What is the file drawer problem and why does it need to be addressed when conducting a meta analysis?

Abstract. The file drawer problem rests on the assumption that statistically non‐significant results are less likely to be published in primary‐level studies and less likely to be included in meta‐analytic reviews, thereby resulting in upwardly biased meta‐analytically derived effect sizes.

Publication bias is also called the file drawer problem, especially when the nature of the bias is that studies which fail to reject the null hypothesis (i.e., that do not produce a statistically significant result) are less likely to be published than those that do produce a statistically significant result.

How do you know if you’re HARKing?

HARKing occurs when researchers check their research results and then add and/or remove hypotheses from their research report on the basis of those results. This process can be disclosed or undisclosed to the readers of research reports (Hollenbeck & Wright, 2017; Schwab & Starbuck, 2017).

What is retrospective bias?

Retrospective studies are intrinsically biased by our innate human ability to discern patterns in random noise. Consider the digits of π, which are random but full of patterns. a. Starting at the 72nd digit is a sequence of 10 consecutive even numbers.

Why is HARKing a problem?

HARKing is considered to be problematic for scientific progress because it results in hypotheses that are always confirmed and never falsified by the results.

What is late Look bias?

Late Look Bias | occurs when the data is gathered or analyzed at an inappropriate time. Lead-time Bias | occurs when one test detects disease earlier so there seems to be increased survival. Publication Bias | occurs when only positive or favorable results are published.
