Berkson's Paradox

Berkson's paradox, also known as Berkson's bias, collider bias, or Berkson's fallacy, refers to the situation where people's intuitive observations do not match the actual conditional probabilities and rigorous statistical results; that is, the seemingly correlated factors that people discover are actually unrelated. This occurs when biased samples are included in the study design and bias exists. The paradox was proposed by American physician and statistician Joseph Berkson in 1946.
