What these studies show is that when people are asked to give reasons for their preferences, they may struggle to find the words. Sometimes aspects of their reaction that are not the most important determinants of their overall feeling are nonetheless easiest to verbalize.
The studies discussed highlight a common phenomenon where individuals have difficulty articulating the reasons behind their preferences. When prompted to explain why they favor one option over another, they often focus on superficial details rather than the underlying factors that truly influence their choices.
This tendency suggests that what people can easily express might not accurately reflect the most significant aspects of their decision-making process. Consequently, their verbalized reasons may overlook the deeper motivations that play a crucial role in their feelings and choices, as explored in Barry Schwartz's "The Paradox of Choice: Why More Is Less."
