The conventional alpha is .05. If a lower value, like .001, becomes the convention and nothing else changes with the research design, this will likely lead to:
A) more type 1 errors.
B) more type 2 errors.
C) more spurious publications.
D) more research published.

Lowering the alpha level decreases the likelihood of committing a type 1 error (false positive), but increases the likelihood of committing a type 2 error (false negative) as the researcher requires stronger evidence to reject the null hypothesis. This can lead to fewer significant findings and more difficulty detecting true effects, potentially leading to more type 2 errors. However, it may also increase the overall rigor of the research and reduce the likelihood of spurious publications.
