Conflict of interest statement

To be commercially successful with a company like AllGoodSpeakers ApS and its German branch Charismatischer.de in an area in which one also conducts research inevitably brings with it the question of a conflict of interest. It is important for me to emphasize here that I take this question seriously, and that I want to deal with it responsibly and transparently. I would also like to emphasize that for me I do not see a conflict of interest in the strict sense. There are various reasons for this, which I would like to briefly explain below. Please note that this statement and all explanations were agreed with the Research Ethics Committee of the University of Southern Denmark (SDU).

 

The first reason

…is that a conflict of interest in the strict sense always presupposes that the research conducted seeks to achieve a certain desired result. Imagine the typical case of a researcher being paid by a food or tobacco company to analyze the effects of the respective product on the consumer's body and health. A result showing that, for instance, the product’s sugar or fat content is harmful or that smoking significantly increases the risk of cancer would certainly be less desirable on the part of the paying company than the respective opposite result. In the charisma research of me and my colleagues, there is no such desired result. On the contrary, our goal is to understand, analyze and, ultimately, train the complex multimodal system of (non-verbal) signals that determine the perceived charisma of the speaker. Any finding is desirable in this connection and brings us closer to achieving this goal. It does not matter whether a finding contradicts information in the advice literature or not. We have made both types of findings in the past and communicated both equally openly and made them the subject of our analysis and training measures. It also doesn't matter whether a finding comes from our team or not. Accordingly, we always aim to keep an eye on the state of research on the subject of charisma as a whole and, if it makes sense, to implement new knowledge accordingly (with reference to the source, if applicable).

 

The second reason

…is that we have not published any research that was from the outset carried out with a corporate, commercial perspective. This applies, for example, to the results and metrics behind the PICSA algorithm for charisma assessment, but also to other research on hardware and software that, in the sense of the above example, could be suspected of achieving a desired result. There may be publications that give a different impression, for example in the case of software and hardware tools. In these cases, however, the study in question was either carried out after the tool had been successfully tested and introduced, or it was research that was otherwise externally funded (e.g., in the case of the MARRYS cap).

 

The third reason

…is that I am not directly financially dependent on the commercial activities of AllGoodSpeakers ApS or Charismatischer.de. Neither am I in a traditional employment relationship with the company based on a regular income nor do I receive any money from the company's activities directly. I just hold shares in the company and do what I do, because I really enjoy building up something, and because it inspires and motivates my spirit of research; and not least because it is very fulfilling to help people, especially those who feel insecure and anxious about public speaking and giving presentations. In view of this, I refer back to the first reason, because one can only help others effectively if one properly understands the production and perception of speaker charisma, regardless of whether a specific result is desirable or not and/or comes from our own team or not.

 

In summary

For the reasons mentioned, I do not see myself and my colleagues in a conflict of interest (COI) in the strict sense, and therefore unfortunately did not consider it necessary (actually not even thought about it) from the outset to refer to such a conflict of interest in publications. However, I would like to thank those colleagues very warmly and sincerely who have drawn my attention to the fact that the mere lack of a COI statement could give the impression that there is a conflict of interest! They are right! I am grateful for the opportunity to make the above explanations explicit, which have prevented me so far from considering adding a COI statement to my publications.

 

I will refer to this website from now on in all relevant publications. In addition, wherever possible, I will try to add a reference to this website to all those previous papers that there published after AllGoodSpeakers ApS was founded in 2019, especially to those of which I am the first author.

 

Finally

I have also compiled a list of relevant publications below, divided into two groups; one in which I was involved in the data collection (group A) and one in which I was only involved in as an advisor or author (group B). Thank you for the support and for the interest, and I look forward to developing, sharing, discussing, and examining exciting, controversial, or simply remarkable experiences, observations and claims from the field of speaker charisma with you in the future.

 

With best regards,

Oliver Niebuhr.
