Under which conditions does collective intelligence provide accurate decision-making support for complex problems and when does it fail? Concepts of collective intelligence (aka the “wisdom of crowds”) play increasingly fundamental roles in understanding and modelling complex reasoning and evaluation scenarios. We look at the networks behind opinion formation, the impact of network embeddedness and diversity on collective intelligence, and how to support collective reasoning and collective intelligence in online platforms.
Current projects include:
- We investigated the role of networks in launching successful crowdfunding campaigns.
- We demonstrated cultural and economic biases in funding decisions—a finding that contradicts the flat-world hypothesis, i.e., the idea that globalization eventually leads to economic equality.
