The study also showed that, since we tend to favor what we consider first in a one-on-one comparison task, the order in which participants considered the two options was strongly influenced by the different labels. Republican respondents tended to evaluate the lower-priced item longer when the price difference was labeled a "tax", and in some cases, failed to consider the higher-priced item first even when instructed to.
The statistically significant difference would suggest that how we say things can affect not only a direct reaction to our words, but also the underlying evaluation process of our overall message. The researchers, David Hardisty and Weber, concluded:
What might seem like a trivial semantic difference to one person can have a large impact on someone else.I wonder if we will ever come to a day when people don't automatically dismiss "semantic differences" as "trivial".
