About

LIME stands for Library of Interventions for Meat Elimination. In short, LIME is a continuously growing collection of all experimental studies that tested the effectiveness of a psychological intervention in reducing animal product consumption, improving attitudes towards animals, or changing related outcomes. This website was designed to make this literature more accessible to researchers, advocates, and policy makers.

At the core of LIME is a machine-readable, continuously growing database of intervention studies. For each study, we extracted information on the intervention mechanism (e.g., presenting facts, menu design) and content (e.g., animal welfare, the environment), the outcome measure (e.g., sales data, food diary), the participant sample (e.g., sample size, country), and much more.

This database can be accessed with the Data Explorer tool. You can explore the data with a customizable table that allows you to

• Select which of the many variables you want to inspect
• Include or exclude specific studies based on different criteria (e.g., only studies from a specific country)
• Download your customized database

The Meta-analysis tool allows you to synthesize the evidence across many studies. It allows you to:

• Specify which types of studies should be included in the analysis with the help of various filters
• Estimate the average effect size across the included studies
• Test for publication bias
