This is not to say that intrasexual competition entirely prevents preference evolution; simulation results indicated that preferences may still evolve if they are sufficiently strong enough to overcome natural selection, and that the multiple preferences evolving simultaneously may reduce (but not eliminate) direct selection.
One possibility is that multiple preferences may aid in alleviating or preventing competition.
When multiple preference orders are involved, the sequence of implementation may affect the selection, so preferences for the most important aspects, usually concerning smoking, are implemented first.
Some investigators have excluded the responses of individuals who did not appear to understand the preference testing process [ 13, 39, 40], and others have developed techniques to detect and minimize inconsistencies during multiple preference measurements in the same subject [ 41].
It's called the "multiple liquidation preference problem" and I've written about it in the "Pommardify" case study mentioned above.
In this study, we extend the QFD methodology by introducing a new group decision making approach that takes into account multiple preference formats and fusing different expressions into one uniform group decision by means of fuzzy set theory.
In this study, a new fuzzy group decision-making approach is presented to fuse multiple preference styles to respond CNs in product development with QFD in a better way.
Few studies tested whether using multiple preference assessment methods, such as both conjoint analysis and time tradeoff methods, would result in different patient choices.
To make realistic predictions about the evolution of multiple preferences I used simulation models to explore when multiple preferences could evolve.
By examining both the evolution of condition allele with preference, and the introduction of preference into a high condition population, I can better distinguish the interaction between multiple preferences and condition evolution.
