NPR’s Morning Edition and the Sunlight Foundation suggest that congressional speech-making is becoming less sophisticated. The presentation appears to validate conventional wisdom that American politics has taken an anti-intellectual turn of late, but the story shows flawed methods coupled with confirmation bias.
“Socialism” and “liberalism” are poorly defined in US politics; the former is over-applied to left-of-center positions, and the latter used in two almost reverse ways. “Neoliberalism” is a hot topic in contemporary anthropology, but the word is sometimes used without sufficient reflection. One way to spot the best work is to look for authors who take pains to define the terms.
