Understand the Problem
The question is asking about the implications of selection bias in natural environment studies, specifically focusing on why it is a concern. The options provided suggest different potential issues related to selection bias.
Answer
Selection bias can cause over or underestimation of effects and affect study reliability.

Answer for screen readers
Selection bias can lead to overestimation or underestimation of effects in natural environment studies, which can compromise the reproducibility and reliability of research results.
More Information
Selection bias is a significant concern in natural environment studies because it can compromise the internal and external validity of the research. It can skew the results by affecting how representative the sample is of the target population. By not accurately representing the conditions of the general environment, conclusions drawn can be misleading or incorrect.
Tips
A common mistake is assuming that selection bias does not exist in prospective cohort or longitudinal studies; however, it can still occur if the population is not representative.
