The ?eld of sensory science has grown exponentially since the
publication of the p- vious version of this work. Fifteen years ago
the journal Food Quality and Preference was fairly new. Now it
holds an eminent position as a venue for research on sensory test
methods (among many other topics). Hundreds of articles relevant to
sensory testing have appeared in that and in other journals such as
the Journal of Sensory Studies. Knowledge of the intricate cellular
processes in chemoreception, as well as their genetic basis, has
undergone nothing less than a revolution, culminating in the award
of the Nobel Prize to Buck and Axel in 2004 for their discovery of
the olfactory receptor gene super family. Advances in statistical
methodology have accelerated as well. Sensometrics meetings are now
vigorous and well-attended annual events. Ideas like Thurstonian
modeling were not widely embraced 15 years ago, but now seem to be
part of the everyday thought process of many sensory scientists.
And yet, some things stay the same. Sensory testing will always
involve human participants. Humans are tough measuring instruments
to work with. They come with varying degrees of acumen, training,
experiences, differing genetic equipment, sensory capabilities, and
of course, different preferences. Human foibles and their
associated error variance will continue to place a limitation on
sensory tests and actionable results. Reducing, controlling,
partitioning, and explaining error variance are all at the heart of
good test methods and practices.
