Cialdini, koji je vršio mnogo istraživanja da bi bolje shvatio način na koji razmišljaju oni koji razbacuju smeće, kaže za Southeast European Times, "Naša istraživanja ukazuju na to kako je manje vjerovatno da će ljudi razbacivati smeće u čistoj, nego u zaprljanoj sredini."
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."
