In the United States, over 30% of individuals eligible for public welfare programs do not utilize the benefits, largely due to misperceptions about public stigma. Research indicates that people often underestimate their own positive attitudes toward welfare-eligible individuals compared to what they believe others think. Studies reveal that when participants learn someone is eligible for Supplemental Nutrition Assistance Program (SNAP) benefits, they experience various reactions, including stigma and negativity, but believe their attitudes are more favorable than those of their peers and the public. Subsequent studies show that perceived public stigma can negatively influence individuals’ intentions to apply for SNAP or to recommend it to others. An intervention aimed at reducing perceived stigma among SNAP-eligible individuals showed some effectiveness, but not enough to significantly increase application or referral rates for the program. The findings highlight the role of perceived stigma in welfare participation and suggest that addressing these misperceptions may encourage more eligible individuals to access benefits.
