盲實驗

盲實驗（英文：blind experiment）係指做實驗嗰陣特登隱瞞某啲可能會對實驗結果產生影響嘅資訊。

雙盲實驗

雙盲實驗（英文：double-blind experiment）係醫學同社會科學成日用嘅一種實驗技巧，指做實驗嘅人同受試者喺實驗結束之前都唔知每位受試者屬邊組。

想像家陣有位醫學研究者想做臨床試驗試隻新藥，但佢實驗未做完就話嗮俾班實驗組嘅受試者知，佢哋食嘅係新藥唔係安慰劑，班受試者信隻藥有效而最後因為噉而感覺舒服咗；事實上，「諗住自己食咗隻特效藥（但隻藥實際上係冇用嘅安慰劑）會令病人主觀感覺舒服咗」－即係所謂嘅安慰劑效應－呢種現象喺廿世紀嘅醫學上經已廣受人討論^[1]。

為咗防止安慰劑效應噉嘅現象，廿一世紀初嘅人類實驗實會用雙盲法－唔俾受試者知邊個入咗實驗組邊個入咗對照組，而且啲研究員喺實驗結束之前亦都唔會知呢樣資訊，費事研究員唔小心或者無意識噉泄露資訊（兩邊都睇唔到樣資訊，所以叫雙盲）^[2]。
