self-selection bias

self-selection bias

a type of bias that can arise when study participants choose their own treatment conditions, rather than being randomly assigned. In such cases, it is impossible to state unambiguously that a study result is due to the treatment condition and not to the preexisting characteristics of those individuals who chose to be in this condition. Also called self-selection effect. See also sampling bias.
