Though the Science study’s authors cautioned against an overly broad interpretation of their findings, the results suggest that fear leads to political conservatism.

"Threatening situations do indeed seem to increase people’s affinity for politically conservative opinions, leaders, and parties," said New
York University psychologist John Jost.

Study co-author Kevin Smith, also a University of Nebraska political scientist, demurred at making such a connection. "Historically speaking, politicians have appealed to the ‘be afraid’ response in the electorate in an attempt to mine votes," he said. "But in terms of going from campaigning to what we did in the laboratory, that’s a large leap."

But even Smith agreed that "people with stronger responses are more sensitive to potential threats in their environment."

Asked whether the findings imply a fearmongering strategy for conservatives, New York University psychologist David Amodio responded, "Yes.
And some people believe that they are actively using this strategy."

The Bush administration has been accused of exploiting fears, though it’s hardly a new approach.

"The whole aim of practical politics," wrote journalist gadfly H.L. Mencken,
"is to keep the populace alarmed (and hence clamorous to be led to safety) by menacing it with an endless series of hobgoblins."

Jost condemned such tactics. "From an ethical standpoint, conservative campaigns should not exploit feelings of fear in the general population," he said.

Of course, ethics tend to be forgotten during election seasons.
