Preferential Attachment with Local Flexibility
Physical Review Letters · Tingyu Zhao, Balázs Maga, Pierfrancesco Dionigi et al. (incl. István A. Kovács)
What it shows
The researchers modify preferential attachment so that a new node's intended link can instead form with another node in the target's local neighbourhood. This small change, motivated by quantum networks, produced substantially different structures, with different forms of hierarchy and degree distribution depending on attachment strength; the resulting networks are small-world rather than scale-free.
Why it matters for Fame Engineering
Local flexibility changes global structure. Connecting with a powerful node may open routes into its neighbourhood, so second-order opportunities matter, and not every information environment follows the same winner-takes-most rule.
Growth rules shape the network; not every system is winner-takes-most.

Automated Influence: How Social Bots Reshape Discursive Opportunities in Online Activism
Social Media + Society · Linda Li, Helen Margetts
What it shows
Linda Li and Helen Margetts examined automated social-media activity around Black Lives Matter and Extinction Rebellion and organised influence into visibility (being encountered), resonance (connecting emotionally or culturally) and legitimacy (being seen as credible). In the BLM sample, pro-movement bots concentrated on resonance while opposing ones attacked legitimacy; in the XR sample, supportive bots focused on legitimacy and participation while opposing activity downplayed the movement's importance.
Why it matters for Fame Engineering
Visibility, resonance and legitimacy are three separate achievements. A campaign can dominate attention without changing what people value or establishing credibility; the challenge is combining all three.
A brand can dominate a conversation without dominating its meaning.

Rewiring the Majority: Structural Median Opinion Control in the Friedkin-Johnsen Model
arXiv · Elisabetta Biondi, Chiara Boldrini, Andrea Passarella, Marco Conti (IIT-CNR)
What it shows
Using the Friedkin-Johnsen opinion model, the researchers developed methods to identify new connections that would shift the eventual median opinion of a network, tested on synthetic and real network structures. Adding well-chosen edges was often more cost-effective than directly targeting highly influential individuals once the cost of reaching them was considered.
Why it matters for Fame Engineering
Value can come from creating connections between communities that rarely exchange information, not only from winning attention from existing hubs.
Sometimes the best intervention is a new connection, not a bigger megaphone.

Popularity-driven interactions in multilayer bounded-confidence opinion dynamics
arXiv · Senne De Bruyn, Luis Enrique Correa Rocha (Ghent University)
What it shows
The model has two overlapping layers: people's existing social ties and a broader 'explore' layer through which they meet unfamiliar accounts. Without popularity bias, wider exposure mixed separate groups and reduced opinion diversity; when discovery favoured already-popular accounts, a few highly visible users became opinion attractors that could preserve distinct clusters and sustain polarisation.
Why it matters for Fame Engineering
More visibility does not automatically mean broader acceptance. Depth (how strongly a community holds an association) and breadth (how many distinct communities hold it) are different, and repeatedly targeting the same popular accounts can entrench concentration.
Popularity bias can deepen clusters instead of bridging them.

Educational intervention can rewire village social networks
Nature · Marios Papamichalis, Laura Forastiere, Edoardo M. Airoldi, Nicholas A. Christakis
What it shows
In a randomised trial with 8,331 people across 110 Honduran villages, a 22-month health-education intervention changed existing social relationships. Where coverage was low (5% to 30% of households), participants tended to drop health-advice ties to untreated people; where it was high (50% to 100%), treated people became more connected to each other, and changes extended to friendships and financial ties. Networks re-mapped three to four years after the intervention ended (in 56 villages) showed lasting change mainly in the low-coverage villages, while overall degree distributions stayed fairly stable.
Why it matters for Fame Engineering
Information interventions can reorganise who people regard as credible or worth consulting, not just flow through existing networks. Successful education around an attribute could build new relationships around that attribute. This is an extrapolation from a health setting.
Information does not just spread through networks; it can rewire them.

Contagion-preserving compression for multiscale epidemic modeling
Science Advances · Leyang Xue, Zengru Di, An Zeng
What it shows
The paper introduces Iterative Structural Coarse-Graining, a way to simplify large networks while preserving contagion behaviour. Dense local structures can act like larger collective spreading units once transmission inside them saturates, and the multiscale representations supported influence-maximisation, immunisation and surveillance strategies that beat the centrality-based comparisons tested.
Why it matters for Fame Engineering
Large network maps can be simplified by treating tightly knit communities as single spreading units, then studying the links between them, without losing the dynamics that matter.
Map communities as spreading units, then study the bridges between them.

