Abstract:  A study of the prediction of cancer and coronary heart disease on the basis of coffee consumption and personality shows that in cancer-prone probands (diagnosed on the basis of a personality inventory) coffee consumption was related to low incidence of cancer and high incidence of coronary heart disease, while diazepam showed the opposite trend. In coronary heart disease-prone probands coffee drinking was also linked with low incidence of cancer and high incidence of coronary heart disease, with diazepam again showing the opposite trend. In a personality type not prone to either disease, neither coffee consumption nor diazepam was linked with death from cancer or coronary heart disease. It is suggested that personality interacts in a predictable way with coffee and diazepam to determine in part the likelihood of death from cancer or coronary heart disease. Imipramine acts in a fashion similar to coffee, and opposite to diazepam.

 Copy pasted from https: retractionwatch.com 2019 10 07 university-finds-dozens-of-papers-by-late-and-controversial-psychologist-hans-eysenck-unsafe  The report by Kingu2019s College London into the work of Hans Eysenck and Ronald Grossarth-Maticek (....) concludes (...) We have come to the conclusion that we consider the published results of studies that included the results of the analyses of data collected as part of the intervention or observational studies to be unsafe and that the editors of the journals should be informed of our decision. We have highlighted 26 papers (Appendix 1) which were published in 11 journals which are still in existence (see list of journals and editors Appendix 2). We recommend that the Principal [of Kingu2019s College London] write to the editors of these journals to inform them that, based on our enquiry, we consider the results and conclusions of these studies are unsafe.  This article is listed as #7 in Appendix 1. ,
