Does the partisan divide extend to online reviews?

Liberals and conservatives differ starkly in their political convictions, and their assessment of social and economic issues. Surprisingly, they also write very different online reviews when they evaluate online purchases. Researchers analysed the web browsing behaviour of a sample of US consumers and found that liberal customers write online reviews that are longer and contain more arguments. Lorenz Graf-Vlachy explains the findings and examines the factors behind these behavioural differences.
