Wild Fish Reveal Two Distinct Cognitive Styles in Decision-Making
Key Takeaways
- Researchers conducted over 5,000 underwater trials on two species of featherfin cichlids in Lake Tanganyika.
- When decisions were simple, both species behaved identically; when complex, one species was fast and decisive, the other slow and integrative.
- The findings parallel Daniel Kahneman's 'Thinking, Fast and Slow' dual-process theory of human cognition.
- The study suggests evolution can shape not only what animals choose but how they make decisions.
