Is One Study as Good as Three? College Graduates Seem to Think So, Even if They Took Statistics Classes

Abstract When people interpret the outcome of a research study, do they consider other relevant information such as prior research? In the current study, 251 college graduates read a single brief fictitious news article. The article summarized the findings of a study that found positive results for a new drug. Three versions of the article …
