The Herd Instinct in U.S. Politics

Why did the GOP turn against stimulus? Ask a psychologist, by Ezra Klein.  (Washington Post, 9/6/2011)

Excerpt:   My favorite study [link here and screenshot of page 1 found below] in this space was by Yale’s Geoffrey Cohen. He had a control group of liberals and conservatives look at a generous welfare reform proposal and a harsh welfare reform proposal. As expected, liberals preferred the generous plan and conservatives favored the more stringent option. Then he had another group of liberals and conservatives look at the same plans, but this time, the plans were associated with parties.

Both liberals and conservatives followed their parties, even when their parties disagreed with their preferences.

The bottom line is this: Until quite recently, both parties supported the idea that you combat bad economies with stimulus spending. Now, during an extremely bad economy, the Republican Party has completely abandoned that position. That has left them without plausible solutions — the GOP talks now of things that have very little role in boosting short-term demand, such as deficit reduction and regulatory reform — and has left the Democrats without the votes to pass anything. And that’s left the country deep in the hole.
