Faking Science: A True Story of Academic Fraud

A book about Academic Fraud

False-Positive Citations

We describe why we wrote “False-Positive Psychology,” analyze how it has been cited, and explain why the integrity of experimental psychology hinges on the full disclosure of methods, the sharing of materials and data, and, especially, the …

False-Positive Psychology: Undisclosed Flexibility in Data Collection and Analysis Allows Presenting Anything as Significant

In this article, we accomplish two things. First, we show that despite empirical psychologists’ nominal endorsement of a low rate of false-positive findings (≤ .05), flexibility in data collection, analysis, and reporting dramatically increases …

Falsifiability Is Not Optional

Finkel, Eastwick, and Reis (2016; FER2016) argued the post-2011 methodological reform movement has focused narrowly on replicability, neglecting other essential goals of research. We agree multiple scientific goals are essential, but argue, however, …

Fearing the future of empirical psychology: Bem’s (2011) evidence of psi as a case study in deficiencies in modal research practice.

In this methodological commentary, we use Bem’s (2011) recent article reporting experimental evidence for psi as a case study for discussing important deficiencies in modal research practice in empirical psychology. We focus on (a) overemphasis on …

Feeling the Future: Experimental Evidence for Anomalous Retroactive Influences on Cognition and Affect

The term psi denotes anomalous processes of information or energy transfer that are currently unexplained in terms of known physical or biological mechanisms. Two variants of psi are precognition (conscious cognitive awareness) and premonition …

Fishing, Commitment, and Communication: A Proposal for Comprehensive Nonbinding Research Registration

Social scientists generally enjoy substantial latitude in selecting measures and models for hypothesis testing. Coupled with publication and related biases, this latitude raises the concern that researchers may intentionally or unintentionally select …

FORRT’s Open and Reproducible Science Syllabus

To provide educators with an example of how they can draw resources from FORRT’s educational nexus to integrate open scholarship into their teaching, FORRT has developed an Open and Reproducible Science 101 syllabus.

G*Power

G*Power is a tool to compute statistical power analyses for many different t tests, F tests, χ2 tests, z tests and some exact tests. G*Power can also be used to compute effect sizes and to display graphically the results of power analyses
