Welcome to the fourth episode of The Last Tuesday Project. Each month, this gaggle of rag-tag ruffians meet up to discuss one topic. Only one of us knows what that topic will be, and we get just one hour to research it. The outcome is a podcast full of laughs, stories, facts and tips on how to dig deeper.

This month, Alex, Hayley, Hannah, Shaun, and David veto a question on psychology and take a look at direct action activism. We talk about striking, Greenpeace, and the definition of "effective."
