Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Political scientists use short vignettes or mock news stories to embed treatments in experimental survey designs. We investigate whether the choice of medium entails a trade-off between internal and external validity. On the one hand, short vignettes may improve internal validity by isolating key variables without overloading respondents with information, thereby leading to satisficing and degrading data quality. On the other hand, mock news stories may improve external validity by approximating the circumstances under which individuals consume political information, which may enhance the credibility of the information. We find no evidence, however, that short vignettes mitigate satisficing more than mock news stories. Nor do we find that mock news stories enhance individual perceptions of the credibility of the information. Instead, we' .
