The scientific quality of social and personality psychology has been debated at great length in recent years. Despite research on the prevalence of Questionable Research Practices (QRPs) and the replicability of particular findings, the impact of the …

Theories in "soft" areas of psychology (e.g., clinical, counseling, social, personality, school, and community) lack the cumulative character of scientific knowledge because they tend neither to be refuted nor corroborated, but instead merely fade …
Because physical theories typically predict numerical values, an improvement in experimental precision reduces the tolerance range and hence increases corroborability. In most psychological research, improved power of a statistical design leads to a …
A crise de confiança na ciência. Práticas e condutas questionáveis na pesquisa. Delineamento experimental adequado. Definição de variáveis. Armadilhas à validade. Cálculo amostral. Transparência na pesquisa. Pré-registro. Dados e código aberto.
