Time Biases

Time Biases argues that rationality requires temporal neutrality: we should not discount future or past events based on their timing.

Meghan Sullivan uses real-life planning puzzles—such as retirement savings, compensation for injuries, and attitudes toward death or climate change—to show why time biases are irrational.

Drawing from philosophy, psychology, and economics, she develops a theory of personal persistence over time and explains the origins of these biases through an evolved emotional heuristic model.
