Global warming: Undeniable evidence

The unwillingness of scientists at the University of East Anglia to release climate data to people who choose not to believe in climate change was a mistake. Science advances through openness, through the ability of others to replicate the same findings or demonstrate error in discovery and interpretation. Reluctance to disclose – revealed last week [...]

Mixed Impressions: How We Judge Others on Multiple Levels

We’ve all heard that people favor their own kind and discriminate against out-groups–but that’s a simplistic view of prejudice, says Amy Cuddy, a professor at Harvard Business School who studies how we judge others. In recent years she …
