Yacine is a first-year student. Every evening, he studies with his headphones on and his favourite songs playing. “Music helps me focus,” he says. His sister doesn’t agree. “Your grades went down since you started doing that. The music is distracting you.” They argue every night. Nobody knows who is right. Your team has been asked to find out — like real researchers. Over the next 5 sessions, you will find the papers, read them, write about them, and give Yacine an answer based on evidence, not opinions.
