Which one do you prefer? 1.1.0

The tool "Which One Do You Prefer?" serves as an effective decision-making aid, particularly useful in scenarios that involve multiple options.

For instance, consider the dilemma of choosing a restaurant for dinner. The options include: 1) Italian cuisine, 2) a sushi bar, 3) a curry restaurant, or 4) dining at home (and facing the question of who will cook). Similarly, when contemplating the adoption of three cats from a selection of eight candidates, the decision-making process can become quite complex.

Many individuals may find themselves struggling to compare and rank various options according to personal preference. While instinctive methods like "eeny, meeny, miny, moe" may provide a quick solution, psychologists have developed a more structured approach known as the 'paired comparison' method. This technique simplifies the evaluation process by breaking down the simultaneous comparison into manageable pairwise comparisons.

Comparing just two candidates at a time is inherently less complex than evaluating many simultaneously. However, a notable limitation of this method lies in its requirement to assess all possible pairs in a round-robin format. For example, adopting eight cats necessitates 28 paired comparisons to generate a subjective ranking.

This application leverages the paired comparison method to reveal individual preferences across any category of items. Users can input details such as names, features, and photos for each candidate, enabling a systematic comparison that ultimately clarifies their subjective rankings.
