A psychologist investigates team cohesion in a corporate office by joining the department as a temporary consultant while openly disclosing their research aims to the employees.
Which of the following is true of this overt participant observation?
The researcher is highly likely to obtain natural behaviour free from social desirability bias, but must obtain retrospective consent.
The researcher's dual role can lead to a loss of objectivity, and participants may alter their behaviour due to knowing they are being studied.
This technique allows for highly standardised replication but prevents the gathering of detailed qualitative insights.
This approach completely eliminates the risk of observer bias because the researcher has direct personal experience of the environment.
