Leadership is the set of managerial or directive skills that an individual has to influence the way of being or acting of people or in a certain work group, making this team work with enthusiasm towards the achievement of its goals and objectives. It is also understood as the ability to delegate, take the initiative, manage, convene, promote, incentivize, motivate and evaluate a project, effectively and efficiently, be it personal, managerial or institutional (within the administrative process of the organization) .

Leadership does not involve an unequal distribution of power, because group members are not powerless, but shape group activities in different ways. Although, as a general rule, the leader will have the last word.

Another concept that is gaining ground in recent years is Neuro-leadership, which refers to a discipline derived from Neuroeconomics that relies on knowledge derived from psychology and neuroscience to train better leaders and achieve better business administration. .

The correlation between the leader in attraction and in ideas is positive. But because it is moderate, we must look for cases in which the functions of leadership in attraction and ideas are exceeded. In particular, there are suggestive reports from a few groups that indicate that the most frequent initiator of communications is not as attractive as might be expected from the high correlation between attraction and leadership. Although idea leaders have a 50 percent chance of being the most attractive men at the end of the first session of the group, it is highly unlikely that they will maintain the high position in attractiveness and ideas by the middle of the fourth session. Bales suggests that leaders at work do things that deflect affection from other members. In particular, Bales suggests that the senior initiator may not allow other members opportunities for reaction, comment, or feedback, such as contributions to the leader's ideas.
