During these last years there has been a credibility crisis of psychology caused by events such as scientific frauds of high profile and visibility, questionable research practices, and lack of replication of some studies. After an initial part in which some of these events are described, the focus shifts on the main reasons underlying this credibility crisis. Subsequently some issues that are central to increase credibility are identified and some possible actions for each of them are examined. A series of international initiatives showing the reactivity of discipline are highlighted. The main argument of this contribution is that it is possible to increase the scientific credibility of psychology by paying close attention to several methodological aspects in daily research practices.
