Blind product tests

Optimise your product tests and obtain more operational and richer information

The essential objective of a blind product test is to obtain from consumers a measure of their "overall hedonic evaluation" of a product, and in as far as is possible, understand the reasons for this evaluation.

However, the analytical capacities of the "naïve consumer" must not be exceeded. Due to a lack of experience and vocabulary, consumers are sometimes incapable of explaining with precision their overall evaluation.
Conversely, limiting consumer questioning to just their overall opinion seems a shame: Interviewing "naïve" consumers can often determine with precision the main strengths and weaknesses of a product, and potential ways of improving a proposition.

But the greatest care must be taken when deciding on the technique to employ, that is to say:

• The choice of method (test location and procedure).
• The sample structure (size, characteristics and quality).
• And the construction of the questionnaire (choice of the product descriptors).
