How to choose a social psychology dissertation topic (UK 2026)

Three practical filters. One: the replication crisis has reshaped what passes in social psychology — examiners reward pre-registered, adequately powered designs. Budget for minimum 80–150 participants per condition for a medium effect. Two: sensitive topics (prejudice, political attitudes, intergroup conflict) need stronger BPS ethics justification; you’ll usually need debriefing scripts and participant-support signposting. Three: online paradigms (vignette studies, IAT via Project Implicit, attitude surveys) are faster to approve than lab-based behavioural studies. Every cluster below flags the realistic design type.
