How do we You are entitled to your own study human opinion, but not your own facts. development? ~ Daniel Moynihan A lot of ideas “seem” true! Ex. Crime rates have increased How can Ex. Vaccines cause autism Ex. Hydroxychloroquine cures COVID we Can’t we base understanding on know INTUITION? Some things “feel” true because they feel familiar what is Ex. “Use only use 10% of our brain?” (wrong!) TRUE? Ex. Opposites attract! (wrong) Big Problem: We’re BIASED for a good reason! Evolutionary advantage: being biased We humans has kept us alive for thousands of years are BIASED! 1. Confirmation Bias Two We seek information that confirms our existing beliefs Important Ex. Social media echo chambers Ex. Getting your news from very slanted sources Human Biases 2. Pattern detection in random events We like order – makes sense of chaotic world But sometimes we sees patterns where there are none https://youtu.be/z98U1nMFrJQ Just as we seek to be “right” and search for information to prove we were correct. “Science” does everything possible to Science prove itself WRONG! It’s like if “science” were a person, it’d be telling itself ”I’m sure I’m counters wrong, but how am I wrong?” our Imagine a person desperate to find their flaws. biases! https://youtu.be/8MqTOEospfo How Does Science Try to Disprove Itself? Start with a THEORY HYPOTHESES allow us to test our theory: predictions that force us to try to FALSIFY our hypotheses (“I can’t be right, tell me I’m wrong”) Research helps us improve on our FACTS over time (we build on facts to understand complexity better) REPLICATION helps catch biases that slip through Research Methods Descriptive Correlational Experimental Cross-Sectional Researchin g Developm Longitudinal ent Sequential Cross-sectional versus Longitudinal Research Design Sequential Research Design No Harm Informed Consent Ethics in Confidentiality Research Deception Debriefing
