Resentful demoralization

This may lead to significant systematic differences in the outcome of the control group, obscuring the results of the study and threatening their validity.

Resentful demoralization can also make participants less likely to join future studies.

If people feel treated unfairly or get upset with their treatment, they might not want to be part of research again.

This can lead to fewer participants and affect the quality of future studies.

So, it's important to address these feelings to keep participants engaged and ensure good research outcomes.
