The Corpus of Language Discrimination in Interaction (CLDI) is an open-access, transcribed video corpus capturing real-life instances of language-based discrimination in public spaces. Compiled from citizen recordings and security footage, it …

Research funding systems fundamentally influence how science operates. This paper aims to analyze the allocation of competitive research funding from different perspectives: How reliable are decision processes for funding? What are the economic costs …

Kerr ([1998]) coined the term ‘HARKing’ to refer to the practice of ‘hypothesizing after the results are known’. This questionable research practice has received increased attention in recent years because it is thought to have contributed to low …

Notes that social psychologists' early enthusiasm has been replaced by serious doubts about the future of their field. Difficulties in conducting research, unfulfilled expectations about research payoffs, and outside pressures had all contributed to …

Evidence-based medicine is the cornerstone of clinical practice, but it is dependent on the quality of evidence upon which it is based. Unfortunately, up to half of all randomized controlled trials (RCTs) have never been published, and trials with …
