It is the proper role of a psychological research scientist to:

question data.
make safe predictions.
keep research methods accessible only to those involved in the research.
avoid making predictions.

I vote for the first answer.

If you don't know the right answer, try eliminating those you know are wrong. I wasn't sure about the first choice, but I know the others are wrong.

The proper role of a psychological research scientist is to question data, as it is an essential part of the scientific process. By questioning data, scientists thoroughly scrutinize the results to ensure accuracy and validity. This involves critically examining the methods used, analyzing the statistical significance of the findings, and considering any potential biases or limitations in the study design.

To determine the correct answer among the options provided, we can evaluate each statement against the role of a psychological research scientist:

1. Question data: This aligns with the role of a scientist, as explained above.

2. Make safe predictions: While predictions can be a part of psychological research, the term "safe" may imply a more conservative or risk-averse approach. In research, scientists strive for accurate predictions based on the evidence at hand, rather than "playing it safe." Therefore, this statement does not accurately describe the role of a psychological research scientist.

3. Keep research methods accessible only to those involved in the research: Transparency and the sharing of research methods are fundamental principles of scientific research. Communication and collaboration with other scientists and the wider scientific community allows for critical evaluation and verification of research findings. Consequently, scientists do not typically restrict access to research methods. Therefore, this statement is not consistent with the role of a psychological research scientist.

4. Avoid making predictions: Making predictions is a significant component of psychological research. Scientists often hypothesize and test specific predictions to advance our understanding of human behavior and mental processes. Therefore, this statement does not accurately represent the role of a psychological research scientist.

Based on this analysis, the statement "question data" is the most appropriate description of the proper role of a psychological research scientist.
