Beware your information biases

kevin | Decision Making | Thursday, April 17th, 2008

Nicholas Kristoff makes some good points about some common decision traps in discussing the predictable reactions to the recent Obama / Clinton Debate.

To understand your feelings about Wednesday night’s debate, consider the Dartmouth-Princeton football game in 1951. That bitterly fought contest was the subject of a landmark study about how our biases shape our understanding of reality.

Psychologists showed a film clip of the football game to groups of students at each college and asked them to act as unbiased referees and note every instance of cheating. The results were striking. Each group, watching the same clip, was convinced that the other side had cheated worse — and this was not deliberate bias or just for show.

“Their eyes were taking in the same game, but their brains seemed to be processing the events in two distinct ways,” Farhad Manjoo writes in his terrific new book, “True Enough: Learning to Live in a Post-Fact Society.” It’s the best political book so far this year.

And this

We seek out information that reinforces our prejudices. One study presented listeners with static-filled recordings of speeches that they believed they were judging on persuasive power. Listeners could push a button to tweak the signal, reducing the static to make it easier to understand. When smokers heard a speech connecting tobacco with cancer, they didn’t try to improve the clarity to hear it more easily. But they pushed the button to get a clearer version of a speech saying that there was no link between smoking and cancer. Nonsmokers were the exact opposite.

This resistance to information that doesn’t mesh with our preconceived beliefs afflicts both liberals and conservatives, but a raft of studies shows that it is a particular problem with conservatives. For example, when voters receive mailings offering them free pamphlets on various political topics, liberals show some interest in getting conservative views. In contrast, conservatives seek only those pamphlets that echo their own views.

Likewise, liberal blogs overwhelmingly link to other liberal blogs or news sources. But with conservative blogs, the tendency is much more pronounced; it is almost a sealed universe.
