We rely on the randomized activation of the heuristic of attribute substitution to analyze the effect of blood donation on donors' happiness. We randomly delivered two versions of a questionnaire where the happiness question is alternatively placed immediately before or after a categorical question asking about the blood donor condition of the respondent (non-donor, previously donor, donor). By comparing the answers given to the happiness question in the two versions, we find a positive effect of donating blood on donors' happiness. We discuss the pros and cons of this method to investigate the determinants of subjective well-being.
