I was very lucky that, when I worked for Oxfam and other big charities, I could read lots of big reports on what influenced politicians and businesses and the general public, what campaigns worked really well, which ones didn't.
Sono stata fortunata perché,  lavorando per Oxfam e altri grandi enti, ho potuto leggere lunghi resoconti su cosa influenzava politici, imprenditori e opinione pubblica, su quali campagne funzionavano  meglio e quali no.
