Psychology is fragmented into the study of a myriad of constructs and measures, most of which are used very rarely. This hinders cumulative knowledge generation. We call on the field to defragment psychology and prevent further fragmentation. We provide four key recommendations to achieve this and summarize the needed actions.

Abstract Given the ubiquity of exploration in everyday life, researchers from many disciplines have developed methods to measure exploratory behaviour. There are therefore many ways to quantify and measure exploration. However, it remains unclear whether the different measures (i) have convergent validity relative to one another, (ii) capture a domain general tendency, and (iii) capture a tendency that is stable across time.

Research shows that people's self-reports may be biased by an initial elevation phenomenon in which ratings are higher the first time that people take a survey as compared to the second and subsequent times. Apart from the fact that this phenomenon exists, and that it might bias ratings for negative subjective experiences more strongly than positive ones, little else is known.
