Jamie is a Program Associate at Macroscopic Ventures, doing grantmaking focused on s-risks (suffering). In particular, reducing catastrophic AI misuse by malevolent or fanatical actors (e.g., via compute governance or infosec), conflict (e.g., cooperative AI) and improving AI welfare. Polaris’ focus areas include AI governance, digital sentience, plus reducing risks from fanatical ideologies and malevolent actors.
He also spend a few hours a week as a Fund Manager at the Effective Altruism Infrastructure Fund, which aims to increase the impact of projects that use the principles of effective altruism, by increasing their access to talent, capital, and knowledge.
Lastly, Jamie is President of Leaf, an independent nonprofit that supports exceptional teenagers to explore how they can best save lives, help others, or change the course of history. (Most of the hard work is being done by the wonderful Jonah Boucher though!)
Jamie previously worked as a teacher, as a researcher at the think tank Sentience Institute, and as co-founder and researcher at Animal Advocacy Careers, which helps people to maximise their positive impact for animals.
Social Movement Mobilization: Literature Review
Collective Identity and Community Building
Core concepts: Shared identity formation, in-group solidarity, boundary maintenance
Key findings:
Strong collective identities significantly predict sustained participation
Communities that balance inclusivity with distinctive identity markers show higher retention
Regular face-to-face interaction strengthens commitment beyond digital-only engagement
Evidence strength: Strong. Multiple longitudinal studies across diverse movements consistently show correlation between identity strength and participation persistence.
Notable research:
Polletta and Jasper’s (2001) review found identity processes central to all stages of activism
Snow and McAdam (2000) documented how “identity alignment” precedes sustained activism
Blee’s (2012) ethnographic studies showed how white supremacist groups use identity work to maintain commitment despite social stigma
Resource Mobilization
Core concepts: Organizational infrastructure, resource acquisition, professional vs. grassroots structures
Key findings:
Professionalized organizations excel at policy advocacy but often struggle with deep engagement
Hybrid structures combining professional leadership with grassroots participation demonstrate better long-term mobilization
Material and non-material resources both matter, but emotional resources become increasingly important for sustained involvement
Evidence strength: Moderate to strong. Comparative organizational studies show clear patterns, though causal mechanisms remain debated.
Notable research:
McCarthy and Zald’s (1977) foundational work showed how resource availability shapes movement trajectories
Staggenborg’s (1988) comparative study found professionalized organizations survived longer but mobilized fewer committed activists
Ganz’s (2000) research on the United Farm Workers demonstrated how strategic capacity depends on leadership structures and insider/outsider combinations
Framing and Messaging
Core concepts: Diagnostic, prognostic, and motivational framing; frame resonance; frame alignment
Key findings:
Single-issue framing simplifies messaging but limits identity commitment
Holistic frames connecting multiple issues create stronger commitment but reach narrower audiences
Progressive frame alignment over time builds deeper engagement than immediate ideological purity tests
Evidence strength: Moderate. Experimental and observational studies show consistent effects, though context-specific factors introduce variability.
Notable research:
Benford and Snow’s (2000) synthesis showed how framing shapes mobilization potential
Bail’s (2012) computational analysis demonstrated how emotional resonance predicts frame adoption
Jasper’s (2011) work on moral emotions highlighted how different framing strategies activate different types of commitment
Biographical Availability and Networks
Core concepts: Social ties, movement socialization, biographical constraints
Key findings:
Pre-existing network ties remain the strongest predictor of initial movement participation
Sustained engagement correlates with integration into movement-related social networks
The “biographical availability” (free time, minimal competing commitments) affects participation levels
Evidence strength: Very strong. Consistent findings across movements, methodologies, and time periods.
Notable research:
McAdam’s (1986) study of Freedom Summer showed network ties predicted high-risk activism
Passy and Giugni’s (2001) work demonstrated how networks both recruit and socialize members
Corrigall-Brown’s (2012) longitudinal research identified how life transitions affect continued participation
Emotional Dimensions
Core concepts: Moral shock, collective emotions, emotional energy, affective commitment
Key findings:
“Moral shocks” drive initial mobilization but rarely sustain long-term commitment
Positive emotions from collective action (solidarity, hope, pride) better predict sustained engagement
Groups that provide emotional rewards alongside instrumental goals show higher retention
Evidence strength: Strong and growing. Initially understudied, emotional factors now recognized as crucial through both qualitative and quantitative research.
Notable research:
Jasper’s (2018) work on “the emotions of protest” showed how different emotional processes operate at different stages
Collins’ (2001) interaction ritual theory demonstrated how emotional energy from successful collective actions fuels continued participation
Goodwin et al.’s (2009) edited volume synthesized evidence on how emotional processes function in movements
Application to Your Colleague’s Concerns
Your colleague’s observations align with several empirical findings:
On professional boundaries: The research strongly supports the importance of social bonds and informal connections. Corrigall-Brown found that when activism becomes integrated into participants’ broader social lives, persistence increases significantly. Their suggestion of physical community spaces aligns with findings from Haunss and Leach (2007) on the importance of “free spaces” for movement culture.
On single-issue communication: The framing literature confirms the trade-off they identify. Snow and Benford’s work on “frame bridging” suggests organizations might develop ways to connect animal issues to other concerns without requiring complete ideological alignment. Their idea of different “flavors” of thought leadership is supported by research on “multi-organizational fields” (Curtis and Zurcher, 1973).
Recommendations Based on Evidence
Hybrid engagement models: The strongest evidence supports creating tiered engagement opportunities with different commitment levels—from single-petition signers to core organizers—with pathways between levels.
Community-building infrastructure: Physical spaces, regular gatherings, and shared rituals consistently show high impact on commitment. Putnam’s (2000) work on social capital confirms the value of their community space idea.
Frame diversification: Research supports developing multiple frames for different audiences while maintaining coalition coherence, similar to their suggestion about diverse thought leaders.
Emotional cultivation: Strong evidence indicates that organizations should intentionally cultivate positive emotional experiences alongside instrumental campaigns.
Life-course integration: Help supporters integrate their animal advocacy with other life domains rather than treating it as a separate activity.
