Berend Wierenga, Professor Emeritus of Marketing at RSM has given his opinion if and how suggestive questions may give direction to the type of answers one may answer with, especially in relations to the 'Staat van de Boer'.

Wierenga has commented that due to methodological shortcomings, the results are systematically controlled in a too pessimistic direction.
