In April, we presented some initial findings from the project at the PSA annual conference in Oxford for a panel on the Politics of Age. We explore why some people become more right‑leaning as they age, and what a longitudinal lifecourse perspective can add to existing explanations of older people’s voting behaviour. Much research points to ageing effects, highlighting psychological change, stable values, and life‑cycle transitions such as work, family formation, and retirement. In Britain, Jane Green and Raluca L. Pahontu (2024) argue older voters’ greater wealth and lower debt levels gave them more economic security and self-insurance, which reduced risk aversion and helped explain their support for Brexit and in 2016. Older voters with wealth supported leave because they did not expect Brexit would impact their personal finances. The study highlights the importance of examining causal effects at the individual level, which is something we think we can add to with our study. Our paper argues for closer attention to individual‑level processes over time. Using a longitudinal lifecourse approach, we show how political change may reflect not only the accumulation of assets and security, but also the accumulation of stories, disappointments, and grievances. We illustrated this by tracing the political biography of one panellist who moves to the right as he grows older.
