Psychology's credibility crisis. Does statistic matter? [Il problema della credibilità dei risultati in psicologia: quale il contributo della statistica?]

In the last ten years psychology has been accused of non-reliable and nonreplicable results. The scientific debate had acknowledged Questionable Research Practices and non-updated knowledge of statistic techniques as the main responsible of this credibility crisis. Through a literature review and practical exemplifications, the current paper introduces the debate on psychology's credibility crisis, and discusses the contribution that reliable and updated techniques of data analysis could give in response to this credibility crisis.
