How does clinical evidence work?

Ben Goldacre's Moment of Genius on BBC4 radio:

"Clinical trials in medicine are designed to be free from bias. They test, as objectively as possible, the effectiveness of a particular intervention.

When you bring the results of all these individual trials together, however, how do you weigh up what evidence is relevant and what is not? In 1993, a method of "systematic review" was introduced that enables us to get the clearest possible view of the evidence."

"Europeans Work to Live and Americans Live to Work" But Who is Happier?

Americans work 50% more than the Germans, the French and the Italians. Americans may work more than Europeans because of domestic tax rates - there are lower tax rates in the US than in Europe, and hence working more pays off more in the US. In other words, working longer hours pays off more in the US than in Europe.

This study compares the working hours and life satisfaction of Americans and Europeans using the World Values Survey, Eurobarometer and General Social Survey.

The purpose is to explore the relationship between working hours and happiness in Europe and America. Is it possible that working more makes Americans happier than Europeans?

The findings suggest that Americans may be happier working more because they believe more than Europeans do that hard work is associated with success.
