The reasons why the ice bucket challenge is so successful
1. It’s for a good cause (sure but so is every charity right?)
2. It allows individuals to invite others and we actually want to, unlike a chain letter (we all want to project a good impression so we pass on the challenge)
3. We see others doing it (social proof)
I’m sure most people that took the ice-bucket challenge didn’t know what ALS stood for but thanks to this excellent viral campaign they’ve reached millions of people but on an individual level. It’s a good model to follow, expect to see more of it.
