Are sample biases significantly affecting psychological experiments? 心理実験とサンプルバイアス

A large portion of disciplines, such as psychology and behavioural economics, depends on experiments utilising university/college students as subjects.  If the sample bias discussed in the article (WEIRD: Western, educated, industrialied, rich and democtatic) was significant indeed, perhaps the whole past works including e.g. those by a Nobel laureate Daniel Kahneman would need thorough review.

心理学や行動経済学等多くの学問分野は、大学生を使った実験に依存している。もし本記事が論じるようにサンプルが持つ WEIRD（西欧的、教育水準が高い、産業社会、豊か、民主的）というバイアスの影響だ重要だとしたら、ノーベル賞学者のカーネマンを始め、多くの業績を見直す必要が出てこよう。
