Picture a leader - Is she female?
What do you think when asked for a good executive? Is the person female or male?
Various studies prove that men and women when asked to draw a good executive almost always paint a male leader. Even if the person is painted gender-neutral, character traits which are considered to be typically male are attributed to the executive.
Based on this study, the cognitive bias of men and women becomes very clear. Cognitive biases are a systematic distortions of perception. Our brain often uses old, routine ways of thinking to be able to handle the mass of information that reaches us daily and to be able to make decisions quickly. However, it is precisely this unconscious cognitive bias that makes it so difficult to change people's view on e.g. female executives. The first step towards overcoming this is the recognition of the bias, the next: becoming active.
