Module: Assessing FIMI Impact

By SAUFEX Consortium 23 January 2026

Did Russian interference change the outcome of the 2016 US election? Did FIMI operations affect the Brexit vote? Do COVID-19 disinformation campaigns cost lives?

These questions matter enormously - but they’re exceptionally difficult to answer with confidence. Understanding FIMI impact requires grappling with complex methodology and acknowledging uncertainty.

Why Impact Assessment Matters

Understanding FIMI effectiveness helps:

  • Resource allocation: Investing in defenses proportional to threat
  • Policy responses: Designing appropriate countermeasures
  • Public awareness: Communicating the nature and scale of threats
  • Deterrence: Demonstrating consequences to adversaries
  • Learning: Understanding what works and what doesn’t

But impact assessment faces fundamental methodological challenges that make definitive conclusions difficult.

Levels of Impact

FIMI impact operates at multiple levels:

Reach: How many people saw the content?

Engagement: How many interacted with it?

Attention: Did it receive meaningful attention or just scroll-by?

Belief: Did people believe the claims?

Attitude change: Did it shift opinions?

Behavior: Did it affect actions (voting, vaccination, etc.)?

Outcomes: Did it change election results, policy, or events?

Each level is harder to measure than the last.

Measuring Reach and Engagement

Platform data can quantify exposure:

  • Number of accounts reached
  • Impressions and views
  • Likes, shares, comments
  • Time spent engaging

Example: Facebook reported Russian IRA content reached 126 million Americans before 2016 election. This measures exposure, not effect.

But reach alone doesn’t indicate impact - millions see content they ignore or disbelieve.

The Organic Amplification Question

FIMI operations seed content, but authentic users amplify it:

  • How much reach came from inauthentic accounts vs organic sharing?
  • At what point did content become self-sustaining?
  • Would it have spread without foreign seeding?

Distinguishing foreign manipulation from organic discourse is analytically challenging - and politically fraught.

Narrative Penetration

Assessing whether narratives entered public consciousness:

Indicators:

  • Media coverage of FIMI-seeded stories
  • Political figures repeating claims
  • Survey data showing belief in specific narratives
  • Search trends related to false claims

Narrative penetration can occur even if people don’t fully believe - false claims shape the questions being debated.

Attitude Change Measurement

Determining if FIMI operations changed opinions requires:

Surveys: Tracking belief in specific claims over time (but correlation ≠ causation)

Experimental studies: Exposing people to content and measuring effects (but artificial conditions)

Natural experiments: Comparing exposed vs unexposed populations (but confounding variables)

All methods have limitations. Isolating FIMI effects from other influences is nearly impossible in real-world settings.

The Counterfactual Problem

The hardest question: What would have happened without FIMI?

  • Would Trump have won without Russian interference?
  • Would Brexit vote have been different without foreign amplification?
  • How many people died from COVID misinformation?

We can’t rerun history without FIMI to find out. This makes definitive impact claims impossible - we can only assess likelihood and contributing factors.

Electoral Impact Debates

Assessing election influence is especially contentious:

Arguments for significant impact:

  • Close elections where small shifts matter
  • Documented reach of millions of voters
  • Narrative penetration into mainstream discourse
  • Targeting of swing voters in key states

Arguments for limited impact:

  • Most content reached people already decided
  • Exposure doesn’t equal persuasion
  • Domestic factors (candidates, campaigns, economy) likely more important
  • Polarization already existed before FIMI

Honest assessment: Contributed to information environment, but magnitude unknown.

Public Health Impact

Health misinformation has measurable consequences:

  • Vaccination rates correlated with exposure to anti-vax content
  • Adoption of ineffective or dangerous “treatments”
  • Rejection of public health measures
  • Observable health outcomes (disease spread, hospitalizations, deaths)

Still, isolating foreign manipulation from domestic misinformation is difficult. But public health effects of misinformation (regardless of origin) are documentable.

Societal Polarization

FIMI operations often aim to increase division:

Measurable indicators:

  • Polarization indexes over time
  • Trust in institutions declining
  • Political violence increases
  • Social cohesion metrics

But many factors contribute to polarization beyond FIMI. Foreign operations amplify existing tensions - they rarely create them from nothing.

Assessment: FIMI contributes to polarization, but quantifying its share is difficult.

Long-Term vs. Short-Term Effects

FIMI impact varies by timeframe:

Short-term:

  • Immediate engagement and reach
  • Trending topics and news cycles
  • Election day behavior

Long-term:

  • Cumulative erosion of trust
  • Normalization of conspiracy thinking
  • Increased polarization
  • Weakened democratic institutions

Long-term effects may be more significant but harder to measure. The goal isn’t always immediate persuasion but gradual degradation of information environment.

Methodological Challenges

Impact assessment faces fundamental obstacles:

  • Selection bias: People choose what content to consume
  • Confounding variables: Many factors influence attitudes and behavior
  • Measurement: Hard to track exposure across platforms and over time
  • Causation: Correlation doesn’t prove FIMI caused observed changes
  • Self-reporting: Survey responses may not reflect true beliefs or behavior
  • Ethical limits: Can’t experimentally expose people to harmful content to measure effects

These challenges mean conclusions require qualifications and acknowledgment of uncertainty.

Cost-Benefit from Adversary Perspective

Assessing FIMI success from actor perspective:

Low costs:

  • Information operations cheap relative to military or traditional intelligence
  • Plausible deniability reduces diplomatic costs
  • Persistence possible even after exposure

Potential benefits:

  • Influence democratic processes
  • Undermine alliances and trust
  • Justify geopolitical actions
  • Defend against criticism

Even if effects are uncertain or modest, favorable cost-benefit ratio encourages continued operations.

The Perception Impact

FIMI affects perceptions regardless of measurable outcomes:

  • Awareness of foreign manipulation increases suspicion and uncertainty
  • Opponents of election results can cite foreign interference (whether it mattered or not)
  • Undermines confidence in democratic processes
  • Creates pretext for authoritarian measures

“Nothing is true and everything is possible” - even perception of widespread manipulation serves some actors’ interests.

What We Can Say With Confidence

Despite measurement challenges, some conclusions are defensible:

  • FIMI operations reach millions of people
  • Foreign-seeded narratives enter mainstream discourse
  • Operations exploit and amplify existing divisions
  • Effects likely vary by context (close elections, crises)
  • Contributing factor among many, not sole determinant
  • Long-term cumulative effects may exceed short-term measurable impacts
  • Enough evidence of harm to justify defensive investments

Implications for Defense

Impact assessment uncertainty doesn’t mean inaction:

  • We don’t need to quantify exact impact to justify defense
  • Protecting information integrity is valuable regardless of precise effects
  • Prevention is easier than measuring after-the-fact impact
  • Building resilience addresses multiple threats simultaneously
  • Democratic values justify defending information space even without perfect impact metrics

Impact assessment informs strategy, but defense doesn’t require certainty about past effects - reasonable concern about potential harm suffices.
