WHAT THE TEST MEASURES

Sans AU Quiz - Description and methodology of the test

Fans who use fictional characters as mirrors for everyday preferences can use the Sans AU Quiz to compare five recognizable interpretations through choices about friendship, creativity, boundaries, conflict, and group life. The result offers a playful profile of current affinities, helping readers reflect on the reactions and social styles they notice in themselves. It suits anyone wanting a Sans quiz focused on AU character preferences.

What This Assessment Explores

These outcomes show affinities involving energy, efficiency, creativity, trust, boundaries, loyalty, and uncertainty. Situations cover friendship, planning, conflict, community, and setbacks. It works as a quiz about which Sans you are, showing whether one style stands out or several are close.

The five scales are:

  • Classic Sans (0-12) shows relaxed wit, efficiency, and loyalty; bands: Different wavelength (0-4), Familiar resonance (5-8), Strong affinity (9-12).
  • Error Sans (0-12) shows autonomy, distance, and boundaries; bands: Different wavelength (0-4), Independent streak (5-8), Strong affinity (9-12).
  • Ink Sans (0-12) shows creative exploration and shifting perspectives; bands: Different wavelength (0-4), Creative resonance (5-8), Strong affinity (9-12).
  • Underfell Sans (0-12) shows guarded trust, bluntness, and loyalty; bands: Different wavelength (0-4), Familiar edge (5-8), Strong affinity (9-12).
  • Underswap Sans (0-12) shows enthusiasm, persistence, and sociability; bands: Different wavelength (0-4), Upbeat connection (5-8), Strong affinity (9-12).

Methodology and Evidence Base

Each prompt presents a social or creative situation with four possible reactions. This forced-choice self-report asks respondents to select the closest option rather than rate agreement. Themes include encouragement, planning, improvisation, privacy, conflict, community, and setbacks.

The result displays and compares five outcome scores; the highest marks the strongest affinity, and scores within one point of it form a blended result. As a quiz covering Sans AUs, it compares the patterns represented by the outcomes.

Studies by Elvery on parasocial connection, Newcombe on fanon legitimacy, and Nguyen, Khadadeh, and Jeong on fictional-character identification offer context only. They do not validate the five Sans affinity scales or online scoring, and this questionnaire is not presented as an adaptation of those works.

Undertale, created by Toby Fox, supports the canonical Sans reference; the other four outcomes are AU interpretations rather than characters from that game. This quiz about what Sans AU you are describes an affinity, not a permanent identity. Mood, fandom familiarity, relationships, self-awareness, and response bias can affect answers, so close scores are best read as a blended snapshot.
