Cialdini, who has conducted a great deal of research to better understand the minds of litterbugs, told Southeast European Times, "Our research indicates that people are less likely to litter into a clean, than a littered environment."
Ćaldini, koji je sprovodio opsežno istraživanje da bi bolje shvatio svest onih koji razbacuju otpatke, izjavio je Southeast European Times-u: "Naše istraživanje pokazuje da je manja verovatnoća da će ljudi bacati otpatke u čistom okurženju nego u okruženju u kojem ima smeća".
