Reducing Bias in Studies

Definition

Bias

Bias is a systematic error that can distort the results of a study, leading to invalid conclusions.

Note

Bias can occur at any stage of the research process, from the design of the study to the interpretation of the results.

Double-Blind Procedure

The double-blind procedure is a technique used to eliminate bias in experiments
It ensures that neither the participants nor the researchers know which group the participants are assigned to.

Example

Rosenthal and Fode (1963)

This study demonstrated the impact of experimenter bias on the behavior of participants.
Researchers trained two groups of students to handle rats, telling one group that their rats were "maze-bright" and the other that their rats were "maze-dull."
In reality, the rats were identical. The results showed that the "maze-bright" rats performed better, highlighting the influence of researcher expectations on participant behavior.
