A consumer's positive attitude towards reducing food waste, their belief in their ability to do so, and the influence of social norms are strong predictors of their intention to actually reduce waste. This sustainability research insight is drawn from a 2023 study published in Teoria e Prática em Administração. Using Meta-analysis with 30,960 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design interventions and products that not only inform but also empower consumers by addressing their attitudes, perceived abilities, and social influences regarding food waste reduction.
Psychological Drivers Significantly Increase Consumer Intent to Reduce Food Waste

Key Findings
- 01There is a consistent positive relationship between attitude and the intention to reduce food waste.
- 02There is a consistent positive relationship between perceived behavioral control and the intention to reduce food waste.
- 03There is a consistent positive relationship between subjective norms and the intention to reduce food waste.
- 04The effect size for subjective norms on intention is larger in samples of non-students.
Application
Design takeaway
Design interventions and products that not only inform but also empower consumers by addressing their attitudes, perceived abilities, and social influences regarding food waste reduction.
How to apply
When designing a product or service aimed at reducing food waste, consider how to positively shape user attitudes, enhance their sense of control over waste reduction, and tap into social norms that encourage this behavior.
Project actions
- 01Consider how your design can influence a user's attitude towards waste.
- 02Think about features that increase a user's confidence in their ability to reduce waste.
- 03Explore ways your design can leverage social proof or community norms.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Large aggregated sample size provides robust statistical power.
- +Meta-analysis addresses inconsistencies in previous research.
Limitations
The findings are based on intentions, which may not always translate into actual behavior. The specific context of the studies (e.g., student vs. non-student samples) can affect the results.
Reliability & validity
The meta-analysis increases reliability by averaging effects across studies. Validity is supported by the large sample size and consistent findings across multiple studies, though it relies on the validity of the original studies.
Think critically
While attitude, perceived control, and norms are important, what other factors might influence a consumer's actual behavior in reducing food waste, beyond their intention?
Design Principles
"Design for behavioral change by aligning product or service features with psychological motivators such as attitude, self-efficacy, and social influence."
Understanding these psychological drivers is crucial for designing effective interventions and products that encourage sustainable consumption behaviors. Designers can leverage these insights to create messaging, product features, and educational materials that resonate with consumers' motivations and perceived capabilities.
What This Means for Your Design
If you want people to waste less food, make them feel good about it, make it easy for them to do it, and show them that others are doing it too.
How to use in your project
- 1.Use this research to justify the psychological drivers you are targeting in your design.
- 2.Cite this study when discussing the importance of user attitudes, perceived control, and social norms in your design rationale.

Paragraph starter
This research indicates that consumer intention to reduce food waste is significantly influenced by their attitude towards waste reduction, their perceived behavioral control over waste reduction actions, and subjective social norms. Therefore, any design intervention aimed at reducing food waste should strategically address these psychological antecedents to maximize user engagement and behavioral change.
