rationalists
Reason over faith
Rationalists are people who emphasize reason and logic over emotion, tradition, or faith as the basis for knowledge and decision-making.
In philosophy, rationalism holds that some knowledge can be derived through reason alone, independent of sensory experience—contrasting with empiricism.
In contemporary usage, rationalists often identify with a community focused on cognitive biases, probability theory, and clear thinking: The rationalists debated whether AI posed an existential risk.
The term can carry either admiration or mild derision, depending on whether the speaker values or distrusts purely logical approaches to human problems.
