A new mathematical model published in the Review of Finance offers a formal account of something ancient in human experience: that we do not weigh all moments equally, and that this imbalance quietly reshapes our understanding of what is likely and what is not. Researchers show that when dramatic or extreme events command disproportionate attention, the resulting distortion of probability beliefs persists stubbornly across time — not as a correctable error, but as a structural feature of how selective minds learn.

Practical implications or real-world validation beyond theoretical model
Counterarguments or limitations of the research approach
Expert commentary from economists or behavioral scientists outside the research team
Discussion of how individuals or institutions currently address this bias
