The Scenаriо: "Mаrcus is а university student whо recently jоined an environmental activism group on campus. Initially, he joined simply because he wanted to meet new people. However, after attending several intense weekly meetings where the members discussed the climate crisis, Marcus found that his views became much stronger than they were before. He now refuses to buy products from companies the group dislikes and feels a strong sense of pride when wearing the group’s logo. Recently, he felt a deep sense of guilt when he realized he still owned a pair of shoes from a 'blacklisted' brand, leading him to immediately donate them and buy a sustainable pair instead." The Question: On Group Polarization: Explain how group polarization could account for Marcus’s views becoming "much stronger" after attending the weekly meetings.
