Abstract Very little actual scientific research has been carried out in I/T to date, essentially because of the lack of scientific background among I/T investigators. Major problems are found in the sampling procedures, materials, experimental conditions and tasks, quantification procedures and conclusion-drawing logic. In order to foster I/T research, methodological research training could be given to investigators, and interdisciplinary contacts and networking should be promoted. The input of I/T practitioners to I/T research can be valuable in spite of their lack of training provided they use simple methods and are supervised appropriately. Non I/T practitioners should work with practitioners.
