- 1雙盲（醫學／實驗用語）
In a fair test of a medicine or an idea, you do not want hope or fear to change the result. In a double-blind study, two groups are compared, and neither the people in the study nor the scientists running it know who is in which group. One group may get the real treatment; the other may get a pill with no medicine in it, or a different treatment. That information is locked away until the end. “Blind” here does not mean unable to see with your eyes; it means “not told which group is which”. There is also single-blind, where only the people being studied are kept in the dark, and the researchers know. Double-blind is the stricter kind, and people trust it more, especially for new medicines. You will hear it in science news and hospital research. It is a specialist word, but newspapers often use it without stopping to explain.
在公平的醫藥或實驗測試裡，我們不希望期待或害怕影響結果。雙盲研究會比較兩組，參與的人和主持研究的科學家都不知道誰在哪一組。其中一組拿到真正的治療，另一組可能拿到沒有藥效的藥丸，或是另一種治療，這些資訊要到最後才揭曉。這裡的 blind 不是看不見，而是不知道哪一組是哪一組。
單盲則是只有受試者不知道，研究人員仍然知道。雙盲比較嚴格，大家也比較信任，特別是新藥。這是專業用語，常出現在科學新聞和醫院研究裡，常見的說法是「a double-blind ＿＿」，例如「a double-blind study」。報紙也常直接用，不另外解釋。
組成double (both sides kept in the dark) + blind (not told which group is which)

- The Clever Hans effect, however, can be eliminated by means of double-blind procedures, where the person administering or scoring a test given to an animal does not know the “correct” answer.
