Fighting Against Uncertainty With Reason.

We make decisions every day, many of which are so straightforward that we hardly notice we are making them. But we tend to struggle when uncertainty is a probability.

Humans generally use two decision-making strategies when faced with uncertainty: exploitation and exploration. Exploitation involves frequently choosing options that are familiar and provide a higher certainty of reward. Exploration involves trying out choices that are unfamiliar. In an uncertain and changing environment, it is thought that the best strategy is to flexibly alternate between exploration and exploitation.
