Traditional models underestimate extinction rates

...nore a critical parameter in projecting risk, they underestimate extinction rates. Standard models for predicting extinction assume that population growth and decline are governed by random, or stochastic, variables. But few scientists have actually tested the accuracy of these models with empirical data. To do t...

Men Estimate Men's Risks Of Common Disorders Higher Than Women Do, And Vice Versa

...on personal risk assessments suggest a tendency to underestimate one's own risk of illness compared to one's peers -- this is often referred to as optimism bias.
