Fish Story: Animals Adjust Reactions to Misinformation

Coral reef fish.

Said Cornell's Andrew Hein, "We believe this form of dynamic control of sensitivity may be widespread in biological systems."


A multi-institutional team of scientists found fish can reduce the risk of overreacting to misinformation by adjusting their sensitivity to the actions of others.

The researchers analyzed underwater footage of events that startled foraging coral reef fish in Mo'orea, French Polynesia, using new computer vision tools, machine learning, and computational simulation.

Using computer vision technology to analyze footage of the fish from underwater observatories in coral reefs, the researchers precisely tracked the actions of every individual in a frame and reconstructed what each individual saw and the decisions they made.

Said Cornell University's Andrew Hein, "When we took our new model, and we applied it to our data, we found that it explains the data beautifully, and appears to be very consistent with what the animals are actually doing."
