It would be interesting to see the same study conducted on expert wine tasters. And to take the question even further, what would happen if these experts were told the prices, but THEN told that in some cases the lower priced wine was preferred by a majority of their fellow expert wine tasters? Would this color their thinking and alter the measured duration of pleasure center activation back in the OTHER direction?
As an audiophile, I try to look for high performance to price ratio. But the result of the experiment detailed above is something to keep in mind when deciding on purchases.
