Nevertheless, categorization may include bias in other psychological process, notably an amplification of the perceived differences between groups associated with a reduction of the perceived differences within groups (Gold-stone et al 2001) and could influence hedonic judgment that way. In addition, the number of missing values induced by tis protocol in terms od preference (see part 3 of the data analysis section) is too large to enable analysis of individual differences. For these reasons, this study cannot be consideredas a real preference study and have to completed with a dedicated protocol with monadic presentation of the samples (one after the other), including quota considerations for recruitment of the consumers.
Is it also worth to note that the subjects were not chosen so as to obtain a representative group. However, it is assumed that the subjects were not used to tasting water in sensory analysis experiments (“naive” subjects) and the results are supposed to be consistent and representative of a mean preference for the product
Finally, free sorting is a useful tool to grasp the sensory space of water, but this methodology cannot be used as aroutine procedure as the projection of new samples on the map needs a new evaluation of the samples already tasted (this method does not enable “data aggregation”)

Cuaj kaum, categorization tej zaum yuav muaj xws li kev tsis ncaj ncees rau lwm cov kev puas hawv, tus amplification notably ntawm tus dab tsi sib txawv ntawm ib pawg kab mob uas yuav txo tau ib tug ntawm lub dab tsi txawv li cov pawg (pob zeb kub li al 2001) thiab muaj feem xyuam rau txoj hedonic txiav txim li ntawd mas. Nyob sib ntxiv, cov uas ploj lawm qhov tseem ceeb vim raug yuam los ntawm tis raws tu qauv nyob hauv cov ntsiab lus uas od xum (xyuas Tshooj 3 ntawm sab lus tsom xam ntaub ntawv) yog ib yam nkaus thiab loj mus pab tsom xam txog ib tug neeg txawv. Li no, txoj kev tshawb no yuav tsis tau consideredas ib tug tseem nyiam kawm thiab tau tag nrog ib saab raws tu qauv rau kev monadic kev nthuav qhia tus kuaj (ib tug tom qab), xws li quota xav txog kev teem rau recruitment ntawm qhov tau txais kev pab. Yog nws tseem muaj nqis los nco ntsoov tias lub compound twb tsis xaiv sij tau ib pab pawg neeg sawv cev. Tiam sis, nws yog assumed tias yaam kws yog tsis siv los tasting cov dej nyob hauv kev piav thoob hlo tsom thwmsim ("naïve" compound) thiab soj ntsuam yuav tsum tau zoo ib yam thiab sawv cev ntawm lub xum phem rau qhov khoom Thaum kawg, dawb sorting yog ib tug uas pab tau muab qhov kev piav thoob hlo chaw dej, tiam sis qhov vib this yuav siv tsis tau raws li aroutine txoj kev raws li tus projection ntawm kev kuaj tshiab nyob rau hauv daim ntawv qhia no yuav tsum tau kuaj xyuas ntawm qhov kev kuaj twb tsis tshiab (hom no tsis pab kom "cov ntaub ntawv aggregation")Hais txog txoj kev kuaj dej
