This paper is an updated English version of a report filed by a commission that the German Psychological Society (DGPs) appointed in 2022. The commission’s task was a) to identify factors in the academic system that enable and/or promote unethical behaviors, and b) to propose corrective measures. Based on expert interviews, a literature review, fee...

While many basic research fields of psychology are mostly concerned with the search for general laws, personality psychology is also—and perhaps even primarily—tasked with studying individuality. Describing, explaining, predicting, or changing the experiential-behavioral reality of the individual person requires research methodologies that support...

The interplay between persons and situations is central to psychology, and there has been a recent increase in research on psychological situation characteristics. One key issue in situation research concerns the distinction between consensual situation perceptions and subjective situation construal. We examined for the first time whether different...

Psychology is concerned with both general laws of psychological functioning and with the individual person. The debate surrounding nomothetics and idiographics has been brought up repeatedly, but it has never been completely resolved. We therefore aim to provide conceptual clarity on how the terms “idiographic” and “nomothetic” are used and how con...

Consistencies in how and what a person thinks, feels, enacts, and wants (i.e., momentary states) lie at the core of personality definitions and thus at the heart of personality psychology. Unfortunately, the systematic conceptualization and examination of state consistencies has stagnated after the person-situation debate. Moreover, past research h...

There have been tremendous advancements in technology-based assessments in new modes of data collection and the use of artificial intelligence. Traditional assessment techniques in the fields of psychology, business, education, and health need to be reconsidered. Yet, while technology is pervasive, its spread is not consistent due to national diffe...

People differ in their reaction to situations, resulting in Person × Situation interactions. These interactions have been emphasized by many theoretical accounts of personality. Nevertheless, empirical progress on Person × Situation interactions has been slow. This is in part attributable to an insufficient distinction of person and situation varia...

The use of journal impact factors and other metric indicators of research productivity, such as the h-index, has been heavily criticized for being invalid for the assessment of individual researchers and for fueling a detrimental “publish or perish” culture. Multiple initiatives call for developing alternatives to existing metrics that better refle...

The ubiquity of mobile devices allows researchers to assess people’s real-life behaviors objectively, unobtrusively, and with high temporal resolution. As a result, psychological mobile sensing research has grown rapidly. However, only very few cross-cultural mobile sensing studies have been conducted to date. In addition, existing multi-country st...

Personality Computing (PC) is a burgeoning field at the intersection of personality and computer science that seeks to extract personality-relevant information (e.g., on Big Five trait levels) from sensor-assessed information (e.g., written texts, digital footprints, smartphone usage, non-verbal behavior, speech patterns, game-play, etc.). Such sen...

During government-implemented restrictions in the wake of the COVID-19 pandemic, people’s everyday lives changed profoundly. However, there is to date little research chronicling how people perceived their changed everyday lives and which consequences this had. In a two-wave study, we examined the psychological characteristics of people’s situation...

Psychological wisdom is a growing and flourishing field of research. However, despite several promising efforts to systematically conceptualize and operationalize this construct, no consensus exists about the definition of wisdom. We argue that there is a need for integration of wisdom models to forward the field as a whole. For this purpose, we us...

Personality psychology has long focused on structural trait models, but it can also offer a rich understanding of the dynamics, processes, mechanisms, and functioning of individual differences or entire persons. The field of personality dynamics, which works towards such an understanding, has experienced a renaissance in the last two decades. This...

The COVID-19 pandemic has led to changes in people’s private and public lives that are unprecedented in modern history. However, little is known about the differential psychological consequences of restrictions that have been imposed to fight the pandemic. In a large and diverse German sample ( N = 1,320), we examined how individual differences in...

Omnibus assertions whether the Big Five (B5) or HEXACO models are “better” fall short. We argue it is more important to determine their (boundaries of) usefulness and propose a nomological network approach (NNA) to systematically compare trait structure models in a common framework. We illustrate how the NNA can be deployed to address several objec...

Objectives: Existing assessments of intellectual humility (IH)-a key component of wisdom-do not examine its manifestation in daily life while sufficiently focusing on the core idea of the construct: owning up to one's intellectual shortcomings. The present research sought to examine situational contingencies underlying daily manifestations of IH-r...
