The new leaded gasoline

John Burn-Murdoch for the FT on new polarization research:

Their key insights are that content relating to crime, immigration, race, gender and criticism of elites reliably increases viewing figures (while economics and healthcare cause people to switch away). This means there is a resulting shift in coverage towards more culture war issues and fewer socio-economic stories, which leads voters to rate these issues as more important. Politicians then respond by campaigning more on cultural hot button topics. All told, they estimate that the emergence and growth of cable news can account for fully one-third of the increase in US cultural conflict since 2000.

With any luck, we'll look back on this era and wonder why the hell we allowed this to happen.
