Debunking the Dunning-Kruger effect – the least skilled people know how much they don’t know, but everyone thinks they are better than average

The idea that the least skilled are the most unaware of their incompetency is pervasive in science and pop culture. But a new analysis of the data shows that the Dunning-Kruger effect may not be true.

Gain-of-function research is more than just tweaking risky viruses – it’s a routine and essential tool in all biology research

From cancer immunotherapy and antibiotics to GMO crops and pandemic surveillance, gain of function is a cornerstone of basic research.

Medicaid work requirements would leave more low-income people without health insurance – but this policy is unlikely to pass this time around

Adults insured by Medicaid who are 19 to 55 years old and don’t have children or other dependents would need to spend 80 hours a month doing paid work, job training or community service.
