Short answer

When designing product labels that convey multiple sustainability or health metrics, anticipate that these metrics may interact in consumers' minds, leading to unintended biases. Test combinations to ensure clear and accurate perception.

Presenting both nutritional and environmental scores simultaneously can lead consumers to misjudge the true healthiness and eco-friendliness of food products. This sustainability research insight is drawn from a 2024 study published in Food Quality and Preference. Using Experimental study with 1,061 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing product labels that convey multiple sustainability or health metrics, anticipate that these metrics may interact in consumers' minds, leading to unintended biases. Test combinations to ensure clear and accurate perception.

Dual Sustainability Labels Create Perceptual Biases in Food Choices

Presenting both nutritional and environmental scores simultaneously can lead consumers to misjudge the true healthiness and eco-friendliness of food products.

Food Quality and Preference · 2024

01

Key Findings

  • 01The Nutri-Score and Eco-Score significantly influence each other's perceived impact on consumers.
  • 02The combined presence of these labels can lead to biased assessments of a food product's healthiness and environmental friendliness.
02

Application

Design takeaway

When designing product labels that convey multiple sustainability or health metrics, anticipate that these metrics may interact in consumers' minds, leading to unintended biases. Test combinations to ensure clear and accurate perception.

How to apply

Before launching products with dual labeling systems, conduct user testing to assess how consumers interpret the combined information and whether any biases emerge.

Project actions

  • 01When researching user perception of product features, consider how multiple features might interact.
  • 02If your design involves multiple rating systems, plan to test for unintended consequences on user judgment.
03

Method & Evidence

AimTo investigate how the simultaneous presentation of nutritional and environmental scoring labels affects consumer perceptions of food healthiness and environmental impact.
MethodExperimental study
ProcedureParticipants were exposed to four food products with varying combinations of high/low Nutri-Score and Eco-Score ratings. Their perceived healthiness and environmental friendliness were then measured.
Sample1,061 participants
ContextFood product labeling and consumer perception

Variables

IV["Presence/absence of Nutri-Score","Presence/absence of Eco-Score","High/low rating on Nutri-Score","High/low rating on Eco-Score"]
DV["Perceived healthiness of food","Perceived environmental friendliness of food"]
CV["Type of food product","Participant demographics (potentially)"]

Strengths & Limitations

Strengths

  • +Large sample size enhances statistical power.
  • +Experimental design allows for causal inference regarding label effects.

Limitations

The specific food items used might not represent all food categories. The study's focus on German consumers may limit generalizability to other populations.

Reliability & validity

The study's between-subjects design and large sample size contribute to its reliability. Validity is supported by measuring direct perceptions of healthiness and environmental impact in response to controlled label variations.

Think critically

To what extent should designers aim for simplicity in labeling versus providing comprehensive information, given the potential for complex information to create unintended biases?

05

Design Principles

"Minimize perceptual bias in multi-attribute labeling by understanding and testing the interaction effects of different information cues."

Designers creating product labeling for food items need to be aware that the presence of multiple scoring systems can inadvertently influence consumer perception, potentially masking or exaggerating certain attributes. This understanding is crucial for transparent and effective communication in the food industry.

06

What This Means for Your Design

Putting two different scores on food (like how healthy it is and how good it is for the planet) can sometimes trick people into thinking it's better or worse than it really is, because the scores can mess with each other in their minds.

How to use in your project

Paragraph starter

The study by Jürkenbeck et al. (2024) highlights that presenting multiple sustainability labels, such as nutritional and environmental scores, can lead to significant perceptual biases in consumers. This suggests that designers must carefully consider the potential for interaction effects when developing product communication strategies, as the combined impact of labels may not always align with the intended message.
