The Human Side of Misinformation Part 2 with Assoc. Prof. Marian-Andrei Rizoiu (445) [REPEAT]

In part two, Associate Professor Marian-Andrei Rizoiu from the University of Technology Sydney explains how misinformation and toxic online cultures spread. We dive into the "manosphere pipeline" targeting boys as young as 10, its real-world impacts on schools and families, and how it can escalate into radicalisation. Rizoiu outlines his team's six-stage pipeline - from passive curiosity to active involvement - and why simply giving people facts doesn't solve the problem. Instead, this is a human challenge, and his lab is exploring new ways to diffuse and counter online misinformation before it turns dangerous. Linkedin: Marian-Andrei Rizoiu
