SPEAKER: Dr. Elias Thorne, Professor of Cognitive Sociology, London School of Economics. Recorded lecture delivered at the British Academy Annual Symposium. Good evening. What I intend to examine today is a phenomenon that sits at the intersection of psychology, history, and urban design: how societies construct, maintain, and occasionally dismantle their collective memories. [pause] Let us begin by dismantling a persistent metaphor. For decades, both popular discourse and early cognitive science treated memory as a kind of archival repository — a mental library where experiences are stored intact and retrieved unchanged. Contemporary research has thoroughly dismantled this notion. We now understand that remembering is not an act of retrieval but an act of reconstruction. Each time we recall an event, we are not playing back a recording; we are reassembling fragments influenced by our current emotional state, subsequent experiences, and, crucially, the narratives circulating within our social group. The implication for collective memory is profound: what a society remembers is less a historical record than a continuously negotiated present-day consensus. [pause] This brings me to what I term the institutional friction problem. Governments and cultural foundations invest heavily in monuments, museums, and official archives, operating under the assumption that physical permanence guarantees cultural retention. Yet my fieldwork across post-industrial European cities reveals a consistent pattern: when institutional narratives diverge too sharply from lived community experience, the public does not merely ignore these structures; they actively reinterpret or subvert them. The bronze statues intended to cement a heroic national narrative frequently become canvases for protest art or sites of ironic pilgrimage. The lesson here is that commemorative architecture cannot impose memory; it can only offer a stage upon which memory is performed, and if the script feels inauthentic, the audience will rewrite it. [pause] The digital era has introduced a complication that previous generations of sociologists could scarcely have anticipated: algorithmic fragmentation. Social media platforms are often celebrated as democratising forces that give voice to marginalised histories. While partially true, this overlooks the structural reality of engagement-driven curation. Algorithms prioritise content that triggers high-arousal emotions — outrage, nostalgia, or moral indignation — which means that collective memory online becomes increasingly polarised and episodic. We are witnessing the erosion of shared chronological frameworks, replaced by what I call affective silos: parallel memory ecosystems where different groups inhabit entirely different historical timelines, reinforced by personalised feeds. The danger is not forgetting, but remembering selectively in ways that preclude mutual understanding. [pause] I want to turn briefly to the role of ritual, an area where traditional practices offer insights that digital platforms consistently fail to replicate. Annual commemorations, whether solemn vigils or civic parades, function not merely as reminders but as synchronising mechanisms. The physical co-presence of participants, the shared acoustic environment, and the repetitive choreography of ceremony generate what sociologists call collective effervescence — a temporary dissolution of individual boundaries that reinforces group cohesion. Crucially, these rituals are most effective when they incorporate spaces for ambiguity and grief, rather than forcing premature closure. Memorials that demand unquestioning reverence tend to breed resentment; those that invite reflection and even discomfort foster genuine intergenerational transmission. [pause] Finally, let me address the methodological shift required for researchers in this field. We have long relied on surveys and archival analysis to gauge what populations remember. These tools are necessary but fundamentally static. They capture stated beliefs at a single moment, missing the dynamic, conversational nature of memory formation. The approach I now advocate is what I term longitudinal narrative mapping: tracking how stories about pivotal events mutate across family conversations, local media, and educational curricula over decades. This reveals not what people remember, but how they remember — the omissions, the embellishments, the strategic silences that ultimately shape a society's identity. Memory, in the end, is not a vault to be unlocked, but a dialogue to be sustained.
