フリン効果（フリンこうか、英語: Flynn effect）は、流動性知能と結晶化知能の両方のテストスコアの大幅かつ長期にわたる上昇傾向のことを指す[1]。受験者のサンプルを用いて知能指数（IQ）テストを最初に標準化する際には、慣例に則り、テスト結果の平均を100に設定し、標準偏差は15または16IQポイントに設定される。IQテストを改定する際には、通常、最初のテストの被験者よりも後に生まれた集団による新しいサンプルを使用して、再び標準化する。この場合も、結果平均が100に設定されるが、新しい被験者が古いテストを受けると、ほとんどの場合平均スコアは100を大幅に上回る。

"The 'Flynn effect' is the name that has become attached to an exciting development, namely, that the twentieth century saw massive IQ gains from one generation to another. To forestall a diagnosis of megalomania, the label was coined by Herrnstein and Murray, the authors of The Bell Curve, and not by myself."

"Indeed, this effect, now called the 'Flynn effect', is well established. Nations, almost without exception, have shown gains of about 20 IQ points per generation (30 years). These gains are highest for IQ tests that are most related to reasoning and the capacity to figure out novel problems (this is often called 'fluid intelligence', see Chapter 5); and least related to knowledge, which arises from better educational opportunity, a history of persistence and good motivation for learning (this is often called 'crystallized intelligence', see Chapter 5)."
