A study is a weapon in an argument
Every study you learn should come with a purpose attached: which claim does it support, and which does it undermine? A study you can name but cannot deploy is worth one mark and no more — and one mark is not what the question is worth.
Learn each study with its weaknesses attached
- Sample. Undergraduates? Western? Male? Twelve people? This is where a great many evaluation marks live and they are free.
- Ecological validity. Does the lab task resemble anything a person actually does?
- Demand characteristics. Did the participants work out what was wanted and oblige?
- Does it replicate? Psychology has had a serious replication crisis, and engaging with it seriously is exactly the kind of thing that separates the top band. A famous study that failed to replicate is a *stronger* thing to write about, not a weaker one.
The debates are the structure
Nature/nurture, free will/determinism, reductionism/holism, individual/situational. These recur across every topic, and an answer that positions its evidence within a debate reads completely differently from one that lists findings. Learn the debates and the material stops being a pile of experiments and becomes an argument with sides.
