Many of us regularly make aesthetic choices. We buy paintings, music, and novels; we visit concerts and galleries. Aesthetic buying refers to buying things just because they are pleasing to the eye, not for their utility. Visually appealing products stimulate the brain’s reward system, triggering dopamine and offering instant gratification. Buying things that look good becomes emotionally satisfying, even if they serve no real purpose.

The buying decision process, in general, involves the interaction of two distinct decision systems (often in conflict with each other): a deliberative system (analytic thinking) and an automatic (impulsive) system. To make good choices, the two systems must work well together to support a person’s actual goals.

When we are calm, the deliberative system guides slow, rational thinking. The impulsive system acts spontaneously without consideration for the broader consequences of the action. The impulsive system is heavily biased toward the present (clicking “Buy Now”). The final decision is based on the relative strength of the impulsive system and the deliberative system.

Aesthetic preference can also be the product of two distinct processes that differ fundamentally in the way the perceive engages in the processing of the stimulus: gut feeling and aesthetic elaboration (Graf & Landwehr, 2017). People may process aesthetic stimuli not only passively but also actively and elaborately, like when a customer evaluates the interior as well as exterior designs of a car.

In other words, when people encounter an object (cars, bikes, chairs, or iPhones), they can pass an aesthetic judgement spontaneously and quickly, or they can process the object more extensively, which includes reflection and elaboration, before they evaluate it aesthetically. Aesthetic judgements are likely to be qualitatively different depending on which approach is used.

The Clash Between Beauty and Function

Aesthetic choices are based on a trade-off (a battle) between beauty and usefulness. For example, when people approach a car in a showroom or see a new car model in a magazine, their first response will be one of visual attractiveness: “Does this car appeal to me?” But we are also reluctant to spend on such items and tend toward those that appear, above all, to be practical (useful). In this case, the reflective system exerts control over the impulsive system to suppress the urges.

Our attitude formation is often prompted by visual appeal or visual aesthetics. Instinctively, we reach out for attractive things. The human brain processes visual information remarkably quickly. For example, research shows consumers can form opinions about websites within 50 milliseconds of visual exposure (Schlamann, 2026). This rapid assessment determines whether potential customers feel drawn in or deterred before they have consciously evaluated features or benefits.

Product aesthetics create powerful first impressions that influence purchasing decisions through emotional connection rather than rational analysis. When products are visually appealing, consumers perceive them as higher quality, more valuable, and more trustworthy. This explains why well-designed products often command premium pricing even when their functional capabilities match lower-priced alternatives.

Why Simplicity Wins the Sale

In contrast, the deliberative system is typically effortful. This may explain why responses to artwork vary as a function of expertise (their brains decode complex artwork effortlessly). That is why people prefer things that are easy to process; it helps them to allocate limited mental resources in a world with high demand on their attention. The ease of processing (known as cognitive fluency) makes things familiar and is associated with positive evaluations.

In sum, aesthetic judgements critically depend on the perceives processing style that interacts with the ease or difficulty of stimulus processing. The aesthetic judgement determines the purchase of expensive items (e.g., furniture), implying that people are likely to have a greater need to think more deeply when encountering aesthetic products.
