Users frequently base their evaluation of design proposals on emotional appeal and desirability, even when they cannot articulate the specific reasons for their preferences. This user-centred design research insight is drawn from a 2021 study published in Proceedings of the Design Society. Using Qualitative and quantitative analysis, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize understanding and designing for emotional appeal alongside functional performance, as this is a primary driver of user acceptance.

Emotional Appeal Significantly Influences Design Proposal Evaluation, Often Without Explicit Rationale

Users frequently base their evaluation of design proposals on emotional appeal and desirability, even when they cannot articulate the specific reasons for their preferences.

Key Findings

  • 01Users often make judgments about design proposals based on implicit emotional responses.
  • 02Stated rationales for design preferences do not always align with the actual rankings provided.
  • 03The criteria for evaluating design proposals can be complex and not easily articulated.
02

Application

Design takeaway

Prioritize understanding and designing for emotional appeal alongside functional performance, as this is a primary driver of user acceptance.

How to apply

When testing design concepts, use a combination of ranking tasks, observational methods, and open-ended questions that encourage users to express feelings and intuitions, not just logical reasons.

Project actions

  • 01When testing your designs, ask users to rank them and then talk about their feelings and initial reactions, not just what they think is 'good' or 'bad' functionally.
  • 02Observe user behaviour and body language during evaluations, as this can reveal emotional responses that aren't spoken.
03

Method & Evidence

AimTo investigate how users evaluate design proposals, focusing on the interplay between emotional responses and stated rationale.
MethodQualitative and Quantitative Analysis
ProcedureParticipants were asked to rank a series of design proposals and provide commentary on their rankings. Their verbalized reasoning was recorded and analyzed in conjunction with their ranking decisions.
ContextProduct Design Evaluation

Variables

IVDesign proposals (varying in aesthetic and emotional appeal)
DVUser rankings of design proposals, user commentary/rationale
CVType of design proposals presented, instructions given to participants
04

Strengths & Limitations

Strengths

  • +Investigates the often-unspoken emotional dimension of design evaluation.
  • +Highlights a potential disconnect between user perception and articulation.

Limitations

It can be difficult to accurately measure or quantify emotional responses. Users may not be fully aware of their own emotional drivers.

Reliability & validity

Reliability could be improved by using a larger sample size and more standardized questioning. Validity is supported by the observation of a discrepancy between stated reasons and actions, suggesting it captures a real phenomenon.

Think critically

If users' stated rationales don't always match their rankings, how can designers reliably use user feedback to improve designs, and what methods are best for uncovering the true drivers of preference?

05

Design Principles

"Design for emotional resonance; user preferences are often driven by affective responses that may not be consciously articulated."

This highlights a critical gap between a product's functional requirements and its market success. Designers must consider the affective dimensions of user experience, as these often drive purchasing decisions more than purely technical specifications.

06

What This Means for Your Design

People often decide if they like a design based on how it makes them feel, but they might not be able to explain why, and sometimes they say one thing but their actions (like ranking) show another.

How to use in your project

  • 1.This research can inform the user testing phase of your design project, showing why it's important to look beyond surface-level feedback.
  • 2.Use the findings to justify the methods you choose for gathering user feedback, especially when exploring subjective qualities.

Quick Cite

Paragraph starter

This study highlights that user evaluations of design proposals are significantly influenced by emotional appeal and desirability, often without users being able to articulate explicit justifications. This suggests that design practice must incorporate methods to capture and respond to these affective responses, as they play a crucial role in user acceptance and market success, even when not consciously recognized by the user.
