It depends on the experiment.
In medical experiments to test the efficacy of drugs double blind tests are carried out to reduce the bias. This means the people carrying out the experiment and the people taking part have no idea who is being given the drug and who is getting the placebo.
In psychology experiments this is more difficult.

∙ 11y agoIf the scientist does a blind study, were he or she does not know which item they are testing. Personal bias will not affect the investigation. For example if the scientist has three cereals and one cereal is more expensive then the other, then maybe the scientist will pick the more expensive cereal. If he or she doesn't know which cereal is more expensive then the scientist can finish the investigation with correct information.
