TL;DR

This study measures and predicts the speed of social mobilization through a global contest, analyzing how individual traits and network relationships affect recruitment velocity. Key findings show that direct contact from the organization, same-source type, gender homophily, younger recruiters, and younger recruits all accelerate mobilization, offering actionable insights for designing faster social campaigns.

ABSTRACT

Large-scale mobilization of individuals across social networks is becoming increasingly influential in society. However, little is known about what traits of recruiters and recruits and affect the speed at which one mobilizes the other. Here we identify and measure traits of individuals and their relationships that predict mobilization speed. We ran a global social mobilization contest and recorded personal traits of the participants and those they recruited. We identified how those traits corresponded with the speed of mobilization. Recruits mobilized faster when they first heard about the contest directly from the contest organization, and decreased in speed when hearing from less personal source types (e.g. family vs. media). Mobilization was faster when the recruiter and the recruit heard about the contest through the same source type, and slower when both individuals were in different countries. Females mobilized other females faster than males mobilized other males. Younger recruiters mobilized others faster, and older recruits mobilized slower. These findings suggest relevant factors for engineering social mobilization tasks for increased speed.

Motivation & Objective

• To identify and measure individual and relational traits that predict the speed of social mobilization.
• To understand how source types (e.g., organization, family, media) influence recruitment speed.
• To examine the role of demographic factors such as age and gender in mobilization dynamics.
• To investigate the impact of geographic distance and country differences on mobilization speed.
• To develop a predictive model for social mobilization speed based on empirical data.

Proposed method

• Conducted a global social mobilization contest to collect real-world data on recruitment chains and individual traits.
• Collected personal data including age, gender, country of origin, and source of information for recruiters and recruits.
• Tracked the time between when individuals first learned of the contest and when they recruited others.
• Used statistical modeling to analyze the relationship between individual/relational traits and mobilization speed.
• Classified source types along a personal-to-impersonal continuum (e.g., organization, family, media) to assess their impact.
• Applied regression analysis to quantify the effect of variables such as gender homophily, age, and country differences on mobilization speed.

Experimental results

Research questions

• RQ1 How does the source type through which individuals learn about a mobilization effort affect their recruitment speed?
• RQ2 To what extent does gender homophily (same-gender recruiter-recruit pairings) influence mobilization speed?
• RQ3 How do age differences between recruiters and recruits affect the speed of social mobilization?
• RQ4 Does geographic distance or country difference between recruiters and recruits slow down mobilization?
• RQ5 Can we predict mobilization speed based on individual and relational characteristics?

Key findings

• Recruits mobilized faster when they first heard about the contest directly from the organization, compared to indirect sources.
• Mobilization speed decreased significantly when the source of information shifted from personal (e.g., family) to impersonal (e.g., media).
• Recruitment was faster when both recruiter and recruit received information through the same source type, and slower when they received it through different sources.
• Mobilization was slower when the recruiter and recruit were in different countries, indicating a geographic barrier to speed.
• Females mobilized other females faster than males mobilized other males, indicating a gender homophily effect on speed.
• Younger recruiters mobilized others faster, while older recruits were mobilized more slowly, showing age-related effects on responsiveness.
