in public, but it is not always appropriate, especially in the workplace. Therefore, in order to be successful in the work environment typical for most women scientists, women are well-advised to control their natural tendency to cry in response to emotions. While this may be unfair, it is important to remember that men, in similar situations, are also struggling to control their emotions.
Men are just less likely to be suppressing tears.
As children, both boys and girls express their emotions through crying. Women use numerous ways to control crying. For example, they may maintain stony silence, exhibit slow, methodical reasoning or shout. Of these options, shouting may best grab the attention of male supervisors, because it is a common male response, but it is increasingly viewed by both men and women as even less professional than crying. Many women are successful in controlling tears in the presence of male supervisors or coworkers, then cry in the privacy of their offices at the first opportunity.
