Four findings from the research
Feeling fails to scale with numbers
Our emotional system evolved to respond to individuals, not magnitudes. As the number of victims grows, our affective response grows far more slowly — and can even flatten entirely. Fetherstonhaugh and colleagues (1997) called this “psychophysical numbing”: saving 4,500 lives felt less valuable to participants when the at-risk population was larger.

In a landmark experiment, Small, Loewenstein & Slovic (2007) gave participants $5. Those shown one identified child, “Rokia,” donated about twice as much as those shown famine statistics affecting millions. Strikingly, adding the statistics to Rokia's story reduced giving.

Västfjäll, Slovic, Mayorga & Peters (2014) found that donations and reported feelings were higher for one child in need than for two. Compassion does not wait for a million to fade — the “singularity effect” means the drop can start with the second victim.

“…a million deaths is a statistic” is commonly attributed to Stalin, though historians have never verified the attribution. Whatever its origin, researchers cite it because the data largely agree — and Slovic's work suggests it may even understate the problem, since compassion can begin fading after the very first victim.

Move the slider to change the number of people affected. The scene shows each additional person; the light each figure receives represents the average emotional attention research suggests an outside observer gives to each individual. The chart beneath compares how we should respond (each life valued equally) with the response pattern studies actually measure.
Drag to look around the scene.
About this model: the “observed” curve is an illustrative psychophysical function (concern ∝ N0.25, with a small singularity bonus at N = 1), shaped to match the qualitative findings of Slovic and colleagues: steep sensitivity to the first lives, rapid flattening, and near-indifference between large numbers. It is a teaching model, not a measurement of any real event.
Why the cameras point where they point
Psychology explains our hearts; news values explain the headlines. In 1965, Johan Galtung and Mari Holmboe Ruge identified the factors that make an event “newsworthy” to editors. Toggle the factors below to see how the same tragedy becomes more or less likely to receive sustained global coverage. This is descriptive — how coverage works — not a defense of it.
Estimated coverage likelihood: low
What helps us see clearly
Slovic's conclusion is not despair — it is that feelings alone are an unreliable moral compass at scale, so we should build habits and institutions that do not depend on them:
- Look for the one within the many. Stories of individuals are how our empathy works; use them as a doorway to the larger crisis, not a substitute for it.
- Trust arithmetic over intensity of feeling. If 100,000 people affected doesn't feel 100,000 times worse than one, that is a known bug in our perception — plan giving and attention deliberately.
- Notice the coverage filter. When a crisis seems “small” because it is far away or slow-moving, ask what the numbers say, not the airtime.
- Institutional commitments beat moment-to-moment emotion. Slovic argues laws and standing policies are needed precisely because compassion predictably fails at scale.
