Spirals, a ubiquitous phenomenon in both nature and culture, have been crafted by humans as far back as 11,000 BC and have independently emerged in various locations. Their significance extends beyond mathematics and natural sciences, serving as popular motifs in art and design. Over time, a multitude of spiral types have been identified or invented, each with its unique aesthetic appeal. Despite the frequent assertion of their variation in beauty, empirical evidence to support such claims has been lacking. To address this gap, we conducted a study using various spirals - Archimedean, general Archimedean, logarithmic, golden, and Fibonacci - as stimuli in an online study. Each spiral type was represented in multiple versions, differing in size and number of loops. Participants were asked to rate the beauty of these spirals. The results revealed substantial differences in beauty among the spirals. Intriguingly, we identified two distinct groups of participants with contrasting preferences: one group favored Archimedean spirals and disliked logarithmic ones, while the preferences of the other group were reversed. Upon further analysis, we found that among the potential characteristics of the spirals - size, arc length, number of loops, and curvature - it was the arc length that was most influential in explaining the differences in preference.
