Chronic self-doubters tend to be more materialistic, study shows

A new study found that people with enduring feelings of self-doubt scored higher on a measure of materialism. Chronic self-doubters believe that owning things proves their success. Materialism is a poor coping mechanism for uncertainty, linked to poor psychological functioning and lower life satisfaction.

City birds prefer rich neighbors

A study of 15 community parks found that bird diversity and abundance are linked to neighborhood income, not park size or vegetation. However, the correlation between trees and bird populations is weak, suggesting other factors, such as cat populations or urban planning, may be at play.
