Ego-Dissolution and Psychedelics: Validation of the Ego-Dissolution Inventory (EDI)
The experience of a compromised sense of \"self\", termed ego-dissolution, is a key feature of the psychedelic experience. This study aimed to validate the Ego-Dissolution Inventory (EDI), a new 8-item self-report scale designed to measure ego-dissolution. Additionally, we aimed to investigate the specificity of the relationship between psychedelics and ego-dissolution.
Sixteen items relating to altered ego-consciousness were included in an internet questionnaire; eight relating to the experience of ego-dissolution (comprising the EDI), and eight relating to the antithetical experience of increased self-assuredness, termed ego-inflation. Items were rated using a visual analog scale. Participants answered the questionnaire for experiences with classical psychedelic drugs, cocaine and/or alcohol. They also answered the seven questions from the Mystical Experiences Questionnaire (MEQ) relating to the experience of unity with one's surroundings.
Six hundred and ninety-one participants completed the questionnaire, providing data for 1828 drug experiences (1043 psychedelics, 377 cocaine, 408 alcohol). Exploratory factor analysis demonstrated that the eight EDI items loaded exclusively onto a single common factor, which was orthogonal to a second factor comprised of the items relating to ego-inflation (rho = -0.110), demonstrating discriminant validity. The EDI correlated strongly with the MEQ-derived measure of unitive experience (rho = 0.735), demonstrating convergent validity. EDI internal consistency was excellent (Cronbach's alpha 0.93). Three analyses confirmed the specificity of ego-dissolution for experiences occasioned by psychedelic drugs. Firstly, EDI score correlated with drug-dose for psychedelic drugs (rho = 0.371), but not for cocaine (rho = 0.115) or alcohol (rho = -0.055). Secondly, the linear regression line relating the subjective intensity of the experience to ego-dissolution was significantly steeper for psychedelics (unstandardized regression coefficient = 0.701) compared with cocaine (0.135) or alcohol (0.144). Ego-inflation, by contrast, was specifically associated with cocaine experiences. Finally, a binary Support Vector Machine classifier identified experiences occasioned by psychedelic drugs vs. cocaine or alcohol with over 85% accuracy using ratings of ego-dissolution and ego-inflation alone.
Our results demonstrate the psychometric structure, internal consistency and construct validity of the EDI. Moreover, we demonstrate the close relationship between ego-dissolution and the psychedelic experience. The EDI will facilitate the study of the neuronal correlates of ego-dissolution, which is relevant for psychedelic-assisted psychotherapy and our understanding of psychosis.

Not Learning From Failure—the Greatest Failure of All
Our society celebrates failure as a teachable moment. Yet in five studies (total N = 1,674), failure did the opposite: It undermined learning. Across studies, participants answered binary-choice questions, following which they were told they answered correctly (success feedback) or incorrectly (failure feedback). Both types of feedback conveyed the correct answer, because there were only two answer choices. However, on a follow-up test, participants learned less from failure feedback than from success feedback. This effect was replicated across professional, linguistic, and social domains—even when learning from failure was less cognitively taxing than learning from success and even when learning was incentivized. Participants who received failure feedback also remembered fewer of their answer choices. Why does failure undermine learning? Failure is ego threatening, which causes people to tune out. Participants learned less from personal failure than from personal success, yet they learned just as much from other people’s failure as from others’ success. Thus, when ego concerns are muted, people tune in and learn from failure.

Ego–network stability or ego–network expansion? The effects of ego–network dynamics on recombinant innovation under heterogeneous knowledge base
PurposeThis paper aims to investigate the antecedents of recombinant innovation from the perspective of ego–network dynamics, and further disentangle whether ego–network stability or ego–network expansion is more conducive to recombinant innovation under heterogeneous knowledge base.Design/methodology/approachThis paper uses 1,801 patent data in China’s biotechnology field as a sample and adopts fixed effects regression model to examine the effects of ego–network dynamics on recombinant innovation and further uses the Wald tests to discern which ego–network dynamic is more conducive to recombinant innovation under heterogeneous knowledge base.FindingsThe empirical results indicate that ego–network dynamics have a positive impact on recombinant innovation. Specifically, for firms with high knowledge breadth and high knowledge depth as well as high knowledge breadth and low knowledge depth, ego–network stability is more conducive to recombinant innovation. By contrast, for firms with low knowledge breadth and high knowledge depth, recombinant innovation benefits more from ego–network expansion. As for firms with low knowledge breadth and low knowledge depth, both ego–network stability and ego–network expansion can promote recombinant innovation, while the effects are not significant.Practical implicationsThis research may enlighten managers to choose suitable ego–network dynamics strategies for recombinant innovation based on their knowledge base.Originality/valueThis research not only contributes to the literature on recombinant innovation by revealing the impact of different ego–network dynamics on recombinant innovation but also contributes to network dynamics theory by exploring whether ego–network stability or ego–network expansion is more conducive to recombinant innovation under a heterogeneous knowledge base.

Why and how targets’ negative workplace gossip exhort knowledge hiding? Shedding light on organizational justice
Purpose
Extant scholars identified negative workplace gossip as a social stressor that negatively influences employees’ behavior and attitude. Despite the burgeoning interest in workplace stressors, limited studies have explored how the detrimental consequences of targets’ perceived negative workplace gossip spur their emotions and behaviors. Grounding on conservation of resources and ego depletion theories, this study aims to investigate why and how targets’ negative workplace gossip may contribute to trigger knowledge hiding. Specifically, the authors explore the underlying mechanism of personal ego depletion and boundary conditions of organizational justice to shed new light on the above process.
Design/methodology/approach
Using two time-wave survey, the authors collected 340 sample data from employees working in high-tech companies of China. Hierarchical regression analysis was used to examine hypothesized relationships of moderated mediation model.
Findings
The empirical results revealed that negative workplace gossip exacerbates knowledge hiding by increasing personal ego depletion. Furthermore, through testing moderated mediation model, the results showed that organizational justice (i.e. distributive and procedural justice) with the low presence moderates the stronger strength of the linkage between negative workplace gossip and personal ego depletion, and likewise, it also moderates the stronger effect of negative workplace gossip on knowledge hiding via personal ego depletion.
Practical implications
This study recommends several guidelines for managers and practitioners to mitigate negative gossip by strengthening organizational justice.
Originality/value
This study first enriches novel understanding in the literature between negative workplace gossip and knowledge hiding by using a new emotional mechanism (i.e. personal ego depletion). This research also contributes new insights by incorporating contextual boundary conditions (i.e. organizational justice) that have not been yet researched on negative gossip and knowledge hiding linkage.

The Strength Model of Self-Control
Self-control is a central function of the self and an important key to success in life. The exertion of self-control appears to depend on a limited resource. Just as a muscle gets tired from exertion, acts of self-control cause short-term impairments (ego depletion) in subsequent self-control, even on unrelated tasks. Research has supported the strength model in the domains of eating, drinking, spending, sexuality, intelligent thought, making choices, and interpersonal behavior. Motivational or framing factors can temporarily block the deleterious effects of being in a state of ego depletion. Blood glucose is an important component of the energy.
