Theoretical Unification

The outline for theoretically unified psychology is offered. A new epistemological system is used to provide a unique vantage point to examine how psychological science exists in relationship to the other sciences. This new view suggests that psychology can be thought of as existing between the central insights of B. F. Skinner and Sigmund Freud. Specifically, Skinner's fundamental insight is merged with cognitive neuroscience to understand how mind emerges out of life. This conception is then joined with Freud's fundamental insight to understand the evolutionary changes in mind that gave rise to human culture. By linking life to mind from the bottom and mind to culture from the top, psychology is effectively boxed in between biology and the social sciences.

Ordinal Level

Most theories in the social sciences are verbal and provide ordinal-level predictions for data. For example, a theory might predict that performance is better in one condition than another, but not by how much. One way of gaining additional specificity is to posit many ordinal constraints that hold simultaneously. For example a theory might predict an effect in one condition, a larger effect in another, and none in a third. We show how common theoretical positions naturally lead to multiple ordinal constraints. To assess whether multiple ordinal constraints hold in data, we adopt a Bayesian model comparison approach. The result is an inferential system that is custom-tuned for the way social scientists conceptualize theory, and that is more intuitive and informative than current linear-model approaches.

The new mobilities paradigm has been influential within the social sciences for the past two decades. And yet, psychology is undoubtably slow to incorporate mobility as a key lens through which to consider its subject area. In this editorial, I will make the case that we would benefit greatly from focusing more on personal, collective and psychological mobilities and the kinds of conceptual, methodological and practical challenges they raise. To illustrate this, I briefly discuss the notions of self and identity, learning, and imagination and creativity. Final conclusions are offered regarding a late but welcomed ‘mobilities turn’ in psychological science.

We suggest that human culture exhibits key Darwinian evolutionary properties, and argue that the structure of a science of cultural evolution should share fundamental features with the structure of the science of biological evolution. This latter claim is tested by outlining the methods and approaches employed by the principal subdisciplines of evolutionary biology and assessing whether there is an existing or potential corresponding approach to the study of cultural evolution. Existing approaches within anthropology and archaeology demonstrate a good match with the macroevolutionary methods of systematics, paleobiology, and biogeography, whereas mathematical models derived from population genetics have been successfully developed to study cultural microevolution. Much potential exists for experimental simulations and field studies of cultural microevolution, where there are opportunities to borrow further methods and hypotheses from biology. Potential also exists for the cultural equivalent of molecular genetics in “social cognitive neuroscience,” although many fundamental issues have yet to be resolved. It is argued that studying culture within a unifying evolutionary framework has the potential to integrate a number of separate disciplines within the social sciences.

Theoretical Unification

Psychological science can benefit from a theoretical unification with other social sciences. Social psychology in particular has gone through cycles of repression, denying itself the opportunity to see the calculating element in human interaction. A closer alignment with theories of evolution and theories of interpersonal (and intergroup) games would bring strategic reasoning back into the focus of research.

And Behavior

The present lack of sample diversity and ecological theory in psychological science fundamentally limits generalizability and obstructs scientific progress. A focus on the role of socioecology in shaping the evolution of morphology, physiology, and behavior has not yet been widely applied toward psychology. To date, evolutionary approaches to psychology have focused more on finding universals than explaining variability. However, contrasts between small-scale, kin-based rural subsistence societies and large-scale urban, market-based populations, have not been well appreciated. Nor has the variability within high-income countries, or the socioeconomic and cultural transformations affecting even the most remote tribal populations today. Elucidating the causes and effects of such broad changes on psychology and behavior is a fundamental concern of the social sciences; expanding study participants beyond students and other convenience samples is necessary to improve understanding of flexible psychological reaction norms among and within populations. Here I highlight two examples demonstrating how socioecological variability can help explain psychological trait expression: (i) the role of environmental harshness and unpredictability on shaping time preference and related traits, such as impulsivity, vigilance, and self-efficacy; and (ii) the effects of industrialization, market integration, and niche complexity on personality structure. These cases illustrate how appropriate theory can be a powerful tool to help determine choices of diverse study populations and improve the social sciences.

SUMMARY DOCTORAL DISSERTATION: Psychology is facing a “replication crisis”. Many psychological findings could not be replicated in novel samples, which lead to the growing concern that many published findings are overly optimistic or even false. In this dissertation, we investigated potential indicators of problems in the published psychological literature. In Part I of this dissertation, we looked at inconsistencies in reported statistical results in published psychology papers. To facilitate our research, we developed the free tool statcheck; a “spellchecker” for statistics. In Part II, we investigated bias in published effect sizes. We showed that in the presence of publication bias, the overestimation of effects can become worse if you combine studies. Indeed, in meta-analyses from the social sciences we found strong evidence that published effects are overestimated. These are worrying findings, and it is important to think about concrete solutions to improve the quality of psychological research. Some of the solutions we propose are preregistration, replication, and transparency. We argue that to select the best strategies to improve psychological science, we need research on research: meta-research.

Abstract. Factorial survey experiments are increasingly used in the social sciences to investigate behavioral intentions. The measurement of self-reported behavioral intentions with factorial survey experiments frequently assumes that the determinants of intended behavior affect actual behavior in a similar way. We critically investigate this fundamental assumption using the misdirected email technique. Student participants of a survey were randomly assigned to a field experiment or a survey experiment. The email informs the recipient about the reception of a scholarship with varying stakes (full-time vs. book) and recipient’s names (German vs. Arabic). In the survey experiment, respondents saw an image of the same email. This validation design ensured a high level of correspondence between units, settings, and treatments across both studies. Results reveal that while the frequencies of self-reported intentions and actual behavior deviate, treatments show similar relative effects. Hence, although further research on this topic is needed, this study suggests that determinants of behavior might be inferred from behavioral intentions measured with survey experiments.
