need a response to this classmate The psychology research study looked into how hearing about the Tuskegee syphilis study made black men more skeptical of doctors and increased their risk of death. The public's knowledge of the study's unethical methods and its maltreatment of African-American men is the study's independent variable.

The use of a controlled experimental design, the random assignment of participants to groups, and the analysis of publicly available data all contribute to the study's internal validity. By eliminating potential confounding factors, such as those mentioned in the Tuskegee study's disclosure, any observed effects can be confidently assigned to the independent variable.

The collaboration with Bridge Clinical Research and the utilization of volunteers from a variety of backgrounds in Oakland, California, contribute to the study's external validity. The study also makes use of archival information, which may shed light on social ramifications beyond the sample size.

If some people are more or less inclined to volunteer for the study based on criteria like their prior healthcare experiences or level of medical skepticism, then this could be an example of selection bias. There's also the possibility of response bias, in which people give answers they think are going to be accepted by others. Furthermore, there may be inaccuracies or biases in historical data due to the techniques used to gather the data in the past.
