[SEJ] Joshua Becker: Does communication improve the wisdom of crowds?  It depends on the question.

esearch on the ‘wisdom of crowds’ has consistently shown that one way to improve the accuracy of numeric estimates such as economic forecasting is by using the average estimate of multiple individual contributors, rather than relying on one single person. However, decades of lab experiments have produced contradictory results about whether and when communication between group members makes the resulting average more accurate or less accurate. Thus despite the existence of over 100k results on Google scholar using the “Delphi method” form of information exchange, we lack clear evidence that this method is actually better than unstructured discussion, or that any form of communication is better than none. This talk will explain contradictions in prior research by showing how emergent network centralization interacts with pre-communication estimate distribution such that communication sometimes increases accuracy and sometimes decreases accuracy. Using a formal model of estimate formation and experimental data, I will argue that the fixed effect paradigm—i.e. the assumption that any form of communication is always either helpful or harmful—must be replaced with a model that depends on the particular estimation task under consideration. I will conclude by discussing some limitations of this model for describing true deliberation, sharing some new research under development, and opening the floor for collaborative speculation and brainstorming on how future research might address these topics.

TU Delft jointly wins XPRIZE Rainforest drone competition in Brazil

TU Delft jointly wins in the XPRIZE Rainforest competition in the Amazon, Brazil Imagine using rapid and autonomous robot technology for research into the green and humid lungs of our planet; our global rainforests. Drones that autonomously deploy eDNA samplers and canopy rafts uncover the rich biodiversity of these complex ecosystems while revealing the effects of human activity on nature and climate change. On November 15, 2024, after five years of intensive research and competition, the ETHBiodivX team, which included TU Delft Aerospace researchers Salua Hamaza and Georg Strunck, achieved an outstanding milestone: winning the XPRIZE Rainforest Bonus Prize for outstanding effort in co-developing inclusive technology for nature conservation. The goal: create automated technology and methods to gain near real-time insights about biodiversity – providing necessary data that can inform conservation action and policy, support sustainable bioeconomies, and empower Indigenous Peoples and local communities who are the primary protectors and knowledge holders of the planet’s tropical rainforests. The ETHBiodivX team, made of experts in Robotics, eDNA, and Data Insights, is tackling the massive challenge of automating and streamlining the way we monitor ecosystems. Leading the Robotics division, a collaboration between TU Delft’s Prof. Salua Hamaza, ETH Zurich’s Prof. Stefano Mintchev and Aarhus University’s Profs. Claus Melvad and Toke Thomas Høye, is developing cutting-edge robotic solutions to gather ecology and biology data autonomously. “We faced the immense challenge of deploying robots in the wild -- and not just any outdoor environment but one of the most demanding and uncharted: the wet rainforests. This required extraordinary efforts to ensure robustness and reliability, pushing the boundaries of what the hardware could achieve for autonomous data collection of images, sounds, and eDNA, in the Amazon” says prof. Hamaza. “Ultimately, this technology will be available to Indigenous communities as a tool to better understand the forest's ongoing changes in biodiversity, which provide essential resources as food and shelter to the locals.” . . . .
