The need of societal impact of research or research project is nowadays highlighted not only by the University but by each and every research funding source. Societal impact has many faces, to the extend, that everyone knows it, but nobody can say how it really looks or should look like. One thing is clear, research or knowledge, must have an impact on people in general, preferably, a positive impact. The number of reads, or attendance could be, and often is, used as a measure of the societal impact of research. However, the actual outcome of how the obtained knowledge has effected a person is, from that numbers, unknown.
