After I found out about the panel discussion on Good Scientific Practice at the University of Cologne via Twitter, I joined yesterday to watch the discussion as it was closely related to my thesis’ topic.
The panel was filled with five professors and one junior professors from different faculties, whose positions were related to “good vs bad science” in some way.

The German Society of Psychology (DGPs) today announced that the court of honor has put an end to its investigation on Jens Förster after they mutually agreed to the retraction of two papers in the Journal of Experimental Psychology: General:
By this [agreement] the proceedings against Prof. Dr. Jens Förster at the court of honor at the German Society of Psychology will be concluded. Prof. Förster is obliged to act upon the publishers of the Journal of Experimental Psychology to pursue a retraction of the following to publications:
Förster, J. (2009). Relations between perceptual and conceptual scope: How global versus local processing fits a focus on similarity versus dissimilarity. Journal of Experimental Psychology: General, 138(1), 88-111. http://dx.doi.org/10.1037/a0014484
Förster, J. (2011). Local and global cross-modal influences between vision and hearing, tasting, smelling, or touching. Journal of Experimental Psychology: General, 140(3), 364-389. dx.doi.org/10.1037/a0023175
This settlement is neither a confession of guilt by Prof. Förster nor an imputation of blame by the court of honor.
Past analyses and reports have hinted at a possible scientific misconduct, but he always denied those claims. However, this settlement is rather strange to me: either there is sufficient evidence of fake data or very questionable practices or there is none. In the first case, an investigation should formally be started to identify any publication that might be based on those data. And in the latter case a retraction seems unreasonable – what reason should a retraction have in that case? Especially when both parties are so eager to underline that no confession of guilt or blame is made.
Seems like I’m not the only one wondering about this course of events:
I’m pretty sure that this is not the end of the discussion and that there will be other investigations.
Inspired by a recently published article in the ZEIT (in German only), I did some further reads on the topic of mosaicism. The bottom line: contrary to common belief and what is taught in text books (and University courses), the human body does not consist of cells with a single, personal genome, but instead each cell or cell-cluster has it’s own personal genome. A phenomenon that is also called “mosaicism”.
Until recently we needed a bunch of cells that were used to sequence our DNA, but today we are able to look on our genes on a single-cell basis. Findings now reveal a new theory on how our cells and tissue has evolved and allows for new theories on somatic and psychiatric illnesses.
From a review by Biesecker and Spinner (2013):
It has long been known that cancer is a mosaic genetic disorder, but mosaicism is now apparent in a diverse range of other clinical disorders, as indicated by their tissue distributions and inheritance patterns. Recent technical advances have uncovered the causative mosaic variant underlying many of these conditions and have provided insight into the pervasiveness of mosaicism in normal individuals.
This not only changes how we should think about the genetic basis of diseases but also about the genetic basis for personality and “normal” human behavior.
From this findings new theories of genetics and the genetic causes of human differences and diseases will emerge. We are not a single piece of cells with a pre-determined DNA, but a bunch of cells with different and still ongoing mutations in a DNA, that begun with only a single cell. This is fascinating and shows the ever-evolving nature of science and that we have by no means already “discovered everything that can be discovered”.
Not directly related to my field of research, but a very interesting story from a patient who lost memories due to a craniopharyngioma and gains them back as the tumor is removed:
What eventually did happen was something none of the experts ever suggested would be possible. Over time I would lose my memory—almost completely—of things that happened just moments before, and become unable to recall events that happened days and years earlier. To the rest of the world, I would become a young man behaving bizarrely, perhaps drunkenly, and I lacked the ability to acknowledge it, or fully explain what was going on. As it grew, eventually to the size of a small egg, the tumor dug a hole in my consciousness, of ever-increasing depth. I became incapable of living the life I had made for myself.

It’s quite a long read but you might want to save it later for your next afternoon or weekend read.
Okay, schon wieder ein Blog. Ja, ich habe in den letzten Jahren immer wieder neue Blogs aufgemacht. Und ja, die haben selten länger als ein Jahr gehalten. Trotzdem habe ich noch mal einen neuen Anlauf gestartet.
Und wieso? Seit Anfang Oktober arbeite und promoviere ich in der Abteilung Methodenlehre, Diagnostik und Evaluation an der Uni Bonn. Das führt dazu, dass ich häufiger mal interessante Paper lese und da irgendwie meinen Senf zu abgeben möchte. In dieser Hinsicht richtet sich der Blog also an Interessierte jeglicher Herkunft und Fachrichtung.
Damit das alles aber nicht zu langweilig wird, könnten hier – bitte nicht erschrecken – auch mal Fotos oder ähnliches auftauchen. Und um die
Komplexität Internationalität zu steigern, werden einige Posts sicherlich auch mal auf Englisch kommen.
Keine Ahnung, ob das jetzt länger als ein Jahr klappt, aber ich dachte mir: Ich versuch’s einfach mal wieder.
