Personality, self-knowledge, and meat reduction intentions.

Area of Science:

• Psychology
• Environmental Studies
• Animal Welfare

Background:

• Meat consumption poses significant ethical and environmental concerns.
• Existing interventions for meat reduction have shown limited effectiveness.
• Factors influencing intentions to reduce meat consumption are not well understood.

Purpose of the Study:

• To investigate the role of personality traits in predicting intentions to reduce meat consumption.
• To assess the impact of self-knowledge interventions on meat reduction intentions.
• To identify key psychological predictors of meat reduction intentions.

Main Methods:

• Three preregistered studies were conducted.
• Brief interventions aimed at encouraging meat reduction were tested.
• Personality traits were examined as predictors of meat reduction intentions.

Main Results:

• No significant effect of brief interventions, with or without self-knowledge components, on meat reduction intentions was found.
• Small but robust associations were observed between intending to reduce meat consumption and high Openness to Experience.
• High Emotionality and the perception of meat reduction as a moral behavior were also associated with intentions to eat less meat.

Conclusions:

• Individual differences, particularly personality traits, appear to be more influential in predicting meat reduction intentions than brief interventions.
• The findings suggest that focusing on individual psychological factors may be more effective for promoting meat reduction.
• Implications for developing targeted strategies to encourage sustainable dietary changes are discussed.
