Crash Course: Navigating Digital Information - Lecture by John Green
Key Concepts
Importance of Evidence: Understanding that just as evidence is needed to support requests, such as a raise, evidence is also crucial in evaluating online information.
Reliable Sources: Trustworthy sources should provide convincing and solid evidence for their claims.
Evaluating Online Information
Three Key Questions: When encountering new online information, ask:
Who said that?
Why are they saying it?
What is the evidence?
Types of Evidence: Could include text, photos, videos, data, etc., as long as it supports a claim.
Factual vs. Opinion: Factual claims require proof; subjective opinions do not.
Misinformation & Disinformation: Claims without supporting evidence can lead to misinformation or disinformation.
Examples of Evidence Evaluation
Nathan Fielder's Tweet: Demonstrates a claim without supportive evidence.
Viral Facebook Post About Spider: Example of misinformation due to lack of credible evidence.
Senator Inhofe's Snowball: Shows irrelevant evidence used to argue against climate change.
Conspiracy Theories: Often lack credible evidence and rely on narratives that confirm biases.
Understanding Evidence Quality
Not All Evidence is Equal: The credibility of evidence depends on its source and relevance.
Spurious Correlation: Misleading connections between coincidentally linked events, e.g., movies by Nicolas Cage and drowning incidents.
Case of Vaccines & Autism: Example of a spurious correlation leading to public health consequences.
Strategies for Evaluating Evidence
Lateral Reading: Check multiple sources and verify evidence through reputable channels.
Ask Questions: Always question if the information makes sense and if it fits pre-existing biases.
Reliability and Relevance: Ensure evidence is both credible and directly supports the claim.
Conclusion
Decision Making: The quality of evidence affects the quality of decisions and outcomes, such as public health issues.