Mesoscale structures in signed networks
Science Advances · Wei Zhang, Olga Boichak, Tristram J. Alexander, et al. (incl. Tiago P. Peixoto, Eduardo G. Altmann)
What it shows
The researchers examined 24 empirical signed networks (positive and negative ties) across social, political, financial and biological settings, using a method that does not assume social-balance patterns in advance. Real networks often had more complex structures than balance theory predicts; core-periphery structures were common in online social networks, and small-group patterns did not necessarily describe the wider network.
Why it matters for Fame Engineering
Not all mentions are equivalent relationships. Criticism inside a highly connected core means something different from criticism on the periphery, and positive sentiment in one cluster does not prove reputation elsewhere.
Where a negative tie sits matters as much as that it exists.

Community-centric modeling of citation dynamics explains collective citation patterns across different knowledge systems
Nature Communications · Sadamori Kojaku, Robert Mahari, Sandro Claudio Lera, et al. (incl. Esteban Moro, Alex Pentland, Yong-Yeol Ahn)
What it shows
Studying citation networks in science, patents and US legal decisions, the authors find similar collective patterns across all three, including delayed recognition. Their Community Citation Model explains citations by how the whole knowledge community moves through a conceptual space, rather than only by a publication's fitness, popularity and age. Work can sit largely undiscovered for years and then become influential once the community starts exploring its subject, and the model improved predictions of future citations.
Why it matters for Fame Engineering
The success of an information asset depends partly on where the surrounding conversation is heading. Raising the importance of an attribute across a category can make an existing strong association with it far more valuable.
Ideas win when the community moves towards them.

Emergence of polarization in networks of large language model agents
Nature Communications · Jinghua Piao, Zhihong Lu, Chen Gao et al. (incl. Fernando P. Santos, Yong Li, James Evans)
What it shows
Researchers simulated thousands of interacting LLM agents built on five models, including GPT-3.5, GPT-4o, ChatGLM, Llama-3 and DeepSeek-V3. Without opinion-dynamics rules being programmed in, the agents formed homophilic clusters and polarisation patterns resembling human social networks. The authors then tested interventions such as encouraging more diverse interaction and reducing confirmation bias.
Why it matters for Fame Engineering
AI-mediated environments can develop their own reinforcing communities. Association strength inside one community and penetration across communities need to be measured separately.
An association can be strong inside a cluster and invisible outside it.

A study of the "Breakthrough of Localized Influence" in regional sports events: agenda, emotion, and cultural identity
Humanities and Social Sciences Communications · Hanxiao Shi, Qiuling Cheng, Jiali Gao, Huilan Jin
What it shows
Researchers studied how China's Jiangsu City Football League became a national cultural phenomenon, using 222,027 Weibo posts and comments and 743,794 TikTok video titles and comments, combining social network analysis, topic modelling and sentiment analysis. Weibo communication tended to follow a hierarchy from official media through opinion leaders to the public, while on TikTok audiences played a more active role in reconstructing the narrative. Agenda formation, emotional resonance and cultural identity were linked elements.
Why it matters for Fame Engineering
Distributing a message is different from having it socially adopted. An association becomes more consequential when independent communities start expressing and reinforcing it themselves, and different platforms create different paths to fame.
Fame takes hold when audiences start retelling the story themselves.

Green knowledge transaction networks, knowledge absorptive capacity and breakthrough green innovation
Journal of Knowledge Management (Emerald) · Hao Li, Yi Yu, Shoujian Jiang, Yiming Cao
What it shows
Using structural-hole theory, the authors examine whether advantageous positions in green knowledge transaction networks relate to breakthrough innovation. Structural-hole advantage was positively associated with highly cited green innovation; knowledge retrieval and integration capabilities helped convert position into outcomes, absorptive capacity strengthened the effect, and the advantage persisted over time but weakened.
Why it matters for Fame Engineering
Sitting between communities is not enough; value depends on converting what flows through that position into something useful. A bridging node that can accurately carry and translate a specific meaning may be worth more than a more central one that cannot.
Brokerage only pays when the broker can carry the meaning.

Attentional DoS: Repeat Reposting, Collective Attention, and Information Diffusion on X
arXiv · Genta Toya, Bruno T. Sugano, Kei Ichikawa, et al.
What it shows
The researchers analysed large X cascades with at least 1,000 reactions and accounts that repeatedly undo and redo reposts, putting the same item back into followers' timelines. The raw number of repetitions was not the strongest predictor of later audience growth; the reach of the accounts doing the repeating mattered more. Several habitual amplifiers sometimes converged on one post, giving it repeated temporal coverage.
Why it matters for Fame Engineering
Temporal coverage matters alongside spatial reach: an association that re-enters attention repeatedly through credible, high-reach nodes may have more cumulative impact than one large moment. Who repeats matters more than how often.
Who repeats an idea matters more than how many times it is repeated.

