Thinking like a psychologist
• You need to develop skepticism and critical thinking
• Separate uniformed opinions from examined conclusions
• Use scientific approach to come to conclusions about why people think, feel & act the way they do o People often overestimate their ability to describe, predict, & explain human behavior
- We consider ourselves experts on psychology
Hindsight bias
• Things that seem obvious to us after we’ve learned the outcome
• 911
False consensus effect
• A sense that everyone believes what we do when our exposure to the rest of the world is very limited and does not represent everyone
• People in Africa don’t share our beliefs and behaviors
Scientific method
• Used to AVOID BIAS in findings, to counter the effect it has on our thinking
• Describe, predict, explain
• Make observations → formulate theories to explain observation (must be testable) → propose hypothesis → specifies which result will support/reject theory

Why are the answers that flow from the scientific approach more reliable than those based on intuition and common sense?
- The answers that are found from the scientific approach are more reliable than those found through intuition and common sense because our thinking is usually clouded by bias and personal experiences and this often shows in our findings.
- Helps us distinguish reality & illusion
- There are limits to our common sense & intuition and we are easily misled in our findings
