We laten die culturele achtergrond trouwens méér mee-spelen dan het feit of de expert onze mening al dan niet deelt.
Dit blijkt uit een onderzoek over hoe het komt dat er zoveel mensen zich verzetten tegen het HPV-vaccin (vaccin tegen baarmoederhalskanker).
We zorgen er dus best voor dat er experten zijn met verschillende culturele achtergronden én dat er minstens een expert is met dezelfde culturele achtergrond als de populatie die we willen bereiken...

A new study concludes that people tend to match their risk perceptions about policy issues with their cultural values, which may explain the intense disagreement about proposals to vaccinate elementary-school girls against human-papillomavirus (HPV). The study also says people's values shape their perceptions of expert opinion on the vaccine.
HPV is a widespread disease that, when sexually transmitted, can cause cervical cancer. In October of 2009, the Center for Disease Control and Prevention (CDC) recommended that the vaccine be given to all girls ages 11 or 12. However, the recommendation has been mired in controversy, and so far adopted in only one state and the District of Columbia.
An online experiment involving more than 1,500 U.S. adults reveals that individuals who have cultural values that favor authority and individualism perceive the vaccine as risky, in part because they believe it will lead girls to engage in unsafe sex. But individuals with cultural values that favor gender equality and pro-community/government involvement in basic health care are more likely to see the vaccine as low risk and high benefit.
When views about HPV vaccines came from sources respondents believed shared their values, individuals tended to be more willing to accept the information. But when it came from an expert whom they perceived held values different from theirs, the information was not accepted. In the first instance, respondents perceived the experts to have cultural credibility and trustworthiness, but when respondent values differed from the experts, the experts were perceived to lack cultural credibility.
Nevertheless, when experts who held pro-authority and individualistic values asserted that the vaccine was safe, and experts perceived as holding egalitarian and pro-community values argued it was risky, subjects with those values tended to moderate their original viewpoints and give consideration to an opposing viewpoint, because the information came from someone they perceived shared their values.
The study is the most recent in a series researchers have conducted with NSF support to test the "cultural cognition thesis:" the idea that because individuals can't easily judge risks when it comes to evaluating complicated or disputed policy issues, they rely on beliefs grounded in cultural ideology to help them.
"The result suggests that the identity of the source is a more important cognitive cue than how people feel about the information alone," said Kahan.
The researchers suggest that anyone who has a stake in promoting informed public debate make an effort to recruit information providers that have diverse cultural outlooks and styles. The key, they say, is to avoid creating or reinforcing any impression--even a tacit one--that a scientific debate over policy is an "us versus them" dispute.