Group dynamics of engagement with AI topics on Bluesky
arXiv · Bradley Huynh, Moyi Tian, Nancy Rodríguez
What it shows
Using the release of DeepSeek R1 as a case study, the researchers modelled engagement across Bluesky communities with a spreading model that separates endogenous propagation through the network from exogenous response to the event itself. Communities with a strong initial reaction did not necessarily show strong later network-driven propagation.
Why it matters for Fame Engineering
A launch spike does not show that an idea has entered the network. Campaign response and network propagation are different, and the second is closer to what lasting fame means.
A big launch spike is not the same as an idea spreading.

RecToolBench: Benchmarking Recommendation-Specific Tool Orchestration under Fuzzy User Intent
arXiv · Xiao Chen, Yicheng Zhao, Yingying Wu, et al.
What it shows
RecToolBench contains 1,288 recommendation tasks across Amazon Electronics, Yelp and Foursquare, using 13 MCP servers and 32 tools, and deliberately phrases requests as fuzzy human intent. Models often made technically valid tool calls but still recommended poorly, because they failed to translate vague language into the right parameters, chose the wrong evidence source, lost dependencies between steps or failed to integrate retrieved evidence.
Why it matters for Fame Engineering
Real buyers state vague needs, and the system has to infer the hidden decision criteria and then find evidence for them. 'Attribute retrievability', how easily an AI can infer, locate and substantiate why a brand should win, becomes central.
AI has to infer the reason to choose before it can find the brand that owns it.

Popping misinformation bubbles: persona-informed style-based messaging in Facebook ad experiments
Journal of Computational Social Science (Springer) · JooYoung Lee, Emily Booth, Hany Farid, Marian-Andrei Rizoiu
What it shows
After months studying fringe Facebook communities, researchers identified characteristic personas and communication styles, then ran A/B ad tests comparing consensus information written in a neutral government style with the same information written in each community's style. The community-styled versions drew higher click-through in 11 of 12 paired comparisons. The study measured clicks, not belief change.
Why it matters for Fame Engineering
Semantic consistency does not require message uniformity. The same core association can travel further when each community expresses it in its own register.
Keep the meaning constant; let each community choose the words.
Source checked 19 Oct 2026. Corrected: styled versions won 11 of 12 comparisons (not every one); a significance claim could not be verified and was removed.
Optimal and heuristic strategies for evaluating the influence of coordinated behavior in information cascades and retweet networks
arXiv · Niccolò Di Marco, Matteo Cinelli, Shinichi Nakano, et al.
What it shows
Once coordinated accounts have been identified, how much influence did their position in the diffusion structure give them? Analysing the 2019 UK General Election and several verified state-backed information operations, the authors found coordinated accounts had fairly limited influence in the UK election cascades, but across other campaigns results varied widely, with several operations matching or exceeding structurally central seed sets.
Why it matters for Fame Engineering
Activity volume is not influence, and centrality alone is not a universal measure. Placement along actual propagation paths matters, so one well-placed mention can outweigh many poorly placed ones.
Position on the propagation path beats volume of activity.

When Social Media Influencers Work: A Meta-Analysis of Brand Engagement, Behavioral Intention, and Boundary Conditions
Journal of Consumer Behaviour (Wiley) · Tareq Rasul, Fernando de Oliveira Santini, Weng Marc Lim et al.
What it shows
The meta-analysis combines 97 studies and 40,330 participants. Influencer attractiveness had a significant direct link with brand engagement, while expertise had the strongest direct link with behavioural intention, with trustworthiness and attractiveness also contributing. The authors describe this as a division of persuasive labour.
Why it matters for Fame Engineering
Influence is not a single score. Different nodes perform different functions: some generate attention, some establish expertise, some cross into new communities, some trigger action.
Attention and trust are different jobs, often done by different people.

Spectral Dynamics of DeepWalk Embeddings for Dynamic Network Change-Point Detection
arXiv · Houlin Zhou, Yejin Wang, Xufei Tang, et al.
What it shows
The researchers embed successive snapshots of a changing network with DeepWalk and use the spectral behaviour of those embeddings to detect when structure shifts enough to count as a genuine transition rather than noise. The framework detected structural change in simulations and in an international trade network.
Why it matters for Fame Engineering
A network map should not be a static picture. Detecting structural change, such as a new publisher becoming central or an association moving between communities, can reveal inflection points as they happen.
The useful signal is when the network changes, not just how it looks today.

