A quote:
"The complexity of social interaction and the difficulty in directly
falsifying memetic models means that unless we apply strong selection
criteria the field of memetics will be swamped by the forces of variation
and hence not successfully evolve. As a result of this memetics as a field
may well lose the race to others in academia and society. For this reason
the application of stringent selection processes (that are relevant to the
survival of the field as opposed to relevant to only the survival of
academics and their constructs) is vital."
