Why it worked

The video uses relatable examples and clear explanations of a complex concept (the Volunteer's Dilemma) to engage the audience. The use of visuals and a narrative structure makes the information digestible and shareable.

Summary

The video explains the Volunteer's Dilemma using examples of the bystander effect and bacteria colony behavior. It highlights how the diffusion of responsibility in larger groups leads to inaction, even when a public good is at stake.

The Volunteer’s Dilemma is honestly a chilling concept from game theory, and the sad reality is that it makes sense when you think about it. It’s prevalent amongst people and even evolutionarily coded into bacteria. The idea that everyone suffers just because one person won’t make the sacrifice seems irrational, and yet this dilemma is found everywhere. As always I’d love to hear your thoughts in the comments, and follow for more game theory content! #gametheory #biology #bystandereffect #psychology #unedited (only OGs will know this is a repost)
