The same chart, three ways

The chart from r/dataisbeautiful looks damning: the US paying nearly 100% of NATO, Trump’s talking point rendered as a bar the length of the page ▸ 40:44. Then the maker does the honest thing and re-plots the same data. Because it’s total spending, and the US economy is roughly all of Europe plus half of Russia in size ▸ 41:08, the absolute number tells you about the denominator, not the burden. Per capita, the US sits at the average, below Norway ▸ 40:54. As a share of GDP, it’s 3.2%, “como quitarle un pelito” ▸ 41:48, less than Poland or Latvia.

The teaching is stated plainly and it’s the entry’s whole point: “siempre hay que tomar la información completa y verla desde diferentes ángulos” ▸ 42:42. A single chart is a single choice of denominator, and the choice is the argument.

una sola gráfica es una sola elección de denominador; el denominador es el argumento →

The counter-example he offers makes it bipartisan and concrete: Petro trying to read a crime map and drawing perverse conclusions from it ▸ 42:57, “todos los asesinatos están en la cordillera oriental,” when the map simply shows more murders in big cities ▸ 43:37, Bogotá, Medellín, Cali, because big cities have millions of people. Plot it per capita and the alarm mostly evaporates ▸ 44:02. Both the NATO defender and the crime-map politician commit the identical error, mistaking a raw count for a rate, which is why the entry’s real subject isn’t NATO or crime but the reflex the diary keeps sharpening: the number that confirms your point is exactly the one to re-normalize before you trust it…
