Respect for a human being and perceiving an employee as a source of knowledge and not only a source of costs are the features of modern organization. Sharing knowledge and its popularizing are the key factors underlying competitive advantage of an organization. Possessing knowledge does not grant an efficient realization of the aforementioned processes. If so, why are the employees so reluctant to share this immaterial substance, which they do not loose by its exchange? Are they evaluated only for possessing knowledge or for sharing it as well? The article describes the results of a pilot study, carried out among the high school and university students, on the consciousness of the significance of sharing knowledge. The preliminary results indicate that the students who achieve the highest marks do not belong to the group of those who are the most eager to share their knowledge with others.