Edge-centric functional network organization reveals seizure pathways in human epilepsy
Communications Physics · Aditi Bose, Timo Bröhl, Klaus Lehnertz, Chittaranjan Hens
What it shows
Instead of focusing on which brain regions were the most important nodes, the researchers tracked the most important connections between regions over time in human epilepsy recordings. This edge-centric view revealed seizure propagation pathways, transitions and bottlenecks.
Why it matters for Fame Engineering
Influence may live in the edges as much as the nodes. A connection between a source, a brand and an attribute has its own properties (strength, recency, direction, meaning, bridging role) that node-level scores miss. The marketing application is an extrapolation.
Fame may live in the connections, not just the nodes.

Speaking of Opinions: Comparing Approaches to Modelling Opinion Manipulation
La Matematica (Springer) · Luisa Estrada, Sasha Glendinning, Andrew Nugent
What it shows
A readable review of the mathematics of opinion formation and influence, covering bounded-confidence models, leaders and followers, stubborn agents, targeted influence, influence maximisation and network inference. One strand models a small set of leaders shaping a much larger follower population; another asks which nodes to influence so a belief dominates at minimum cost; a third infers hidden network structure from how a network responds to interventions.
Why it matters for Fame Engineering
It separates making information available from changing the distribution of belief in a network. Influencing the clusters whose adoption shifts what neighbouring communities value may matter more than broadcasting evenly.
Changing what a network believes is not the same as reaching it.

Copying explains the collective behavior of AI agents in the wild
arXiv · Giordano De Marzo, Nicola Alboré, David Garcia
What it shows
The authors analysed a real incident in which thousands of short-lived AI agents independently found a public wiki and began leaving information for later agents. Across three decisions (where to write, what to call themselves and how to phrase messages) agents chose an option with a probability close to that option's share of what was currently visible to them. Simple copying models reproduced the heavy-tailed concentration and local conventions seen in the real population.
Why it matters for Fame Engineering
Visibility can become self-reinforcing because being encountered raises the chance of being copied, which raises future visibility. The driver was what was visible at the time, not intrinsic quality or established authority, which suggests early availability in the information flow can matter as much as authority.
Visible, copied, more visible, copied again.

Fame Engineering ideas
These are working models drawn from the research above. They organise thinking and measurement; none is a validated equation or a proven law.
Fame durability (working model)
A conceptual model, not a validated equation. A citation, mention or link is an event; fame is what remains after the events pass.
Fame strength (measurement model)
A way of organising measurement, not a literal formula. The question it asks: how consistently, how independently, across how many relevant communities and for how long is a brand associated with the reason it should win?
The five conditions of fame
- Attribute salience
- Does the market consider the advantage important?
- Association strength
- Does the market connect that advantage with the brand?
- Legitimacy
- Is there credible, independent evidence supporting the association?
- Network distribution
- Does the association exist across the relevant information communities?
- Persistence
- Does the association survive after the original activity stops?
Proposed strategic dimensions, not scientifically validated measurements of fame.
Visibility, resonance, legitimacy
Three separate achievements (after Li and Margetts): being encountered, being felt to matter, and being believed. A campaign can win one without the others.
Depth versus breadth
Depth is how strongly one community holds an association; breadth is how many distinct communities hold it. Popularity-biased exposure can deepen a cluster without spreading the association.
Attribute retrievability
How easily an AI system can infer the decision criterion behind a vague request, locate evidence for it and substantiate why a brand wins on it.
Exposure-conditioned copying
Visible → copied → more visible → copied again. Accumulated fame may begin with availability at the right point in the information flow, not only with authority.
Four network roles
- Authorities
- Create trusted information: original data, definitive explanations, strong evidence.
- Hubs
- Select and distribute authorities: journalists, review and comparison sites, curated newsletters, AI recommendation systems.
- Bridges
- Move information between otherwise separate communities.
- Echo nodes
- Create repetition within a community.
Builds on Kleinberg's hubs-and-authorities (HITS) idea: authority is contextual to a topic, not universal.
An honest open question
Preferential attachment in AI citation remains plausible but unproven. Studies show inherited popularity, stable cores and feedback loops in simulated or single-platform settings, but none yet shows that receiving one AI citation causally increases the chance of the next. Persistent page-query relationships may come from stable hidden rankings rather than citation feedback.
