Questions & Answers

Q: Why do we disagree on scientific consensus?

Disagreement stems from filtering scientific information through our prior beliefs, values, and ideologies. People assimilate reality into their biased worldview rather than adjusting their worldview based on reality. Strongly held identities also play a significant role in protecting personal beliefs.

Q: Why is there opposition to HPV vaccine mandates?

Opposition arises from differing views on the vaccine's impact on sexual behavior. While some see it solely as a protective measure against cancer, others view it as potentially promoting promiscuity among minors or certain demographics.

Q: How does the perception of risk differ based on worldview?

Cultural cognition and motivated reasoning influence risk assessment. Individuals with hierarchical and individualist worldviews may be skeptical of climate change or the need for certain vaccines, while those with egalitarian and communitarian views prioritize societal goals and protecting their children from diseases.

Q: How does scientific literacy impact belief persistence?

Ironically, the more scientifically literate individuals are, the more likely they are to stick to their existing beliefs. This is because we tend to protect our identities and avoid having facts challenge our deeply held truths.

Summary & Key Takeaways

• Despite scientific consensus, public agreement on issues like climate change, HPV vaccines, and nuclear waste disposal is elusive due to filtering information through personal beliefs and values.

• Compliance for mandatory vaccinations is high, but HPV vaccine mandates face opposition due to differing views on its impact on sexual behavior.

• The way people process new information is influenced by pre-existing mental shelves, categorizing new facts based on their alignment with personal beliefs and values.
