Psychology Personal Statementfor Oxford & Cambridge

A college enrichment session on research methods led me to the 2015 Science paper "Estimating the reproducibility of psychological science". The detail that stayed with me was that only 36 of 100 replication attempts produced statistically significant results. That made psychology more interesting. It suggested that behaviour is shaped not only by what people do, but by how researchers define, measure and interpret what they see. Since then, I have become interested in how psychology can make strong claims about behaviour without pretending that people are easier to study than they really are. That is what draws me to the subject. I am especially interested in social psychology and research methods, particularly how claims about authority, identity and distress can be made rigorous without ignoring the contexts that give them meaning.

My qualifications have helped most when they have made me slow down and ask what a study can really show. During A level psychology, social influence was the topic that pushed me furthest in that direction. Milgram's obedience experiments are often presented as if they explain why ordinary people comply with authority, yet I found the procedure as important as the result. The laboratory gave Milgram control, but it also raised questions about what participants believed was happening and how far obedience there resembled obedience in everyday life. Studying the topic made me realise that evaluation is not an extra paragraph added at the end of psychology; it is part of the subject's thinking. My EPQ developed that idea into a longer investigation. I asked how far classic social psychology experiments could explain behaviour outside the laboratory, using Milgram, Rosenhan's "On Being Sane in Insane Places", the BBC Prison Study and the 2015 reproducibility paper as core sources. To stop myself making loose comparisons, I built a table for sample selection, operational definitions, ecological validity and whether later work counted as direct or conceptual replication. The hardest part was abandoning my original plan to sort studies into reliable and unreliable. That binary collapsed once I compared what each study was actually trying to show. A tightly controlled experiment could support only a narrow claim, while a historically specific study could still reveal something important even if it resisted exact replication. Writing the project taught me that methodological criticism is part of how psychology thinks.
