e/Experimenter's bias

Information
has gloss	eng: In experimental science, experimenters bias is bias towards a result expected by the human experimenter. David Sackett , in a useful review of biases in clinical studies, states that biases can occur in any one of seven stages of research: # in reading-up on the field, # in specifying and selecting the study sample, # in executing the experimental manoeuvre (or exposure), # in measuring exposures and outcomes, # in analyzing the data, # in interpreting the analysis, and # in publishing the results. The inability of a human being to remain completely objective is the ultimate source of this bias. It occurs more often in sociological and medical sciences, for which reason double blind techniques are often employed to combat the bias. But experimenters bias can also be found in some physical sciences, where the experimenter rounds off measurements.
