counterfactualsとは 意味・読み方・使い方

Mainstreaming of disaster prevention in development agenda may be difficult because the results of disaster prevention efforts could be observed only when a disaster actually occurred, and also because it would be extremely difficult to measure how much prevention efforts would have mitigated the damage against the counterfactuals.発音を聞く 例文帳に追加

開発における「防災の主流化（mainstreaming）」が困難な理由は、実際に災害が発生しなければ防災の効果が見えないこと、また、防災の取組によってどの程度被害が軽減されたかを知ることが極めて困難であるためです。 - 財務省
