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,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]
