PSYCH 120A Chapter Notes - Chapter 12.3: Belief Bias, Confirmation Bias, Syllogism
Document Summary
Induction: process through which you make forecasts about new cases based on clues you"ve observed so far. Deduction: start with claims or assertions that are given and ask what follows from these premises. Tendency to be more responsive to evidence that confirms your beliefs rather than to evidence that might challenge your beliefs. Likely to take evidence that confirms beliefs at face values. When faced with disconfirming evidence, people are skeptical and scrutinize the new evidence for flaws/ambiguities. People may not use disconfirming evidence even when it is undeniable. Selective search of evidence in memory biased towards confirming belief. Categorical syllogisms: logical argument that begins with two assertions (premises) each containing a statement about a category. Completed with a conclusion that may or may not follow from premises. Valid syllogisms: conclusion does follow from premises stated. All p are m. all s are m. therefore, all s are p.
