Researchers often use computers in their experiments to keep from influencing the participants and to keep themselves <u>blind</u> regarding the conditions to which the participants have been assigned.
<h3><u>Why is research blinding crucial?</u></h3>
Blinding is crucial to prevent bias (such as observer bias and demand characteristics) and guarantee the internal validity of a study.
Participants may alter their behavior in ways that affect the outcome that researchers are aiming to measure if they are aware of whether they are in a control or treatment group. If those providing the treatment are aware of the participants' assigned groups, they may treat them differently, which could either directly or indirectly affect the outcome.
