1. Yamada, Y., Publish but perish regardless in Japan, Nature Human Behaviour,, 3, 1035, 2019.10, [URL], Here I contend that perfectionism, nepotism, and a lack of educational opportunities to learn many things required in employment are creating a “publish but perish” situation for current PhD students. The Matthew effect (“the rich get richer”), chaperone effect (“papers of junior researchers with established PIs tend to be published in top journals”), and predatory journals also distort the validity of publication lists. I will argue that proper researcher evaluations and recruitments are based on the diversification of positions and performance indicators..

It has become increasingly popular and been studied since 2010s, mainly in the West and Japan. Considering this, trypophobia might be a modern emotion, and hence urbanization possibly plays key roles in trypophobia. To address this issue, we compared the degree of trypophobia between urban and less urban people in China. In an experiment, we asked participants about their degree of discomfort from trypophobic images. The results showed that trypophobia occurred in both groups, although the effect size was larger in urban than less urban people. Moreover, post-experimental interviews and post-hoc analyses revealed that older people in less urban area did not experience as much trypophobia. Our findings suggest that trypophobia links to urbanization and age-related properties..

7. Ikeda, A., Xu, H., Fuji, N., Zhu, S., & Yamada, Y., Questionable research practices following pre-registration, Japanese Psychological Review, 62(3), 281-295, 2020.02, The credibility of psychological findings can be undermined by a history of questionable research practices (QRPs) by researchers. One remedy for this problem is the pre-registration of a study in which a research protocol is registered before beginning an experiment. However, the current style of pre-registration can be negatively affected by other QRPs. The purpose of this study was to demonstrate that researchers can engage in QRPs, even after a study has been preregistered. In this demonstration study, we used eight QRPs to obtain statistically meaningful results that supported an ad hoc hypothesis. Major system updates such as pre-registration, peer review, and evaluation are required to address these harmful practices. We hope that the present demonstration study provides momentum for further discussions on next-generation
research practices..
8. Yamada, Y., How to crack pre-registration: Toward transparent and open science, Frontiers in Psychology,, 9:1831, 2018.09, Pre-registration is a new research implementation and academic publishing method and has many merits. However, based on the arbitrary administration of experiments, I point out the risk that malicious researchers will use the benefits conversely for faking the validity of the research. In order to counter this, it is necessary to promote a great consciousness reform in the scientific community, to stop favoring only positive findings. Moreover, this article proposes separating theoretical and experimental parts as independent papers as one of future ways of academic publishing..
